Draft: u-boot on emmc and /boot on sata
- u-boot-config: enable CONFIG_SATA_BOOT
- patches/0001-tweak-boot-commands.patch: also attempt booting from sata0
- build u-boot image for sd as well as for emmc
- switch to POSIX shell
- set -u
- make shellcheck clean
- avoid cd in favour of -C and env --chdir
- bump u-boot version from v2023.10-rc4 to v2023.10
- verify top git hashes for u-boot and atf
- verify that BPI Block Copy src is correct for sd and emmc
- verify that sd and emmc images differ only in the Block Copy src
marked as draft as we first have to test whether this works
