There was already a command to show the processor clocks
for PowerPC (clocks). For i.MX, the "clockinfo" command
was introduce. The patch sets the same command name used on
PowerPC.
A nasty and not needed newline is also dropped in the help for
the command.

Updated mx53 ddr3 script in order to align with the latest Freescale version from July 8, 2011:
-change ESDREF[REF_SEL]=01 (for 32KHz), from incorrect setting of 00 (64KHz)
-change DDR3 MR0 write to "setmem /32 0x63fd901c = 0x052080b0" from
"0x092080b0". This changes write recovery from 8 clocks to 6 clocks
(in line with ESDCFG1[tWR])

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.

Using mkimage with e.g.

tools/mkimage -A arm -T firmware -O u-boot -d u-boot.bin foo.img

gives a warning

"Unknown OMAP image type - 5"

while it seems that the image itself is created successfully.

This does come from the patch "mkimage: Add OMAP boot image support".

The method check_image_type in image_type_params is supposed to just
return success or failure.  However, for omap it also calls fprintf:

static int omapimage_check_image_types(uint8_t type)
{
	if (type == IH_TYPE_OMAPIMAGE)
		return EXIT_SUCCESS;
	else {
		fprintf(stderr, "Unknown OMAP image type - %x", type);
		return EXIT_FAILURE;
	}
}

All the other image checkers and no others have this, so the fix is to
simply remove the fprintf.

This change is driven by need of general gpio_* functions,

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.

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.
