In general, yay. But some specific comments that I know you inherited:

Do you really have to support ATAGS and FDT? Just confirming.

With CONFIG_CMD_FS_GENERIC and CMD_EXT4 do you really need CMD_EXT2 set?

You're setting the config options to get an easy run-time way to set fdtfile but not providing a script command to set it nor a C function. If you don't need run-time detection, just set fdtfile :)

The comment is wrong, and you can do any of: - Opt-out of mtest (and see Wolfgang's readme on why that's probably a good idea) - Correct this to be all of RAM, minus a bit for a reasonably-sized U-Boot to be running in.

Setting aside such a large space for U-Boot is something else you inherited, do you want to re-evaluate this or too late?
+#define CONFIG_SPL_NET_SUPPORT +#define CONFIG_SPL_NET_VCI_STRING "AM335x U-Boot SPL" +#define CONFIG_SPL_ETH_SUPPORT
Keeping in mind the errata involved, does your board support CPSW SPL without needed the erratad-out mode?
