[U-Boot] [PATCH 0/3] AM437x: Add runtime DTB selection for QSPI Boot

[U-Boot] [PATCH 0/3] AM437x: Add runtime DTB selection for QSPI Boot

[Vignesh R]

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.

[U-Boot] [PATCH 1/3] board: ti: am43xx: Define embedded_dtb_select for runtime DTB selection in U-boot

[Vignesh R]

AM437x QSPI boot is a single stage boot and hence needs runtime DTB
selection to support AM437x-SK and AM437x-IDK with DM enabled. This is
required to move am43xx_evm_qspiboot_defconfig to use DM/DT.

[U-Boot] [PATCH 2/3] ARM: dts: Add new "generic" am4372 device tree file.

[Vignesh R]

With U-boot runtime board detect for DTB selection a "default" dtb needs
to be created. This will be used temporarily until the "proper" dtb is
selected.

Also, add -u-boot.dtsi for AM437x SK and IDK to enable I2C for
board detection via DM_I2C.

[Vignesh R]

Move am43xx_evm_qspiboot_defconfig to DM. This is required as SPI core
and TI QSPI driver no longer supports non DM interfaces.
