This is a conflict I got. This file should be generic code, and should
not have reference to a specific SOC or SOC family, as omap here. So I
have added a include/spl.h with only the SPL relevant part, dropping
other OMAP specific from this file (I see you did the same with
omap_boot_device and omap_boot_mode).

As far as I have understood, this is only for MMCSD_SECTOR_SIZE, that
can be moved into another header file. Not all SOCs have
asm/arch/mmc_host_def.h

Both files are OMAP specific

And this is also omap specific. Replaced by soc_boot_device ?
