Commit 8fa7f65dd02c ("configs: Remove am335x_boneblack_defconfig") removes defconfig for BeagleBone Black board, and it's advised to use am335x_evm_defconfig for all AM335x boards. But it's impossible to store environment in eMMC with am335x_evm_defconfig without modifications (NAND must be disabled, MMC enabled, etc). This is inconvenient for user to do such modifications via menuconfig (only developer knows what should be done). Furthermore, enabling MMC options in am335x_evm_defconfig leads to wrong pin-muxing scheme in board/ti/am335x/mux.c, because both NAND and MMC options are enabled in the config, so that pins are muxed for BBB with NAND cape, which in turn leads to non-functioning eMMC. There is no way to make the single defconfig working for both eMMC and NAND use-cases, because we can't figure out in run-time which board configuration is used by user (EVM, BBB, or BBB with NAND cape). Hence we rely on CONFIG options to figure out which configuration is used. Because of this we can't use single defconfig for AM335x EVM and BBB.
All that said, let's bring back am335x_boneblack_defconfig, because right now users are not able to use U-Boot for BBB. Further patch will update this defconfig by enabling Driver Model and pulling some other useful options from am335x_evm_defconfig.
