[U-Boot] [PATCH] arm: am57xx: Keep environment in eMMC
Use eMMC (instead of SD card) to store U-Boot environment. Use "reserved" partition for U-Boot environment.

This is exactly how it's done for DRA7 EVM board. And since those two boards are basically the same family, we should stick to one way of doing things here. And we agreed with Praneeth that this policy is booting Android from eMMC.

Right, but Android isn't the only use-case here. If Lokesh acks it, I'm fine with it. But, to be clear, are there am57xx_evm targets that lack eMMC? I don't want to get into the case we used to have on am335x_evm where we assume NAND for env, and run on many targets without NAND.

No, I don't think so. All AM57x EVM / X15 boards I've seen up to this point do have eMMC on board. So there shouldn't be any problems here.

Yeah, I really like to keep env in FAT partition but because of android usecases we will have to keep it in eMMC(I am still trying to find a strong reason for not using it in eMMC and stick to FAT ;) ). As of now, all am57x boards(am572-evm, beagle-x15, am572-idk, am571-idk has eMMC.)
