[U-Boot] [PATCH v3 2/6] Tegra: MMC: Added/update SDMMC registers/base addresses for T20/T30

Tom Warren
2013-03-07T21:47:54Z

Removed SDMMC base addresses from tegra.h since they're no longer used.
Added additional vendor-specific SD/MMC registers and bus power defines.

Signed-off-by: Tom Warren <twarren@nvidia.com>
---
v2:
- change pad_init_mmc prototype
- remove all TEGRA_SDMMCx_BASE defines
v3:
- remove GP padctrl SDIOCFG defines, done in previous padctrl patch
