2011-08-25  John Dallaway  

        * misc/grub.cfg: Add example GRUB2 configuration file. Patch from

        Stephen Polkowski. [ Bugzilla 1001254 ]

2009-01-31  Bart Veer 

        * cdl/hal_i386_pc.cdl: update compiler flags for gcc 4.x

2005-06-20  Frank Pagliughi 

        * cdl/hal_i386_pc.cdl, include/pkgconf/mlt_i386_pc_grub_hi.*:

        Support for booting with GRUB in the High Memory.

2005-04-27  David Vrabel 

        * cdl/hal_i386_pc.cdl (CYGPKG_HAL_I386_PC_MEMSIZE): Moved from the

        pcmb package since it's PC specific.

        * src/pc_misc.c (hal_i386_mem_real_region_top): Moved from the

        pcmb package since it's PC specific.

        (hal_pc_init): Moved bits from the pcmb packaged related to

        hal_i386_mem_real_region_top.

2005-04-17  Andrew Lunn  

        * cdl/hal_i386_pc.cdl:

        * src/redboot_linux_exec.c: Moved the RedBoot command "exec" from

        this package to the generic architecture package.

2005-01-22  Ian Campbell  

        * cdl/hal_i386_pc.cdl,

        * src/redboot_linux_exec.c: Add a new RedBoot command "exec" which

        executes a Linux zImage or bzImage already loaded into RAM.

2004-08-14  David Brennan 

         * cdl/hal_i386_pc.cdl: Added capability to build redboot with GRUB

         startup type. Also added capability to load applications into a

         higher RAM address (2MB) so they work with new GRUB based redboot.

         * include/pkgconf/mlt_i386_pc_ram_hi.mlt:

         * include/pkgconf/mlt_i386_pc_ram_hi.h:

         * include/pkgconf/mlt_i386_pc_ram_hi.ldi: New files for loading

         applications at 2MB.

         * misc/redboot_GRUB.ecm: New file for creating GRUB loadable

         redboot

2004-04-22  Jani Monoses 

         * cdl/hal_i386_pc.cdl :

         Invoke tail with stricter syntax that works in latest coreutils.

2003-07-23  Nick Garnett  

        * include/plf_intr.h: Added extern definition for hal_pc_reset().

2003-04-10  Nick Garnett  

        * include/pkgconf/mlt_i386_pc_rom.ldi: Brought list of sections up

        to date with other files.

2003-01-22  Jonathan Larmour  

        * include/pkgconf/hal_i386_pc.h: Old file. Remove.

2002-11-28  Nick Garnett  

        * src/plf_stub.c: Removed redundant reinitialization of VSR table

        in hal_pc_stubs_init(). This has already been done in

        hal_platform_init() and reinitializing here destroys the FPU

        switch VSR.

        * src/plf_misc.c (hal_platform_init):

        Added configuration and test to avoid overwriting the FPU switch

        VSR with the default VSR. This caused problems with stand-alone

        application that use lazy FPU switching.

        Moved call to hal_ctrlc_isr_init() to after call to

        hal_if_init(). Previously, stand-alone applications had problems

        with ctrl-c handling because the CALL_HACK stuff didn't work.

        * cdl/hal_i386_pc.cdl:

        Added GRUB startup option. This enables support for booting from

        the GRUB bootloader.

        Added CYGDBG_HAL_DEBUG_GDB_INITIAL_BREAK option to force a

        breakpoint just before calling cyg_start(). This is insinuated

        into the CYGPKG_HAL_DEBUG part of the tree, and conditioned to

        only work for stand-alone apps with the stubs included.

        * include/platform.inc: Added GRUB startup support.

        * include/pkgconf/mlt_i386_pc_grub.mlt:

        * include/pkgconf/mlt_i386_pc_grub.ldi:

        * include/pkgconf/mlt_i386_pc_grub.h:

        Added these MLT files to support the new GRUB startup option.

        * misc/menu.lst: Added this example GRUB menu configuration file.

2002-05-07  Gary Thomas  

        * cdl/hal_i386_pc.cdl:

        Standardize CYGNUM_HAL_VIRTUAL_VECTOR_CONSOLE_CHANNEL_DEFAULT usage.

2002-04-29  Jonathan Larmour  

        * src/romboot.S:

        Don't use .file as it can confuse debugging since the .file

        doesn't contain the path and therefore the debugger will never

        know where it lives! This conflicts with using -Wa,--gstabs.

