The RD_SAMPLE_DELAY field is 5 bits so it needs to be masked with 0x1f
instead of 0xf. Rather than checking the read sample delay for all DDR
chip selects use the values for the chip selects that are actually
configured. Finally continue searching for the max_phase value even if the
current read_sample is the same as the max_read_sample.

This patch adds the DDR3 setup and training code taken from the Marvell
U-Boot repository. This code used to be included as a binary (bin_hdr)
into the Armada A38x boot image. Not linked with the main U-Boot. With this
code addition and the serdes/PHY setup code, the Armada A38x support
in mainline U-Boot is finally self-contained. So the complete image
for booting can be built from mainline U-Boot. Without any additional
external inclusion.
Note:
This code has undergone many hours (days!) of coding-style cleanup and
refactoring. It still is not checkpatch clean though, I'm afraid. As the
factoring of the code has so many levels of indentation that many lines
are longer than 80 chars.
