Subject: Save bootargs from 1st stage bootloader like linux does
Date: Mon, 10 Jan 2022 18:01:08 +0300	[thread overview]
Message-ID: <CABTCjFCrd7uM-bgjA5Q9tgeCNJKyHCq0DvCMKDd4aFxW-BYu2Q@mail.gmail.com> (raw)

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?