2002-04-23  Jonathan Larmour  

        * cdl/hal_i386_pc.cdl: Remove unused compile line.

2001-12-07  Nick Garnett  

        * include/plf_intr.h: Added definition of HAL_DELAY_US() so that

        this is used instead of the delay loop in delay_us(). This is

        necessary to handle fast Pentiums and Athlons.

        * misc/redboot_FLOPPY_D850GB.ecm: Removed reference to SMP.

2001-10-16  Mark Salter  

        * misc/redboot_FLOPPY_D850GB.ecm: New file. RedBoot config for

        Intel D850GB motherboard.

        * src/hal_diag.c: Setup pc_ser_channels based on CDL.

2001-10-12  Jonathan Larmour  

        * cdl/hal_i386_pc.cdl: Parent CYGBLD_BUILD_REDBOOT_BIN_ROM and

        CYGBLD_BUILD_REDBOOT_BIN_FLOPPY under a CYGBLD_BUILD_REDBOOT_BIN_ROM

        component for better cross-platform consistency.

2001-10-08  Ian Campbell  

        * cdl/hal_i386_pc.cdl: CYGBLD_BUILD_I386_ROMBOOT and

        CYGBLD_BUILD_REDBOOT_BIN_ROM moved here from hal_i386.cdl in the

        arch package. Rename CYGBLD_BUILD_REDBOOT_BIN to

        CYGBLD_BUILD_REDBOOT_BIN_FLOPPY for consistency.

        * src/romboot.S: Moved from arch package.

        * src/romboot.ld: Moved from arch package.

2001-10-05  Mark Salter  

        * src/plf_stub.c (hal_pc_stubs_init): Install idt entry for GNUPro

        syscalls.

        * misc/redboot_FLOPPY.ecm: Turn on CYGSEM_REDBOOT_BSP_SYSCALLS.

        * include/plf_misc.h: Add extern decl for cyg_hal_pc_set_idt_entry.

2001-10-02  Jonathan Larmour  

        * cdl/hal_i386_pc.cdl

        (CYGNUM_HAL_VIRTUAL_VECTOR_CONSOLE_CHANNEL_DEFAULT): Allow user to

        change value.

2001-09-28  Ian Campbell  

        * include/platform.inc (hal_cpu_init): Initialise %ss.

        Be more pedantic about register names matching opcode suffixes.

2001-09-07  Jonathan Larmour  

        * misc/redboot_FLOPPY.ecm: Disable

        CYGSEM_REDBOOT_VALIDATE_USER_RAM_LOADS

        * misc/redboot_ROM.ecm: Ditto.

        * misc/redboot_FLOPPY_SMP.ecm: Ditto.

2001-09-05  Jonathan Larmour  

        * src/plf_misc.c (hal_platform_init): If not RAM startup, install

        exception VSRs.

2001-08-22  Nick Garnett  

        * include/pkgconf/mlt_i386_pc_floppy.ldi:

        * include/pkgconf/mlt_i386_pc_floppy.mlt:

        Moved load base address from 0x2000 to 0x3000.

        We now use page 0x2000 for SMP related data including the slave

        CPU startup trampoline and various data structures that need to be

        shared between RedBoot and the application.

        * misc/redboot_FLOPPY_SMP.ecm: Added this file to configure an

        SMP-aware RedBoot floppy. If SMP applications are to be run it is

        essential that this version of RedBoot be used because a degree of

        cooperation is required to get the CPUs going, and to handle

        exceptions cleanly.

        * src/plf_misc.c (hal_platform_init): Added call to cyg_hal_smp_init().

        * include/platform.inc (hal_idt_init): Added entries to set up IDT

        entries 48..67.

2001-08-13  Jonathan Larmour  

        * cdl/hal_i386_pc.cdl: Fix CYG_HAL_STARTUP description.

2001-07-13  Nick Garnett  

        * cdl/hal_i386_pc.cdl: Added requires statement to

        CYGSEM_HAL_ROM_MONITOR option to turn off lazy FPU switching. ROM

        monitors should not be playing these kinds of games.

2001-05-22  Jonathan Larmour  

        * include/pkgconf/mlt_i386_pc_ram.mlt: Fix pci_window description.

2001-05-03  Nick Garnett  

        * cdl/hal_i386_pc.cdl: Changed option

        CYGIMP_HAL_I386_PCMB_SCREEN_SUPPORT to interface

        CYGINT_HAL_I386_PCMB_SCREEN_SUPPORT.

