[U-Boot] [PATCH 0/7] Exynos4412 SPL support

[Simon Shields]

Hi,

This patch series adds support for using U-Boot's SPL as the second
stage bootloader ("BL2") on Exynos4412 SoCs.

- Patch #1 adds support for the EMMC/SD OM pin configuration, which is used
  by the boards I tested on.
- Patch #2 configures the magic values used to indicate system suspend
  state (which are identical to exynos5).
- Patch #3 renames the existing exynos4 clock/dmc initialisation code
  to reflect the fact that it only supports exynos4210.
- Patches #4 and #5 add/fill in structs reflecting the PMU and TZASC
  register layouts on exynos4412, respectively.
- Patch #6 adds the exynos4412 DMC and clock initialisation code and
  enables building the SPL on exynos4412 platforms.
- Patch #7 enables building the "mkexynosspl" utility for exynos4 SoCs.

The majority of the logic in patch #6 comes from a vendor u-boot dump
(2010.12!), however, small portions (mostly code used for 2GB RAM
initialisation) were reverse engineered from the vendor
bootloader found on a GT-N7100.

This patch series has been tested on a GT-I9300 (exynos4412, 1GB RAM)
and a GT-N7100 (exynos4412 prime, 2GB RAM), with a few additional
patchsets applied for board/HW support (which I intend to upstream in
the future).

Cheers,
Simon
