#1: - allow generation of GNU stabs line number debugging symbols
for assembly sources ; this allows symbolic debugging of
assembly files.
- fix probelms due to CYGWIN patches
#2: - Fix BEDBUG lossage when using GPR 0 in assembly mode.
- Allow BEDBUG to have a choice in whitespace between operand
delimiters.
- All PPC40x targets had the wrong cacheline size defined in
their config files. It should be 32 bytes for 405's and 16
bytes for CPUs prior to the 405.
- Make sure boards don't use deprecated CONFIG_4xx anymore.
- Make sure 405 MAL Ethernet buffer descriptors are malloc'd
and aligned on cache boundaries instead of being located at
a hard coded address. This was causing lossage on boards
with less than 16MB of RAM.
- IBM Walnut boards use 33.3Mhz clocks. Prevents rounding.
- Added a couple of 4xx specific defines.
#3: - Fix compiler warnings
- Make sure inline assembly statements properly flag
registers that are being modified.
#4: - cleanup of common/cmd_i2c.c; eliminated board specific
conditionals; eliminated deprecated CONFIG_I2C405 config
option.
- Added _i2c_bus_reset function to ${CPU}/ppc4xx/i2c.c to
handle reset edge condition which was causing EEPROM data
corruption. See doc/I2C_Edge_Conditions for details.
#5: - Add generic SDRAM SPD, "Serial presence detect," routines.
These should work with any 405 based boards that are using
SPD.
- Make IBM Walnut target use these new routines.
- Added ablility to place initial stack into 405's OCM, "On
Chip Memory."
- Added resetvec address to initial stack to aid in debugging
and also cause a reset in the event of an underflow.
#6: - Add digital temperature and thermostat support
- Add support for Dallas DS1621 and On Semi's LM75 DTTs.

Series of patches by Erik Theisen, 25 Nov 2001:
Patch 1 of 9:
- common/environment.S replaced by C file; necessary because:
a) People were defining CONFIG_BOOTCOMMAND, CONFIG_BOOTARGS and
other CONFIG parameters as a list of whitespace separated
strings. C does the right thing and concatenates them for
common/cmd_nvedit.c.
b) Was only working for common/environment.S in ppcboot and
tools/envcrc due to a bug in GNU 'as' in that it accepts a
list of whitespace seperated strings and treats them as comma
separated. The GNU 'as' manual explitly states:
`.ascii' expects zero or more string literals (*note
Strings::) SEPARATED BY COMMAS. It assembles each string
(with no automatic trailing zero byte) into consecutive
addresses.
c) Could not build tree on several commercial UNIX's because some
of them do not use GNU 'as'. Therefore the bug in item 'b' was
causing lossage on these platforms (Solaris, Mac OS X).
d) Some UNIXes as well as other OSs prepend leading characters to
symbol names (Motorola V68/Mac OS X/Mach/Others).
common/environment.S had no prevision for this and was causing
build failures for tools/envcrc due to unresolved symbols.
Patch 2 of 9:
- avoid Korn Shellism in MAKEALL Bourne shell script
- Fix build problems caused by non-exported TEXT_BASE,
PLATFORM_CPPFLAGS, and PLATFORM_RELFLAGS make variables.
- Explictly setting PLATFORM_CPPFLAGS and PLATFORM_CPPFLAGS to
nothingness in config.mk was causing lossage on Solaris and Apple
platforms.
- Specialized Makefile host settings in tools directory allows
clean builds on Mac OS X. See comment in tools/Makefile.
Specialized host settings are passed to tools/gdb/Makefile

- Added tools/envcrc support for the new common/environment.c
- Mac OS X uses cc NOT gcc. Added support for this.
