        CYG_HAL_GDB_ENTER_CRITICAL_IO_REGION() instead of simply disabling

        stepping and watching variables when this code to output a whole
        GDB $O packet is entered.

1999-09-20  Hugo Tyson  <hmt@cygnus.co.uk>

        * include/pkgconf/hal_powerpc_mbx.h (CYGHWR_HAL_POWERPC_BOARD_SPEED): 
        Missing default value (wouldn't build sans ConfigTool).

1999-09-09  Gary Thomas  <gthomas@cygnus.co.uk>

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

1999-07-27  Hugo Tyson  <hmt@cygnus.co.uk>

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

1999-06-28  Hugo Tyson  <hmt@cygnus.co.uk>

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

1999-06-28  Hugo Tyson  <hmt@cygnus.co.uk>

        * 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  <hmt@cygnus.co.uk>

        * 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  <gthomas@cygnus.co.uk>

        * 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  <hmt@cygnus.co.uk>

        * 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  <hmt@cygnus.co.uk>

        * 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  <hmt@cygnus.co.uk>

        * 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  <jld@cygnus.co.uk>

        * 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  <hmt@cygnus.co.uk>

        * 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  <hmt@cygnus.co.uk>

        * 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  <jskov@cygnus.co.uk>

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

1999-06-17  Hugo Tyson  <hmt@cygnus.co.uk>

        * 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  <hmt@cygnus.co.uk>

        * 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.

        * 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  <hmt@cygnus.co.uk>

        * 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/...]
