Blackfin: use scratch pad for exception stack
If the memory layout pushes the stack out of the default DCPLB coverage,
the exception handler may trigger a double fault by trying to push onto
the uncovered stack. So handle the exception stack similar to the kernel
by using the top of the scratch pad SRAM.

Blackfin: change global data register from P5 to P3
Since the Blackfin ABI favors higher scratch registers by default, use the
last scratch register (P3) for global data rather than the first (P5).
This allows the compiler's register allocator to use higher number scratch
P registers, which in turn better matches the Blackfin instruction set,
which reduces the size of U-Boot by more than 1024 bytes...

OMAP3 Move cache routine to cache.S

Collect the other omap cache routines l2_cache_enable and
l2_cache_disable with invalide_dcache into cache.S. This
means removing the old cache.c file that contained l2_cache_enable

The conversion from cache.c to cache.S was done most through
disassembling the uboot binary. The only significant change was
to change the comparision for the return of get_cpu_rev from

arm: Kirkwood: add SYSRSTn Duration Counter Support
This feature can be used to trigger special command "sysrstcmd" using
reset key long press event and environment variable "sysrstdelay" is set
(useful for reset to factory or manufacturing mode execution)
Kirkwood SoC implements a hardware-based SYSRSTn duration counter.
When SYSRSTn is asserted low, a SYSRSTn duration counter is running.
The counter value is stored in the SYSRSTn Length Counter Register
The counter is based on the 25-MHz reference clock (40ns)
It is a 29-bit counter, yielding a maximum counting duration of
2^29/25 MHz (21.4 seconds). When the counter reach its maximum value,
it remains at this value until counter reset is triggered by setting
bit 31 of KW_REG_SYSRST_CNT
Implementation:
Upon long reset assertion (> ${sysrstdelay} in secs) sysrstcmd will be
executed if pre-defined in environment variables.
This feature will be disabled if "sysrstdelay" variable is unset.

>4G of memory as we know can't access all of memory and we need to

to map as much of memory as possible.
On PCIe based controllers we are able to overmap the ATMU setup since

On PCI based controllers we use as many inbound windows as available to
