        * cdl/hal_i386_pcmb.cdl: 
        * include/pcmb_io.h: Increase PCI space to include all possible
        busses, slots, etc.  Required because defaults are often too small.     
2002-04-29  Gary Thomas  <gthomas@redhat.com>

        * src/pcmb_misc.c (hal_pcmb_init): Disable NMI at this point since
        no real handlers are in place to handle it.  This fixes a problem
        with manual reset code for IDE drivers which can cause NMI.

2002-04-26  Bart Veer  <bartv@redhat.com>

        * support/gfxmode.c:
        A utility to find out what graphics modes are available on any
        given PC.

        * include/pcmb.inc:
        Change the graphics mode during RedBoot startup, when configured
        to do so.       

        * cdl/hal_i386_pcmb.cdl:
        Add new configuration option for changing the graphics mode
        during RedBoot startup.

        * include/pcmb_serial.h: 
        * src/pcmb_serial.c:
        Added a simple validation test for serial devices. If the status
        register reads back all ones we decide that the device is absent
        and mark it invalid. We test this elsewhere to avoid touching the
        device again. This should help to cope with various problems with
        PCs that come with only one serial port.

2001-11-29  Jonathan Larmour  <jlarmour@redhat.com>

        * src/pcmb_screen.c: Restore sensible num lock behaviour after the
        last change.
        (KBScanTable): Fix scan table size.

2001-11-29 Trenton D. Adams  <tadams@theone.dnsalias.com>

        * src/pcmb_screen.c: Support numeric keypad and ctrl-alt-del for
        rebooting.

2001-11-23  Nick Garnett  <nickg@redhat.com>

        * include/pcmb_io.h (PC_WRITE_SCREEN): Wrap positions beyond end
        of screen back to start.
        
2001-11-01  Jonathan Larmour  <jlarmour@redhat.com>

        * src/pcmb_misc.c (hal_pcmb_init): Fix typo:
        CYGPKG_HAL_I386_PCMB_HAL_MEMSIZE_BIOS -> 
        CYGPKG_HAL_I386_PCMB_MEMSIZE_BIOS

2001-10-19  Ian Campbell  <icampbell@arcom.co.uk>

        * cdl/hal_i386_pcmb.cdl: Add cdl_options for
        CYGPKG_HAL_I386_PCMB_MEMSIZE to allow configuration of how memory
        is detected. Change CYGNUM_HAL_RTC_PERIOD to use default_value
        rather than calculated (so it can be overridden in the platform).
        * src/pcmb_misc.c: Implement CYGPKG_HAL_I386_PCMB_MEMSIZE
        configuration options.
        
2001-10-16  Mark Salter  <msalter@redhat.com>

        * src/pcmb_serial.c (cyg_hal_plf_serial_init): Use CDL to determine
        how many serial ports to support.
        * src/pcmb_screen.c (cyg_hal_plf_screen_init): Use CDL to determine
        channel number for keyboard/screen.

2001-10-01  Ian Campbell  <icampbell@arcom.co.uk>

        * include/pcmb_io.h: Include CYGBLD_HAL_PLATFORM_H rather than
        <pkgconf/hal_i386_pc.h>. Also include <pkgconf/system.h> so the
        define is available.

2001-09-14  Mark Salter  <msalter@redhat.com>

        * include/pcmb_io.h (HAL_IDE_READ_ALTSTATUS): Add 2 for correct offset.
        (HAL_IDE_WRITE_CONTROL): Ditto.

2001-08-22  Nick Garnett  <nickg@redhat.com>

        * src/pcmb_misc.c: Added spinlock to clock read operation.
        
        * include/pcmb_io.h (PC_WRITE_SCREEN_*): Added casts to make these
        macros more universal.

