[U-Boot] [PATCH 0/9] imx: mx6: support LPDDR2 and add mx6slevk spl

[Peng Fan]

This patch set is to support SPL for mx6slevk board.
But mx6slevk features one LPDDR2 chip. Then we need to first add
LPDDR2 SPL support. Also introduce one ddr_type entry to
differentiate DDR3 and LPDDR2. This patch set also correct tRFC and
tXS for DDR3 4Gb chip.

The LPDDR2 part is implemented referencing MX6SL LPDDR2 Script Aid V0.04.xlsx
and JESD209-2E. I am not DDR expert, can not guarantee that this can
achieve production quality. Please review.

Patchset tested boot on mx6sxsabresd revb and mx6slevk board.