2001-04-30  Nick Garnett  

        [x86 branch]

        * cdl/hal_i386_pc.cdl: Added options to convert ELF file to binary

        for copying to a floppy disc.

2001-03-16  Nick Garnett  

        [x86 branch]

        * misc/redboot_ROM.ecm:

        Removed ETH_DRIVERS package for initial work.

        (This is work in progress and is not yet complete.)

        * include/pkgconf/mlt_i386_pc_rom.ldi:

        * include/pkgconf/mlt_i386_pc_rom.h:

        Added these files to enable building of ROM images.

        (This is work in progress and is not yet complete.)

        * include/platform.inc: Modified ROM startup to work with romboot.S.

        * cdl/hal_i386_pc.cdl: Modified options to allow for ROM startup.

        * include/pkgconf/mlt_i386_pc_ram.mlt:

        * include/pkgconf/mlt_i386_pc_ram.ldi:

        * include/pkgconf/mlt_i386_pc_ram.h:

        Fixed some bugs in these files with the size and layout of

        RAM. This was causing the heap to be badly mangled.

2001-03-14  Nick Garnett  

        [x86 branch]

        * src/plf_misc.c (hal_platform_init): Added call to

        hal_pcmb_init().

        * include/platform.inc: Removed memory size stuff.

2001-03-13  Nick Garnett  

        [x86 branch]

2001-03-08  Nick Garnett  

        [x86 branch]

        * src/plf_misc.c: ISR tables and cyg_hal_pc_set_idt_entry() moved

        here from hal_startup.c. ISR table setup code tidied.

        hal_delay_us() now works in 1s bursts to avoid arithmetic

        overflow.

        * src/hal_diag.c: Most of contents of file moved out to

        pcmb_serial.c and pcmb_screen.c. This remains as an intialization

        interface for those.

        * include/plf_io.h: Move contents out to pcmb_io.h.

        * include/plf_intr.h: Added include of pcmb_intr.h and other

        headers.

        * include/plf_arch.h: File added. Currently contains nothing.

        * include/platform.inc: floppy boot code moved to PCMB HAL. FPU

        support moved to architectural HAL. Various tidies.

        * cdl/hal_i386_pc.cdl: Many changes to bring this HAL in line with

        reorganization of whole i386 HAL. Lots of stuff deleted, and other

        things moved out to PCMB package.

        * misc/redboot_FLOPPY.ecm: Added setting of CYGSEM_HAL_ROM_MONITOR

        to 1.

        * include/var_intr.h:

        * include/variant.inc:

        * src/hal_intr.c:

        * src/hal_startup.c:

        * src/var_misc.c:

        Files removed. Most of the contents of these files has become

        redundant. Those parts that are not have been moved to more

        appropriate places.

2001-03-06  Nick Garnett  

        [x86 branch]

        * src/var_misc.c: Rewrote clock init and access functions in terms

        of HAL IO macros.

        * src/plf_misc.c:

        Added call to HAL_CLOCK_INITIALIZE() to hal_platform_init() when

        in RedBoot configurations.

        Rewrote hal_delay_us() to use timer 0.

        * misc/redboot_FLOPPY.ecm: Added ETH drivers to configuration.

        * include/pkgconf/mlt_i386_pc_floppy.ldi:

        * include/pkgconf/mlt_i386_pc_floppy.h:

        Added __pci_window label for use with PCI devices.

        * include/plf_misc.h: Removed unnecessary port IO functions.

        * include/plf_io.h:

        Gave correct values to HAL_PCI_PHYSICAL_MEMORY_BASE and friends.

        Tidied up a bit.

2001-03-05  Nick Garnett  

        [x86 branch]

        Some of these changes were initially made by Fabrice Gautier and

        then liberally modified by me.

        * src/var_misc.c: Miscellaneous tidies.

        * src/plf_misc.c (hal_platform_init): Some redundant stuff

        removed.

        * src/plf_stub.c:

        * src/hal_startup.c:

        * src/hal_intr.c:

        Lots of stuff removed from these files. When we reorganise the

        HAL, these files should be eliminated.

        * src/hal_diag.c:

        Lots of changes to support IF vectors for both serial ports and

        screen/keyboard.

        * misc/redboot_FLOPPY.ecm:

        * include/pkgconf/mlt_i386_pc_ram.ldi:

        * include/pkgconf/mlt_i386_pc_ram.mlt:

        Updated to reflect new memory layout for Redboot and RAM apps.

        * include/var_intr.h: Tidied up and made consistent with rest of

        HAL. HAL_TRANSLATE_VECTOR() used where necessary.

