Merge patch series "am62dxx-evm: Add SPI flash support"
Paresh Bhagat <[email protected]> says:
This series enables SPI flash support for the AM62DX EVM platform.
The first patch enables the required SPI flash configuration options in
both A53 and R5 defconfigs, including Cadence QSPI driver support, SFDP
support, and Spansion S28HX-T flash compatibility.
The second patch adds the necessary device tree configuration for the R5
SPL to support OSPI flash access during the boot process.
