Implementation of the do_bootm_linux() and other bootm helper routines is
architecture specific code. As such it resides in lib_<arch> directories
in files named <arch>_linux.c
This patch renames those files to a more clear and accurate
lib_<arch>/bootm.c form.
List of the renamed files:
lib_arm/armlinux.c -> lib_arm/bootm.c
lib_avr32/avr32_linux.c -> lib_avr32/bootm.c
lib_blackfin/bf533_linux.c -> lib_blackfin/bootm.c

This is an API for external (standalone) applications running on top of
U-Boot, and is meant to be more extensible and robust than the existing
jumptable mechanism. It is similar to UNIX syscall approach. See api/README
for more details.
Included is the demo application using this new framework (api_examples).
Please note this is still an experimental feature, and is turned off by
default.

During config transactions on the PCIe bus an attempt to scan for a
non-existent device can lead to a machine check exception with certain
peripheral devices. In order to avoid crashing in such scenarios the
instrumented versions of the config cycle read routines are introduced, so
the exceptions fixups framework can gracefully recover.

The patch by Heiko Schocher <hs@pollux.denx.de> on Jan, 19, 2007
fixes cfi_driver bug for mpc7448hpc2 board. The default cfi_driver can support
mpc7448hpc2 board.
The original search_one_table() function code can only processes the search
for the exception occurring in FLASH/ROM, because the exception and fixup
table usually locate in FLASH. If the exception address is also in
FLASH, it will be OK.
If the exception occurs in RAM, after the u-boot relocation, a
relocation offset should be added.

1. Add 7447A and 7448 processor support.
2. Add the following flags.
CFG_CONFIG_BUS_CLK : If the 74xx bus frequency can be configured dynamically
(such as by switch on board), this flag should be set.
CFG_EXCEPTION_AFTER_RELOCATE: If an exception occurs after the u-boot
relocates to RAM, this flag should be set.
CFG_SERIAL_HANG_IN_EXCEPTION: If the print out function will cause the
system hang in exception, this flag should be set.

Patch by Stefan Roese, 07 Sep 2006
Modifications are based on the linux kernel approach and
support two use cases:
1) Add O= to the make command line
'make O=/tmp/build all'
2) Set environement variable BUILD_DIR to point to the desired location
'export BUILD_DIR=/tmp/build'
'make'
The second approach can also be used with a MAKEALL script
'export BUILD_DIR=/tmp/build'
'./MAKEALL'
Command line 'O=' setting overrides BUILD_DIR environent variable.
When none of the above methods is used the local build is performed and
the object files are placed in the source directory.
Added code for reading and writing Mac addresses to/from ID EEPROM(0x57).
With attached patch, we can use command "mac/mac read/mac save/"
to read and write EEPROM under u-boot prompt.
U-boot will calculate the checksum of EEPROM while bootup,
if it is right, then u-boot will check whether the mac address
of eTSEC0/1/2/3 is availalbe (non-zero).
If there is mac address availabe in EEPROM, u-boot will use it,
otherewise, u-boot will use the mac address defined in
MPC8641HPCN.h. This matches the requirement to set unique mac address
for each TSEC port.

If problems are detected with this non default CAS latency,

-> TSEC is first device.
Patch by Stefan Roese, 30 Nov 2005
The global data pointer, stored in r29 before relocation to RAM, was
not initialized to a correct value. This happened because the pointer
declaration was done locally in the scope of the board_init_f()
function. What follows is a cite from gcc.info, 5.37, "Variables in
Specified Registers":
...
The compiler's data flow analysis is capable of determining where
the specified registers contain live values, and where they are
available for other uses. Stores into local register variables
may be deleted when they appear to be dead according to dataflow
analysis. References to local register variables may be deleted
or moved or simplified.
...
Moving the global data declaration to global scope solved the
problem.
