If on your board is more than one flash, you must know
the size of every single flash, for example, for updating
the DTS before booting Linux. So make this function
flash_get_info() extern, and you can have all info
about your flashes.

SOFT_RESET must be asserted for at least 3 TX clocks. Usually, that's about 30
clock cycles, so it's been mostly working. But we had no guarantee, and at
slower bitrates, it's just over a microsecond (over 1000 clock cycles). This
enforces a 2 microsecond gap between assertion and deassertion.

This patch adds the configuration option CONFIG_SYS_SMC_RXBUFLEN.
With this option it is possible to allow the receive
buffer for the SMC on 82xx to be greater then 1. In case
CONFIG_SYS_SMC_RXBUFLEN == 1 this driver works as the
old version.
When defining CONFIG_SYS_SMC_RXBUFLEN also
CONFIG_SYS_MAXIDLE must be defined to setup the maximum
idle timeout for the SMC.

If we call flush_cache(0xfffff000, 0x1000) it would never
terminate the loop since end = 0xffffffff and we'd roll over
our counter from 0xfffffe0 to 0 (assuming a 32-byte cache line)

We have common defines that we duplicate in various ways. Having an
arch specific config.h gives us a common location for those defines.
Eventually we should be able to replace this when we have proper
Kconfig support.

Now that the rest of u-boot can support it, change the PCI bus
address of the PCI MEM regions from 0x80000000 to 0xc0000000,
and use the same bus address for both PCI1 and PCI2. This will
maximize the amount of PCI address space left over to map RAM
on systems with large amounts of memory.

The code assumes that the pci bus address and the virtual
address used to access a region are the same, but they might
not be. Fix this assumption.

Clean up PCI mapping concepts in the 8641 config - rename _BASE
to _BUS, as it's actually a PCI bus address, separate virtual

The BAT fields are architected; there's no need for these to be in
cpu-specific files. Drop the duplication and move these to
include/asm-ppc/mmu.h. Also, remove the BL_xxx defines that were only
used by the alaska board, and switch to using the BATU_BL_xxx defines
used by all the other boards. The BL_ defines previously in use
had to be shifted into the proper position for use, which was inefficient.

It is no longer always true that the pci bus address can be
used as the virtual address for pci accesses. pci_map_bar()
is created to return the virtual address for a pci region.

Because the inbound pci windows are mapped generously, set up
the more specific outbound windows first. This way, when we
search the pci regions for something, we will hit on the more
specific region. This can actually be a problem on systems
with large amounts of RAM.

When we search for an address match in pci_hose_{phys_to_bus,bus_to_phys}
we should give preference to memory regions that aren't system memory.
Its possible that we have over mapped system memory in the regions and
we want to avoid depending on the order of the regions.

The PCI_REGION_MEMORY and PCI_REGION_MEM are a bit to similar and

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
