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.

Patch "flash/cfi_flash: Use virtual sector start address, not phys"
introduced a small compilation warning. This patch fixes it.
Signed-off-by: Stefan Roese <sr@denx.de>
include/flash.h was commented to say that the address in
flash_info->start was a physical address. However, from u-boot's
point of view, and looking at most flash code, it makes more
sense for this to be a virtual address. So I corrected the
comment to indicate that this was a virtual address.
The only flash driver that was actually treating the address
as physical was the mtd/cfi_flash driver. However, this code
was using it inconsistently as it actually directly dereferenced
the "start" element, while it used map_physmem to get a
virtual address in other places. I changed this driver so
that the code which initializes the info->start field calls
map_physmem to get a virtual address, eliminating the need for
further map_physmem calls. The code is now consistent.
The *only* place a physical address should be used is when defining the
flash banks list that is used to initialize the flash_info struct,
usually found in the board config file.
