Boot configuration stored in EXT_CSC register is completely ignored by BootROM: https://lore.kernel.org/u-boot/CAOAjy5SYPPzWKok-BSGYwZwcKOQt_aZPgh6FTbrFd3F=...
Reflect this eMMC booting in documentation and in the code.
Martin, can you test this patch series if SPL and main U-Boot is loaded from the same eMMC HW partition?
When bootloader is stored on Boot 0, then SPL should take care of loading and executing main U-Boot. When it is stored on Boot 1 or User Data then SPL should return back to BootROM and let BootROM to load and execute main U-Boot.
