We are now using an env_ prefix for environment functions. Rename these

Quite a few places use getenv() in a condition context, provoking a
warning from checkpatch. These are fixed up in this patch also.

ARM: k2g: Define embedded_dtb_select for runtime DTB selection in U-boot

For K2G, runtime DTB selection utilizes the embedded_dtb_select function.
Therefore, define the function which will perform a EEPROM read and then
retries selecting the correct dtb now that it can detect which board its
on. For other Keystone devices use an empty function since they will still
use the embedded FIT functionality but their FIT will only contain a single
dtb.

Most production K2G boards do not have their EEPROM programmed. Therefore,
perform a test to verify a K2G GP is currently being used and if it is then
set the values normally set by a EEPROM read.

ARM: keystone2: use detected ddr3a size

Because KS2 u-boot works in 32 bit address space the existing ram_size
global data field cannot be used. The maximum, which the get_ram_size()
can detect is 2GB only. The ft_board_setup() needs the actual ddr3 size
to fix up dtb.

This commit introduces the ddr3_get_size() which uses SPD data to
calculate the ddr3 size. This function replaces the "ddr3_size"
environment variable, which was used to get the SODIMM size.

For platforms, which don't have SODIMM with SPD and ddr3 is populated to
a board a simple ddr3_get_size function that returns ddr3 size has to be
implemented. See hardware-k2l.h

fdt: Allow ft_board_setup() to report failure

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.

keystone2: ecc: add ddr3 error detection and correction support

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.
