X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=73159af02d023d01d9c4c08d319eb86cb10f1983;p=thirdparty%2Fu-boot.git

rockchip: rock5b-rk3588: Add support for Radxa ROCK 5T

Include the FDT for Radxa ROCK 5T in the FIT, in addition to those for
5B and 5B+, and add board selection code to load the 5T FDT when the
DRAM type is LPDDR5 and ADC channel 5 value is close to 1016.
