Several patches by Erik Theisen, 14 Oct 2001:
---------------------------------------------
- Fix udelay() for longer delays
- Fix wait_ticks() - don't treat timebase registers as signed
- Fix command name conflicts due to abbreviated length
- Add support for Apple's OS X host environment
- Add support for IBM 4xx DCR registers (commands "getdcr" and
"setdcr" to read and read/modify/write the 4xx DCR)
- Sort command table alphabetically and in descending string length
order to prevent conflicts; added doc/README.commands
- add "reset" option to help info for "date" command
- add support for the ST Electronics M48T35Ax Timekeeper RTC
- add support for "flash_real_protect()" for flash chips that provide
software sector protection routines, e.g. Intel StrataFlash (board
specific code)
- 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.
NOTE: still serious quoting problems! cannot access env vars in commands!

Patch by Morten Brørup, 27 Aug 2001
PPCBoot stores all clock information in Hz internally.
####################################################################
# WARNING: #
# This will cause binary incompatibility with older Linux kernels! #
####################################################################
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.
NOTE: for all boards that did not use the (now obsolete)
CFG_CLKS_IN_HZ option such a #define has been added to the config
file.
