After determining how much DDR is actually in the system, set DBAT0 and
IBAT0 accordingly. This ensures that the CPU won't attempt to access
(via speculation) addresses outside of actual memory.
On 86xx systems, DBAT0 and IBAT0 (the BATs for DDR) are initialized to 2GB
and kept that way. If the system has less than 2GB of memory (typical for
an MPC8610 HPCD), the CPU may attempt to access this memory during
speculation. The zlib code is notorious for generating such memory reads,
and indeed on the MPC8610, uncompressing the Linux kernel causes a machine
check (without this patch).
Currently we are limited to power of two sized DDR since we only use a
single bat. If a non-power of two size is used that is less than
CONFIG_MAX_MEM_MAPPED u-boot will crash.

Use the same code between primary and secondary cores to init the
L1 cache. We were not enabling cache parity on the secondary cores.
Also, reworked the L1 cache init code to match the e500mc L2 init code
that first invalidates the cache and locks. Than enables the cache and
makes sure its enabled before continuing.

440EPx fixed bootstrap options A, B, D, and E sets PLL FWDVA to a value = 1.
This results in the PLLOUTB being greater than the CPU clock frequency
resulting unstable 440EPx operation resulting in various software hang
conditions.
This patch reprograms the FWDVA satisfying the requirement of setting FWDVB
to a value greater than 1 while using one of the four deafult bootstrap options.

The soft-i2c code for AT91 defines I2C_SOFT_DECLARATIONS
for direct access by dereferencing a pio pointer.
The OTC570 platform uses the AT91 gpio API so it does not
need the pio variable.

The patch removes warnings at compile time and provides
some cleanup code:
- Removed comment on NAND (not yet supported) from lowlevel_init.S
- Removed NFMS bit definition from imx-regs.h
The bit is only related to MX.25/35 and can lead to confusion
- Moved is_soc_rev() to soc specific code (removed from mx51evk.c)

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.
