When verify boot is not enabled, the all images load addr
is determined by U-Boot xxx_addr_r definitions, that's fine
without this patch.
But when verify boot is enabled and kernel load/entry addr
in signed boot.img is mismatch with U-Boot "kernel_addr_r",
the kernel relocation action will memcpy ram data from
"kernel_addr_r" to the kernel load/entry addr, because U-Boot
assumes the kernel is already in "kernel_addr_r" before now.
Thus, the kernel is corrupted and cause a jump abort.
This issue was found in rk3568: use high version U-Boot
(kernel_addr_r is 0x280000) to verify boot low version
signed boot.img(kernel load/entry is 0xa80000).
All this is due to commit:
(ee6a3c94a5 rockchip: rk3568: Update "kernel_addr_r" as 0x00280000)
