With the stack and text base used by U-Boot SPL and proper on RK3328 and RK3399 there is a high likelihood of overlapping when U-Boot proper + FDT nears 1 MiB in size.
Trying to run U-Boot proper close to 1 MiB in size with debug logging something similar to following can be observed:
FDT 00000000002fc4e0 gd 00000000002fddf0 FDT overlap resetting ... System reset not supported on this platform ### ERROR ### Please RESET the board ###
Fix this by changing stack and bss addresses used on RK3328 and RK3399. The addresses chosen for stack and bss is a combination from both boards.
This series depends on the following two series: - rockchip: rk3328: Update defconfigs, DTs and enable boot from SPI [1] - rockchip: Read cpuid and generate MAC address from efuse for RK3328 and RK3399 [2]
