with arm-trusted-firmware!1 (merged) this builds a working uboot for the devktit for me.
Will unwip once
tested on the phone
i can add ci (depends on atf MR, see below)
his allows to update from userspace via
DEB_BUILD_PROFILES="pkg.uboot.subarch.imx" dpkg-buildpackage -uc -us -B --host-arch=arm64
I can't add CI before arm-trusted-firmware!1 (merged) is merged.
