[U-Boot] [PATCH 0/9] Add basic Tegra30 (T30) support
This patch series adds basic (boot to cmd prompt) support for Tegra30.
This is based on the Tegra20 SPL, which initializes the AVP (ARM7TDMI
boot proc) first, then control is transferred to the CPU (A9 quad cluster).
It is based on current u-boot-tegra/next.
Future patches will add support/drivers for MMC, USB, I2C, SPI, NAND,
and other peripherals. The Cardhu T30 board is supported initially.
Tom Warren (9):
Tegra: T30: Add include files
Tegra: T30: Add AVP (arm720t) files
Tegra: T30: Add CPU (armv7) files
Tegra: T30: Add common Tegra30 CPU files
Tegra: DT: Add preliminary device tree files for T30 Cardhu
Tegra30: Add Cardhu board files
Tegra30: Add config files (common and Cardhu)
Tegra30: Add common pinmux config in board_early_init_f
Tegra30: Enable Cardhu build (SPL)
