I'm working on a project to bring mainline linux kernels to android phones.
I'm planning to use u-boot as a secondary stage bootloader packed in
android boot image,
so that linux kernel is replaced with u-boot, and initramfs is replaced
with FIT image.
This approach allows to use u-boot on a phone without much pain with
storage drivers.
Obviously, u-boot should know initramfs load address. It can be obtained
from initrd-start
device tree option. However, on arm64 address to the right device tree is
provided in x0 CPU
register.
Would you accept a patch to preserve boot args on arm64?

Seems like this is already supported with save_boot_params function