        * src/pcmb_smp.c: Added this file to contain all SMP related
        code. This includes parsing the MP structures; initializing the
        APIC and IOAPIC; starting the CPUs; interrupt mapping; inter-CPU
        interrupts; and CPU synchronization in the event of a debuggable
        exception.
        Note: there is still a _lot_ of debugging code in here, mostly
        disabled, which needs cleaning up. Also, if this code is to ever
        be released to the public, it should probably be tidied up a bit
        more.

        * include/pcmb_intr.h: Added SMP support. This includes the
        inter-CPU interrupt vectors, interrupt masking, acknowledge, and
        CPU affinity via the APIC and IOAPIC.

        * cdl/hal_i386_pcmb.cdl: Added configury to compile pcmb_smp.c
        only when SMP is enabled. Also define HAL_PLATFORM_EXTRA to
        contain the SMP-ness of the HAL, so that RedBoot can report it.

2001-07-31  Mark Salter  <msalter@redhat.com>

        * include/pcmb_io.h: Add IDE I/O macros.
        * cdl/hal_i386_pcmb.cdl: Now implements CYGINT_HAL_PLF_IF_IDE.

2001-07-18  Jonathan Larmour  <jlarmour@redhat.com>

        * include/pcmb_intr.h: Fill in interrupt table descriptions.

2001-07-05  Jonathan Larmour  <jlarmour@redhat.com>

        * src/pcmb_misc.c (hal_pcmb_init): Silence warning
        * include/pcmb_intr.h: Revert below change - not relevant in this case  
        for clobbers

2001-07-04  Jonathan Larmour  <jlarmour@redhat.com>

        * include/pcmb_intr.h: Be pedantic about register constraint syntax
        to satisfy newer compilers

2001-05-16  Jonathan Larmour  <jlarmour@redhat.com>

        * src/pcmb_misc.c (hal_pc_clock_initialize): Use mode 2 (rate generator)
        instead of mode 3 (square wave).

2001-05-03  Nick Garnett  <nickg@cygnus.co.uk>

        [x86 branch]    
        * cdl/hal_i386_pcmb.cdl: Changed option
        CYGIMP_HAL_I386_PCMB_SCREEN_SUPPORT to interface
        CYGINT_HAL_I386_PCMB_SCREEN_SUPPORT.

2001-03-14  Nick Garnett  <nickg@cygnus.co.uk>

        [x86 branch]
        * src/pcmb_misc.c:
        Added hal_pcmb_init() which currently extracts memory sizes out of
        CMOS RAM.
        Added hal_i386_mem_real_region_top() to return top of either base
        or extended memory regions.     

        * include/pcmb_io.h: Added CMOS RAM access macros.

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

        * cdl/hal_i386_pcmb.cdl:
        Added implement CYGINT_HAL_I386_MEM_REAL_REGION_TOP.

2001-03-13  Nick Garnett  <nickg@cygnus.co.uk>

        [x86 branch]
        * include/pcmb.inc: Removed redundant FPU code.

2001-03-09  Nick Garnett  <nickg@cygnus.co.uk>

        [x86 branch]
        * include/pcmb_intr.h: Rewrote HAL_INTERRUPT_ACKNOWLEDGE() and
        reinstated as main acknowledge mechanism.

2001-03-08  Nick Garnett  <nickg@cygnus.co.uk>

        [x86 branch]    
        * cdl/hal_i386_pcmb.cdl:
        * include/pcmb.inc:
        * include/pcmb_intr.h:
        * include/pcmb_io.h:
        * include/pcmb_serial.h:
        * src/pcmb_misc.c:
        * src/pcmb_screen.c:
        * src/pcmb_serial.c:
        Created this package to provide the support needed to run eCos
        binaries on an i386 PC using a standard motherboard. This package
        provides support for the standard PC devices: timers, interrupt
        controller, serial ports, ASCII display, keyboard, PCI bus
        etc. that are found on all PC compatible platforms.  It does not
        provide support for devices that may also be found on modern
        motherboards, such as ethernet, sound and video devices. These are
        supported by drivers elsewhere.
