Cleanup for M5271EVB:
Added clarification on the use of CONFIG_SYS_CLOCK.
Modified to use u-boot's HUSH parser.
Cleanup on environment settings.
Removed compiler warning by defining CONFIG_SYS_CS0_*
Dependencies:
Added the use of CONFIG_SYS_MCF_SYNCR for clock multiplier.
This depends on a patch to include/asm-m68k/m5271.h
that defines the multiplier and divider ratios.
Removed the definition of CONFIG_SYS_FECI2C.
This depends on a patch that removes the use of it in
cpu/mcf52x2/cpu_init.c

M5271 dynamic clock multiplier. It is currently fixed at 100MHz.
Allow the board header file to set their own multiplier and divider.
Added the #define for the multiplier and divider to the cpu header file.

Discontinue the use of CONFIG_SYS_FECI2C (only used by M5271EVB).
Use read-modify-write to activate the FEC pins without disabling I2C.

CONFIG_M68K bdinfo cleanup:
Fixed compiler warning about baudrate printing.
format '%d' expects type 'int', but argument 2 has type 'long unsigned int'.
Added printing of "cpufreq"

Added the CONFIG_M5271 to the list of Coldfire V2 processor. This
was causing the bus clock (not CPU clock) to be declared twice as
fast as it actually is. This causes UARTS to operate at half the
specified baudrate.

Rather than using 8bit transfers for everything, use 8/16/32 bit transfers
as usable with the source/destination addresses and the count size.

The performance difference from doing an 8 bit DMA memcpy vs an optimized
core memcpy can be pretty big when you add in the overhead of setting up the
MDMA registers, cache flushes, etc... So only use dma_memcpy() when we
actually require it.

We have to make sure the DMA channel is actually disabled in hardware before
attempting to reprogram it. Otherwise the new settings are ignored and we
end up with random hangs/failures.

Take the cache flush functions from the kernel as they use hardware loops in

Calculating the clocks requires a bit of calls to gcc math functions, so
cache the values after the first run since they'll most likely never
change once U-Boot is up and running.
