---
v4:
- Reuse socfpga_n5x_socdk.dts from Linux and add U-boot specifc dts
to u-boot.dtsi. Linux socfpga_n5x_socdk.dts:
https://github.com/altera-opensource/linux-socfpga/blob/socfpga-5.4.114-lts/arch/arm64/boot/dts/intel/socfpga_n5x_socdk.dts
v3:
- Update comment for memory example code
- Move all common dts settings for N5X from
socfpga_n5x_socdk.dts to socfpga_n5x-u-boot.dtsi
- Remove unused parameter "u-boot,boot0"
v2:
- Remove socfpga_n5x.dtsi
- Reuse socfpga_agilex.dtsi in socfpga_n5x_socdk.dts and update
n5x data accordingly.
