Thanks, I will drop it in v3. > Presumably the BootROM does configure all of the above? Mostly. The boot straps select SD, eMMC, SPI NOR or NAND, and the BootROM loads the SPL from there, so the SPL needs the same controllers and the clock and reset controllers behind them. The BootROM also prints to the console UART. i2c8 is different. The BootROM does not touch the PMIC, but the SPL has to set the PMIC regulators over i2c8 before it can bring up DRAM. I will give that as the reason in v3 instead of the U-Boot sentence. The BootROM can also load the SPL over USB fastboot. I left USB out of this series and can add it in a follow-up. Thanks for the review. Hung-Chun
