c924098122 [ppc440SPe] Graceful recovery from machine check during PCIe configuration
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.

1b305bdc75 Search the exception table with linear algorithm
Search the exception table with linear algorithm instead of
bisecting algorithm.
Because the exception table might be unsorted.

c9c1eeed7d Fix the exception occuring in RAM table search issue.
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.

clean up the code in cpu/74xx_7xx/cpu.c

4c52783b3d General code modification for mpc7448hpc2 board support.
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.

There is a design issue for tsi108/109 pci configure  read. When pci scan
the slots, if there is no pci card, the tsi108/9 will cause a machine
check exception for mpc7448 processor.
