It really is, thanks for getting it as far as you did!

Although very mildly disappointed that this might deprioritize making
split /boot in guix a reality. :)

https://www.aikidev.net/~vagrant/guix/u-boot-2022.04-rc5-with-rockpro64-scsi.patch

Pretty similar to what you had already, with some added native-inputs
for the newer u-boot version, minor adjustments to the patch to disable
openssl, and I only tweaked the upstream files in the
u-boot-rockpro64-rk3399 package, not for all u-boot packages. There is
also an unrelated extraneous patch, but I left it out of the above patch
for brevity.

I think it *might* be possible to get the patches a little
smaller... and of course should get submitted upstream!

I'd consider pushing the updates now, but u-boot 2022.04 is planned to
be released monday, so may as well wait till then.


> Are you using a PCIe card with your rockpro64?

Yup. Pretty sure it's whatever PCIe dual-port sata card I bought right
along with the rockpro64.

U-boot is still on microSD, but it loads the kernel+initrd+dtb from
SCSI. The scsi target ends up pretty low in the boot order, so you have
to either manually set the boot_targets or make sure your mmc/nvme
devices aren't bootable (e.g. change partition type, rename boot
extlinux.conf, etc.):

  Hit any key to stop autoboot:  0
  => printenv boot_targets
  boot_targets=mmc1 mmc0 nvme0 scsi0 usb0 pxe dhcp sf0
  => setenv boot_targets scsi0
  => boot
