- Re-use i.MX 93 Makefile target as similar boot process
- Create imx8ulp-u-boot.dtsi for binman image architecture
- Create both SPL and U-Boot containers configuration
Key differences between the 93 and 8ULP SPL container are:
- No LPDDR training library needed for 8ULP
- 8ULP requires a uPower binary (RISC-V core) for power management
- 8ULP also requires a M33 binary to work properly