        * include/plf_stub.h: Some minor changes and tidies.

        * include/plf_misc.h: Tidied up. This file should eventually

        become redundant.

        * include/plf_io.h: New file - contains PCI support code.

        * include/plf_intr.h: Added HAL_PLATFORM_RESET_ENTRY.

        * include/platform.inc:

        Better separation of startup types, added start of ROM startup.

        Added IDT initialization. Various tidies.

        * include/hal_diag.h: Added virtual vector support.

        * cdl/hal_i386_pc.cdl: Many changes to support Redboot.

2001-01-26  Jesper Skov

        * include/plf_intr.h: to this file.

2000-12-05  Hugo Tyson  

        * src/plf_misc.c (hal_pc_fpe_dsr): Raise the base stack address by

        CYGNUM_KERNEL_THREADS_STACK_CHECK_DATA_SIZE if that is defined;

        otherwise a stack overflow would immediately be reported.

2000-11-02  Fabrice Gautier 

        * src/platform.inc (hal_cpu_init): Load image from floppy one

        sector at a time to avoid "DMA access across 64k boundary" error.

2000-10-20  Jonathan Larmour  

        * include/pkgconf/mlt_i386_pc_floppy.mlt:

        Add heap1 section

        * include/pkgconf/mlt_i386_pc_floppy.h:

        * include/pkgconf/mlt_i386_pc_ram.h:

        * include/pkgconf/mlt_i386_pc_floppy.ldi:

        * include/pkgconf/mlt_i386_pc_ram.ldi:

        Regenerated

2000-10-19  Jesper Skov  

        * include/pkgconf/mlt_i386_pc_ram.h: Added heap1 label.

        * include/pkgconf/mlt_i386_pc_ram.mlt: Same.

        * include/pkgconf/mlt_i386_pc_ram.ldi: Same.

2000-08-18  Nick Garnett  

        * include/platform.inc:

        * include/var_intr.h:

        Fixed code to acknowledge interrupts to always ack on the master

        controller and ack the slave controller when it is INT8 or higher.

2000-06-20  Nick Garnett  

        * include/var_intr.h: Added cast to _data_ argument in

        HAL_INTERRUPT_ATTACH() to prevent compiler errors.

2000-03-23  Nick Garnett  

        * doc/RELEASENOTES.txt: Added this file to contain release notes.

2000-03-15  Nick Garnett  

        * src/hal_diag.c: Added code to handle keyboard input on PC when

        using SCREEN diagnostics. This is as much for completeness and

        future use than for any pressing current need.

        * include/platform.inc: Fixed some mismatches between instruction

        suffixes and operand sizes that the latest i386 assembler now

        warns about. Also tidied up GDT and IDT load code and protected

        mode switch because of warnings from assembler.

2000-03-09  Jesper Skov  

        * include/platform.inc:

        * cdl/hal_i386_pc.cdl: Rename CYGHWR_HAL_STARTUP to

        CYG_HAL_STARTUP for consistency with other HALs (and tools).

2000-03-02  Jonathan Larmour  

        * cdl/hal_i386_pc.cdl (CYGBLD_GLOBAL_COMMAND_PREFIX):

        Use i386-elf toolchain by default, although add a note in the

        description that appropriate versions of native linux tools can

        also be used.

2000-03-01  Nick Garnett  

        * src/plf_stub.c (cyg_hal_gdb_isr): Added check for a character

        being available at the serial line. With the introduction of GDB O

        packet debugging, it is possible for this code to see a spurious

        interrupt and get stuck in hal_pc_get_char().

        * include/var_intr.h:

        Modified interrupt enable/disable code so that it is closer in

        behavior to other HALs.

        * include/platform.inc:

        Changed floppy bootstrap code so it can load binaries greater than

        64k and only loads the .text+.data parts, not the .bss.

2000-02-18  Jonathan Larmour  

        * cdl/hal_i386_pc.cdl (CYGBLD_BUILD_GDB_STUBS): When

        building stubs, define every dependency required here rather than

        in the template

2000-02-18  John Dallaway  

        * include/pkgconf/mlt_i386_pc_ram.mlt,

          include/pkgconf/mlt_i386_pc_floppy.mlt:

        Add/update memory layout save files to match the corresponding

        linker script fragments.

2000-02-16  Nick Garnett  

        * src/hal_diag.c: Added support for generating GDB O packets when

        diagnosing to serial0.

        * include/plf_intr.h: Added missed copyright notice.
