V2: - Drop the tegra_keyboard_init() comment altogether - Immediatelly return from the SD controller probe function on failure - Rename PFUZE100_PMIC to just PFUZE100 - Fix the IMX OTP support with CMD_FUSE - Enabling LVDS clock is still in place, since this is coming soon. V3: - Zap rootpath builtin env V4: - Zap the checkpatch issues - Update comments V5: - Don't configure VGEN1 - Set FPGA into reset in SPL - Drop ECSPI1 and add ECSPI3 mux - Drop UART1 and add UART3, UART4 muxes - Add separate mux option for the RGMII pins which doesn't set SPEED field - Move the configuration of RGMII after they were configured in GPIO mode
