Some Freescale's processors of different architecture
have the same peripheral (eSDHC controller in PowerPC
and i.MX51). This patch adds accessors for
the internal registers of the SOCs, as already
implemented in the PowerPC architecture.

Most controllers can check if there is a card in the slot.
However, they require pins that could be not available because
required by other functions and the detection of a card must
be performed in another way. This patch adds a weak function
that a board can implement to add its internal custom way
to check the presence of a MMC/SD card.

Most cards do not answer if some reserved bits
in the ocr are set. However, some controllers

725233: PLD instructions executed with PLD data forwarding
enabled can result in a processor deadlock
This deadlock can happen when NEON load instructions are used together
with cache preload instructions (PLD). The problematic conditions
can be triggered in-the-wild by NEON optimized functions from pixman
library (http://cgit.freedesktop.org/pixman), which perform dynamic
adjustment of prefetch distance.
The workaround disables PLD data forwarding by setting PLD_FWD bit
in L2 Cache Auxiliary Control Register as recommended in ARM Cortex-A8
errata list.
The deadlock can only happen on r1pX revisions of Cortex-A8 (used in
OMAP34xx/OMAP35xx). Performance impact of the workaround is practically
non-existant.

commit 2e95004deb "mpc83xx: Add NAND boot support
for MPC8315E-RDB boards" symlinked nand_spl/board/freescale/mpc8315erdb to
mpc8313erdb in order to not duplicate code.
Since the main makefile builds nand_spl/board/$(BOARDDIR) (which makes sense),
and the board Makefile and linker script are the only two necessary files
to enable out-of-tree building, and other boards have duplicated nand makefiles
(e.g. 8536ds & 8569mds), it only seems prudent to copy these two files in the
name of the 8315 too.
