Seems like SPL (sdc4) at 4th partition and U-Boot proper at first
partition which seems an unconventional way to create partition
layouts based on the booting stage hierarchy.

I did send the changes on top of our changes [1] which indeed follow
the conventional partition layout. So feel free to incorporate your
series while sending the next version.

So from next version, you can drop
CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_USE_PARTITION and write images as,

$ sudo dd if=u-boot.itb of=/dev/sda seek=4096
$ sudo dd if=spl/u-boot-spl.bin of=/dev/sda seek=2048
