With SPI framework moving to DM only mode, am437x QSPI XIP boot needs to
move to runtime DTB selection to chose proper DT for IDK vs SK. This
series adds generic DT file for board detection which is replaced with
actual DT once after board discovery via EEPROM. Approach is similar
to what is done with K2G EVM.

Tested on AM437x SK and IDK boards. Sanity tested on AM437x GP EVM.

Vignesh R (3):
  board: ti: am43xx: Define embedded_dtb_select for runtime DTB
    selection in U-boot
  ARM: dts: Add new "generic" am4372 device tree file.
  configs: am43xx_evm_qspiboot_defconfig: Move to DM
