[U-Boot] [PATCH v2 0/2] AM57xx-IDK: Add QSPI support:wq

[Vignesh R]

This series adds support for QSPI for am571x-idk and am572x-idk. The
flash is same as the one present on DRA74 EVM.

Tested on am572x-idk and am571x-idk.

[U-Boot] [PATCH v2 1/2] ARM: am57xx_evm: Enable QSPI support

[Vignesh R]

AM571x IDK and AM572x IDK EVMs have spansion s25fl256s QSPI flash on the
board connected to TI QSPI IP over CS0. Therefore enable QSPI support.

[U-Boot] [PATCH v2 2/2] ARM: dts: am57xx-idk-common: Enable support for QSPI

[Vignesh R]

AM571x and AM572x IDK have a spansion s25fl256s QSPI flash on the board
connected to TI QSPI over CS0. Hence, add QSPI and flash slave
DT nodes.
