The MPC5200 has a nasty problem that will cause silent data corruption
when performing unaligned 16 or 32 byte accesses when reading from the
local bus - typically this affects reading from flash. The problem can
be easily shown:

This commit implements a workaround at least for the most blatant
problem: using memcpy() from NOR flash. We rename the assembler
routine into __memcpy() and provide a wrapper, which will use a
byte-wise copy loop for unaligned source or target addresses when
reading from NOR flash, and branch to the optimized __memcpy()
in all other cases, thus minimizing the performance impact.
Tested on lite5200b and TQM5200S.

The ARM ABI requires that the stack be aligned to 8 bytes as it is noted
in Procedure Call Standard for the ARM Architecture:

The following restructuring and optimisations increase the SPI
read performance from 1.3MiB/s (on da850) to 2.87MiB/s (on da830):
Remove continual revaluation of driver state from the core of the
copy loop. State can not change during the copy loop, so it is
possible to move these evaluations to before the copy loop.
Cost is more code space as loop variants are required for each set
of possible configurations. The loops are simpler however, so the
extra is only 128bytes on da830 with CONFIG_SPI_HALF_DUPLEX
defined.
Unrolling the first copy loop iteration allows the TX buffer to be
pre-loaded reducing SPI clock starvation.
Unrolling the last copy loop iteration removes testing for the
final loop iteration every time round the loop.
Using the RX buffer empty flag as a transfer throttle allows the
assumption that it is always safe to write to the TX buffer, so
polling of TX buffer full flag can be removed.

Currently EMAC_MDIO_PHY_NUM is defined as 1 in emac_defs.h.
Because of this, EMAC does not work on EVMs which do not have phy
connected at 1. Moving the macro to board config file makes this
configurable depending on where the phy is connected on the MDIO bus.
This patch fixes the board reset issue observed during network access
on DM365EVM. EMAC driver was assuming EMAC_MDIO_PHY_NUM as 1
but it is 0 on DM365EVM.
This patch is verified on da830/omap-l137, dm365 and dm644x evms.

Instead of adding explicit build rules for each and every board to the
top level Makefile (which makes it grow and grow), we now provide a
simple default rule and extend the "mkconfig" script to read board
configurations from a plain text file (table), "boards.cfg".
For simple boards it is now sufficient to add a single line of text to
the "boards.cfg" file, no changes to the top level Makefile are needed
any more.
To make the table better readable, change the notation for unused
fields from "NULL" into "-".

Part of this patch is by: Mikhail Kshevetskiy.
Stack must be aligned to 8 bytes on PXA (possibly all armv5te) for LDRD/STRD
instructions. In case LDRD/STRD is issued on an unaligned address, the behaviour
is undefined.
The issue was observed when working with the NAND code, which was rendered
disfunctional. Also, the vsprintf() function had serious problems with printing
64bit wide long longs. After aligning the stack, this wrong behaviour is no
longer present.
