BootROM and neither SPL does not use eMMC boot acknowledgement or boot

SPL successfully loads u-boot from the same partition as SPL. SD card
and UART continue to boot.
Thanks Pali!

Ok, is something more needed for this patch series?
Unfortunately yes. As at least this board breaks with this patchset
added:
$ make sama5d2_icp_mmc_defconfig
$ make -sj
/opt/kernel.org/gcc-12.2.0-nolibc/arm-linux-gnueabi/bin/arm-linux-gnueabi-ld.bfd:
u-boot-spl section `__u_boot_list' will not fit in region `.sram'
/opt/kernel.org/gcc-12.2.0-nolibc/arm-linux-gnueabi/bin/arm-linux-gnueabi-ld.bfd:
region `.sram' overflowed by 32 bytes
make[1]: *** [scripts/Makefile.spl:527: spl/u-boot-spl] Error 1
make: *** [Makefile:2049: spl/u-boot-spl] Error 2
So CI build fails and I can't send a pull request. I'm sending a patch
though, to fix this image overflow by enabling LTO. Stay tuned...
Thanks,
Stefan
