Getting a truncate error similar to https://github.com/SecKatie/u-boot-rockchip/issues/1

Notwithstanding that truncate error, if I am to follow with how alpine does it, I should try to use the upstream u-boot if possible, and build arm-trusted-firmware for rk3588, following rk3399.

According to https://gitlab.collabora.com/hardware-enablement/rockchip-3588/notes-for-rockchip-3588/-/blob/main/upstream_uboot.md, rk3588 support is upstreamed, so it'll probablt a question of patching in the defconfig.

That said, I should try to get the rockchip version built first so I have a control.

rk3588 is indeed supported by arm-trusted-firmware: https://review.trustedfirmware.org/c/TF-A/trusted-firmware-a/+/21840 (https://www.collabora.com/news-and-blog/blog/2024/02/21/almost-a-fully-open-source-boot-chain-for-rockchips-rk3588/)

Once I want to bring up mainline, I can base the package on https://gitlab.collabora.com/hardware-enablement/rockchip-3588/debian-image-recipes

Got arm-trusted-firmware updated: https://gitlab.alpinelinux.org/alpine/aports/-/merge_requests/84545

Also looks like I'm getting u-boot-radxa-cm5 to a good place. This ressource was really helpful, as I couldn't figure out how to build the itb and itbloader file: https://opensource.rock-chips.com/wiki_Boot_option

Okay, getting somewhere. The boot process is stuck but at least a first step works!

(stuck with one line in serial: U-Boot TPL 2017.09...)

Got u-boot to a place where it goes through 3.1. Issue is with booting the kernel now:

No misc partition
"Synchronous Abort" handler, esr 0x96000010

* Reason:        Exception from a Data abort, from current exception level
....

This fails whether we use the debian kernel or alpine kernel.

It might be the case that u-boot is just to damn old. It might be a good idea to reflash the debian image, and upgrade u-boot to a newer version, and see if it works. An up-to-date branch: https://gitlab.collabora.com/hardware-enablement/rockchip-3588/u-boot
