2002-12-13 Mark Salter <msalter@redhat.com>
 
* include/platform.inc: Fix memory size test. Reduce wait counts
for chip select 3 (16550 uart).
* misc/redboot_FLASH.ecm: Turn off hw flow control on 16550.
* misc/redboot_FULLRAM.ecm: Ditto.
* misc/redboot_RAM.ecm: Ditto.
* misc/redboot_ROM.ecm: Ditto.
 
* cdl/hal_mn10300_am33_asb2305.cdl: Add support for CPU serial ports.
* src/ser_asb.c: Support configurations no 16550 and with
builtin AM33 serial ports.
 
2002-12-06 Mark Salter <msalter@redhat.com>
 
* cdl/hal_mn10300_am33_asb2305.cdl (CYG_HAL_FULL_RAM): New option to
indicate if RAM startup should use all RAM. This allows a special
RAM startup to be built which may be loaded onto a bare board by
the MEI tools. This can be used to build an initial RedBoot which
is used to program the flash with the ROM startup RedBoot image.
Implement CYGINT_HAL_MN10300_MEM_REAL_REGION_TOP.
 
* misc/redboot_FULLRAM.ecm:
* include/pkgconf/mlt_mn10300_am33_asb2305_fullram.h:
* include/pkgconf/mlt_mn10300_am33_asb2305_fullram.ldi:
* include/pkgconf/mlt_mn10300_am33_asb2305_fullram.mlt: New files.
* include/pkgconf/mlt_mn10300_am33_asb2305_ram.h:
* include/pkgconf/mlt_mn10300_am33_asb2305_ram.ldi:
* include/pkgconf/mlt_mn10300_am33_asb2305_ram.mlt: Move ram base
so that ROM based RedBoot can load it.
 
* include/platform.inc: Add SDRAM runtime sizing.
 
2002-11-19 Mark Salter <msalter@redhat.com>
 
* cdl/hal_mn10300_am33_asb2305.cdl: Remove virtual vector comm support.
Add option to select platform serial port for comm channels. Add rules
to build RedBoot srec amd img file.
 
2002-11-15 Mark Salter <msalter@redhat.com>
 
* cdl/hal_mn10300_am33_asb2305.cdl: Override default VSR placement.
Removed unused options. Set correct clock speed.
* include/pkgconf/mlt_mn10300_am33_asb2305_ram.ldi: Remove unneeded
defines.
* include/pkgconf/mlt_mn10300_am33_asb2305_flash.ldi: Ditto.
* include/pkgconf/mlt_mn10300_am33_asb2305_rom.ldi: Ditto.
 
2002-11-14 Mark Salter <msalter@redhat.com>
 
* cdl/hal_mn10300_am33_asb2305.cdl: Remove RedBoot exec option. Now
provided in generic AM33 code. Ditto for RTC support.
* src/plf_misc.c: hal_delay_us now provided by AM33 package.
* src/redboot_cmds.c: Remove.
 
2002-08-02 Andrew Lunn <Andrew.Lunn@ascom.ch>
 
* cdl/hal_mn10300_am33_asb2305.cdl: Redboot exec command can now
be disabled by CDL
2001-10-18 David Howells <dhowells@redhat.com>
 
* cdl/hal_mn10300_am33_asb2305.cdl: change incorrect "BootFlash"
to "BootPROM" where specified.
* cdl/hal_mn10300_am33_asb2305.cdl: added support for booting
directly from the system flash.
* include/platform.inc: ditto.
* include/pkgconf/mlt_mn10300_am33_asb2305_flash.mlt: ditto.
* include/pkgconf/mlt_mn10300_am33_asb2305_flash.h: ditto.
* include/pkgconf/mlt_mn10300_am33_asb2305_flash.ldi: ditto.
* misc/redboot_FLASH.ecm: ditto.
 
2001-10-16 David Howells <dhowells@redhat.com>
 
* include/plf_io.h: made the CPU access PCI registers through the
uncached memmap reflection.
* cdl/hal_mn10300_am33_asb2305.cdl: moved the RTC configuration
previously added to MN10300 arch to the ASB2305 platform.
* include/platform.inc: display exception code on entry to NMI
handler and clear it on exit.
 
2001-10-15 David Howells <dhowells@redhat.com>
 
* misc/redboot_RAM.ecm: forced ethernet to switch down to 10Mbps
and switched syscall support on.
* misc/redboot_ROM.ecm: ditto.
 
* include/platform.inc: improved LED driving upon exception.
* src/plf_misc.c: ditto.
 
* include/pkgconf/mlt_mn10300_am33_asb2305_ram.mlt: PCI window moved.
* include/pkgconf/mlt_mn10300_am33_asb2305_ram.h: ditto.
* include/pkgconf/mlt_mn10300_am33_asb2305_ram.ldi: ditto.
* include/pkgconf/mlt_mn10300_am33_asb2305_rom.mlt: ditto.
* include/pkgconf/mlt_mn10300_am33_asb2305_rom.h: ditto.
* include/pkgconf/mlt_mn10300_am33_asb2305_rom.ldi: ditto.
 
2001-08-22 Gary Thomas <gthomas@redhat.com>
 
* src/redboot_cmds.c:
printf() is no longer a part of RedBoot. Thus all programs
must use diag_printf() and related functions instead.
 
2001-08-08 David Howells <dhowells@redhat.com>
 
* hal_mn10300_am33_asb2305.cdl: Generate binary RedBoot image
files as well as ELF ones.
 
2001-07-27 David Howells <dhowells@redhat.com>
