KS2 ddr3 initialization uses ddr3_size global variable before u-boot
relocation. Even if the variable is not being used after relocation,
writing to it corrupts relocation table.
This patch removes the global ddr3_size variable and uses local one
instead.

The value in SDRAM_REF_CTRL controls the delay time between
the initial rising edge of DDR_RESETn to rising edge of DDR_CKE
(JEDEC specs this as 500us). In order to achieve this, SDRAM_REF_CTRL
should be written with a value corresponding to 500us delay before
starting DDR initialization sequence, and configure proper
value at the end of sequence.

Switch to using hardware leveling for certain parameters on the EMIF
rather than using precalculated values. Doing this also means we have a
common place now between am437x and am335x for setting
emif_sdram_ref_ctrl with a value for the correct delay length.

So, to maintain support for newer DDR used in Panda ES rev B3, we

Boards using the TWL4030 regulator may not all use the LDOs the same way
(e.g. MMC2 power can be controlled by another LDO than VMMC2).
This delegates TWL4030 MMC power initializations to board-specific functions,
that may still call twl4030_power_mmc_init for the default behavior.

This function can fail if the device tree runs out of space. Rather than
silently booting with an incomplete device tree, allow the failure to be
detected.
Unfortunately this involves changing a lot of places in the code. I have
not changed behvaiour to return an error where one is not currently
returned, to avoid unexpected breakage.
Eventually it would be nice to allow boards to register functions to be
called to update the device tree. This would avoid all the many functions
to do this. However it's not clear yet if this should be done using driver
model or with a linker list. This work is left for later.

This patch adds the DDR3 ECC support to enable ECC in the DDR3
EMIF controller for Keystone II devices.
By default, ECC will only be enabled if RMW is supported in the
DDR EMIF controller. The entire DDR memory will be scrubbed to
zero using an EDMA channel after ECC is enabled and before
u-boot is re-located to DDR memory.
An ecc_test environment variable is added for ECC testing.
If ecc_test is set to 0, a detection of 2-bit error will reset
the device, if ecc_test is set to 1, 2-bit error detection
will not reset the device, user can still boot the kernel to
check the ECC error handling in kernel.

Patman spits lots of "Invalid MAINTAINERS address: '-'"
error messages for patches with global changes.
It takes too long for Patman to process them.

Rather, it is just like a place holder in case of assigning

The "S: Orphan" in MAINTAINERS means that the maintainer in the

"boards.cfg: move boards with invalid emails to Orphan")
For patch files adding global changes, scripts/get_maintainer.pl
adds bunch of such invalid email addresses, which results in
tons of annoying bounce emails.
