2000-01-19  Hugo Tyson  

        * cdl/*.cdl: Add descriptions to a number of options &c which were

        * src/hal_diag.c (hal_diag_write_char): Call new hal_stub.h macro

        CYG_HAL_GDB_ENTER_CRITICAL_IO_REGION() instead of simply disabling

        interrupts, ditto for enable.  This provides atomicity wrt single

        stepping and watching variables when this code to output a whole

        GDB $O packet is entered.

1999-09-20  Hugo Tyson  

        * include/pkgconf/hal_powerpc_mbx.h:

        (CYGHWR_HAL_POWERPC_MBX_BOOT_32BIT_FLASH) new config option to

        control chip select initialization.

        * src/mbx.S: Take notice of CYGHWR_HAL_POWERPC_MBX_BOOT_32BIT_FLASH.

        * misc/stubrom.perm: Reference the new option for folks who want

        to boot from the 32-bit flash.

1999-09-13  Gary Thomas  

        * include/pkgconf/hal_powerpc_mbx.h (CYGHWR_HAL_POWERPC_BOARD_SPEED):

        Missing default value (wouldn't build sans ConfigTool).

1999-09-09  Gary Thomas  

        * include/pkgconf/hal_powerpc_mbx.h (CYGHWR_HAL_POWERPC_MBX_BOARD_SPEED):

        Rename CDL option to avoid a name clash.

1999-07-27  Hugo Tyson  

        * src/mbx.S: Fix typo in PLL setup value.  Reported from the net.

1999-06-28  Hugo Tyson  

        * src/hal_diag.c (hal_diag_init): Fix a "default type" warning.

1999-06-28  Hugo Tyson  

        * src/hal_diag.c (hal_diag_write_char): Only gobble the GDB ACK

        characters if there is no pre-ISR polling call to look for ^C

        chars to interrupt the prog.  (CYGDBG_HAL_DEBUG_GDB_BREAK_SUPPORT

        - should not be enabled if devices are in use)

1999-06-28  Hugo Tyson  

        * src/mbx.S (__upmtbl_start): We do not trust rewriting the UPMs

        for DRAM timing whilst running out of that very DRAM.  So only

        init UPMs in ROM start (including when making a stub rom).

1999-06-27  Gary Thomas  

        * src/hal_diag.c: Support buffering of diagnostic data for later

        display.  Controlled by CYGDBG_DIAG_BUF.  Also, turn on code to

        handle GDB ACK characters when stubs are enabled.

1999-06-25  Hugo Tyson  

        * src/mbx.S (__upmtbl_start): depending on CYG_HAL_ROM_MONITOR, we

        use the OLD TABLES if making a stub rom.  For greatest commonality

        of startup code between RAM startup development binaries and ROM

        startup "product" binaries we completely re-initialize the UPMs

        that control DRAM timing even in RAM start when executing out of

        that very DRAM.

        It appears that it is OK to rewrite the UPMs with the new timing

        data when already running with the old timing data, but not OK to

        update from new to new.  So we use the old timing data when

        building stubs.

        An alternative would be to conditionally not perform the UPM

        initialization in RAM startup, but that would weaken the testing

        value of RAM startup programs.

1999-06-24  Hugo Tyson  

        * src/mbx.S (__upmtbl_start): Use the new tables recently supplied

        by email from Motorola; without them, the cache-line-zero

        operation only zeros 12 bytes rather than 16.  [PR 20226]

1999-06-24  Hugo Tyson  

        * include/plf_stub.h (HAL_STUB_PLATFORM_INIT_BREAK_IRQ): Define

        this (empty) for it is required if HAL_DEBUG_GDB_BREAK_SUPPORT is

        enabled.  Improve HAL_STUB_PLATFORM_SET_BAUD_RATE.

1999-06-18  John Dallaway  

        * include/pkgconf/mlt_powerpc_mbx_rom.mlt:

        * include/pkgconf/mlt_powerpc_mbx_ram.mlt:

        Fix MLT save files to match the default linker script

        fragments.

1999-06-18  Hugo Tyson  

        * include/pkgconf/mlt_powerpc_mbx_rom.mlt:

        * include/pkgconf/mlt_powerpc_mbx_ram.mlt:

        Initial attempt at getting these to match the reality of the

        linker script fragment; we'll have to see whether they're right.

1999-06-18  Hugo Tyson  

        * src/mbx.S: Data cache setup in hal_hardware_init: set

        force-writethrough mode and explicitly disable little-endian swap

        mode, whatever _that_ is.  Force-writethrough is required if you

        are to enable the data cache, it crashes otherwise.  Cause

        unknown, could be the memory system doesn't support whatever

        access regime is used, or caching problems with loading code

        through the stubs?  In any case, this is a fine workaround.

        * src/hal_aux.c (CYGARC_MEMDESC_TABLE): Enable caching of the ROM;

        seems to do no harm, and helps ROM-based performance.

1999-06-18  Jesper Skov  

        * include/pkgconf/hal_powerpc_mbx.h: Fixed CDL description.

1999-06-17  Hugo Tyson  

        * misc/stubrom.perm: New file: a perm for creating an eCos stub

        ROM for the MBX.  Pro tem, ^C to break is not supported, so the

        feature must remain disabled.

        * include/plf_stub.h (HAL_STUB_PLATFORM_INIT): Diddle the LEDs if

        ROM start to distinguish eCos stub ROM from CygMon ROM from eCos

        app running/internal stubs.

1999-06-17  Hugo Tyson  

        * include/pkgconf/mlt_powerpc_mbx_rom.ldi: Move RAM usage in ROM

        startup to 2000 so that we can build stubs that don't fight with

        RAM started apps' RAM use from 10000.

1999-06-17  Hugo Tyson  

        * tests/PKGconf.mak: New file, to build that below.

        * include/pkgconf/hal_powerpc_mbx.h

        (CYGHWR_HAL_POWERPC_MBX_BOARD_SPEED): Add this config option to

        select 40MHz or 50MHz system clock speed.

        * src/mbx.S (hal_hardware_init): Complete system init for ROM

        start; move return address to inside the ROM from wherever we

        booted.  Proper board clock speed selection.

        * src/hal_diag.c (hal_diag_write_char_serial): Do not encode

        packets for GDB if using ROM start.

        * src/hal_aux.c (CYGARC_MEMDESC_TABLE): Map the ROM correctly so

        that ROM start works.

        * src/mbx.S (hal_hardware_init): Add full ROM-type startup code

        and some useful LED-diddling routines and macro, to assist in

        debugging ROM startup.

        * src/hal_aux.c (CYGARC_MEMDESC_TABLE): Enable memory mapping to

        the LED control register so that we can treak them with mem mgt

        enabled ie. in a normal execution context.

1999-06-11  Hugo Tyson  

        * src/mbx.S (hal_hardware_init): Set up the base address of the

        control registers in IMMR to 0xff000000 (as defined in arch).

        Turn off external interrupts, initialize the decrementer.

        * src/PKGconf.mak: Build the new file.

        * src/hal_aux.c (CYGARC_MEMDESC_TABLE): New file, to define this

        object for per-platform table-driven memory map initialization.

        The table used to be in hal_misc.c in the architectural HAL; this

        is platform dependent so better and cleaner here.

        * ChangeLog: Component created, based partly on the FADS work and

        on CygMon's serial IO code for the MBX860, to support the Motorola

        MBX860 development board.  Actual serial support lies in

        neighbouring component HAL_QUICC [hal/powerpc/quicc/...]
