909878fd3f Blackfin: add os log functions
Part of the mini Blackfin ABI with operating systems is that they can use
0x4f0-0x4f8 to pass log buffers to/from bootloaders.  So add support to
U-Boot for reading the log buffer.

bc0d3296f1 asm-generic: Consolidate errno.h to asm-generic/errno.h
This patch use blackfin errno.h implementation which
correspond Linux kernel one.

MIPS implemetation is different that's why I keep it.

I removed ppc_error_no.h from Marvell boards which
was the same too.

I have got ack from ppc40x, blackfin, arm, coldfire and avr custodians.

f348ab85f7 Blackfin: convert specific pre/post config headers to common method
The Blackfin port was using asm/blackfin-config-{pre,post}.h to setup
common Blackfin board defines.  The common method now is to use config.h,
so convert blackfin-config-post.h to that.  Rename the still Blackfin
specific blackfin-config-pre.h to config-pre.h so the naming conventions
at least line up.

02778f2f1b Blackfin: fix booting with older bootroms (no EVT1)
When dropping jump block support, the assumption was that all bootroms
supported entry point redirection via the EVT1 register.  Unfortunately,
this turned out to be incorrect for the oldest Blackfin parts (BF533-0.2
and older and BF561).  No one really noticed earlier because these parts
usually are booted by bypassing the bootrom entirely, and older BF533
parts are not supported at all (too many anomalies).

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

65e43a1063 Introduce virt_to_phys()
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.

b57ca3e128 Change bd/gd memsize/ram_size to be phys_size_t.
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.
