arm: do not force d-cache enable on all boards
c2dd0d45540397704de9b13287417d21049d34c6 added dcache_enable()
to board_init_r(). This enables d-cache for all ARM boards.
As a result some of the arm boards that are not cache-ready
are broken. Revert this change and allow platform code to
take the decision on d-cache enabling.
Also add some documentation for cache usage in ARM.
This patch adds support for software I2C for GONI and Universal C210 reference targets.
It adds support for access to GPIOs by number, not as it is present,
by bank and offset.

ARM: MX51: PLL errata workaround
This is a port of the official PLL errata workaround from Freescale to
mainline u-boot.
The PLL's in the i.MX51 processor can go out of lock due to a metastable
condition in an analog flip-flop when used at high frequencies.
This workaround implements an undocumented feature in the PLL (dither
mode), which causes the effect of this failure to be much lower (in terms
of frequency deviation), avoiding system failure, or at least decreasing
the likelihood of system failure.

mmc: S5P: Support DMA restarts at buffer boundaries
Currently if a DMA buffer straddles a buffer alignment boundary
(512KiB) then the DMA engine will pause and generate a DMA
interrupt. Since the DMA interrupt is not enabled it will hang
the MMC driver.
This patch adds support for restarting the DMA transfer. The
SYSTEM_ADDRESS register contains the next address that would have
been read/written when a boundary is hit. So we can read that
and write it back. The write triggers the resumption of the
transfer.

integrator: convert to new build system
This deletes the integrator split_by_variant.sh script and
defines a number of unique board types for the core modules
that are meaningful to support for the Integrator AP/CP, i.e.
the ones that did not just say "unsupported core module" in
split_by_variant.sh. If more core modules need to be supported
they are easy to add.
We delete all the old cruft in Makefile and MAKEALL that was
working around the old way of building boards. We create a
unique config file per board to satisfy the build system, but
they are just oneliners that include the existing
integratorap.h and integratorcp.h configs.
The default configuration for the Integrator AP forces memory to be
32 MB on the command line to the kernel, while we have perfect
information and detection of the actual memory size in the ATAGs.
Delete the confusion.
This adds support for a subset of the default commands for the
Integrator, however since the card does not have Ethernet (unless
you plug in a PCI card) we can not use the default command set.
The integrator board was apparently never converted over to support
relocation until now. After this the integrator u-boot both compiles
and boots on the Integrator AP.
The integratorap/cp config for u-boot was outdated and would not
even compile, so fix the obvious missing bits for it to start
building. After this "make ap920t_config/make all" starts working
again.
