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.

- add support for LMC and LMG boards; some of the features might be
interesting to others:
o The flash on these boards is disjointed, e.g. mixed types for
different purposes. Therefore it is kept in different memory
regions.
o The Main Flash is interleaved betweed 2 StrataFlash parts,
necessitating some tricks to fit in with PPCBoot.
o Real software sector protection is used on the main StrataFlash
via flash_real_protect(). The Boot Flash doesn't support software
based sector protection.
o Specialized code is provided to download 1-6 Xilinx FPGAs.
o There is fairly extensive POST testing of some board subsystems.
Some of this code could be reused on other targets. The SDRAM bus
and RTC battery checks come to mind.

Fix some HUSH problems.
In the current implementation, the local variables space and global
environment variables space are separated. Local variables are those
you define by simply typing like `name=value'. To access a local
variable later on, you have write `$name' or `${name}'; variable
directly by typing say `$name' at the command prompt.
Global environment variables are those you use setenv/printenv to
work with. To run a command stored in such a variable, you need to
use the run command, and you must not use the '$' sign to access
them.
To store commands and special characters in a variable, please use
double quotation marks surrounding the whole text of the variable,
instead of the backslashes before semicolons and special symbols.

For binary compatibility with older Linux kernels (which expect the
clocks passed in the bd_info data to be in MHz) the environment
variable "clock_in_mhz" can be defined so that PPCBoot converts
clock data to MHZ before passing it to the Linux kernel. When
CONFIG_CLOCKS_IN_MHZ is defined in the board config file, a
definition of "clock_in_mhz=1" is automatically included in the
default environment.

CFG_CLKS_IN_HZ option such a #define has been added to the config
