AM62x boot rom supports booting from eMMC.
Please refer to AM62x TRM "5.4.4 eMMC Boot" for details on eMMC boot support by boot rom.
The FAQ lists how to flash u-boot to eMMC boot partition (either boot0 or boot1) in raw mode using Lauterbach JTAG on SK-AM62 board [1] with AM62x Linux SDK 10.0.7.4 [3]. The scripts would be applicable to flash u-boot to eMMC on SK-AM62A-LP board [2] as well.
