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.

Take the cache flush functions from the kernel as they use hardware loops in
order to get optimal performance.

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.

Our dcache invalidate function doesn't just invalidate, it also flushes.
So rename the function accordingly and fix the dma_memcpy() function so it
doesn't inadvertently corrupt the data destination.

virt_to_phys() returns the physical address given a virtual. In most
cases this will be just the input value as the vast majority of
systems run in a 1:1 mode.
However in systems that are not running this way it should report the
physical address or ~0 if no mapping exists for the given virtual
address.

Added new CONFIG_DISABLE_CONSOLE define and GD_FLG_DISABLE_CONSOLE.
When CONFIG_DISABLE_CONSOLE is defined, setting
GD_FLG_DISABLE_CONSOLE disables all console input and output.

Currently, both are defined as an unsigned long, but
should be phys_size_t. This should result in no real change,
since phys_size_t is currently an unsigned long for all the
default configs. Also add print_lnum to cmd_bdinfo to deal
with the potentially wider memsize.

This commit gets rid of a huge amount of silly white-space issues.
Especially, all sequences of SPACEs followed by TAB characters get
removed (unless they appear in print statements).
Also remove all embedded "vim:" and "vi:" statements which hide
indentation problems.

This way we become able to utilize the full post_log_word for POST
activities (overwise, POST ECC, which has 0x8000 ID, could be
erroneously treated as started in post_output_backlog() even if there
was actually no POST ECC run (because of OCM POST failure, for
example).

All of the duplicated code for Blackfin processors and boot modes have been
unified. After all, the core is the same for all processors, just the
peripheral set differs (which gets handled in the drivers).

Remove the __STRICT_ANSI__ check from the __u64/__s64 declaration on
32bit targets.
GCC can be made to warn about usage of long long types with ISO C90
(-ansi), but only with -pedantic. You can write this in a way that even
then it doesn't cause warnings, namely by:
#ifdef __GNUC__
__extension__ typedef __signed__ long long __s64;
__extension__ typedef unsigned long long __u64;
#endif
The __extension__ keyword in front of this switches off any pedantic
warnings for this expression.

map_physmem() returns a virtual address which can be used to access a
given physical address without involving the cache. unmap_physmem()
should be called when the virtual address returned by map_physmem() is
no longer needed.
This patch adds a stub implementation which simply returns the
physical address cast to a uchar * for all architectures except AVR32,
which converts the physical address to an uncached virtual mapping.
unmap_physmem() is a no-op on all architectures, but if any
architecture needs to do such mappings through the TLB, this is the
hook where those TLB entries can be invalidated.

Some CPUs like PPC, BLACKFIN need sync() to ensure cfi flash write command
is fully finished. The sync() is defined in each CPU's io.h file. For
those CPUs which do not need sync for now, a dummy sync() is defined in
their io.h as well.
