Add CONFIG_{SD|NOR|NAND|ONENAND|SPI|QSPI|SATA}_BOOT kconfig entries.
SoCs supports loading U-Boot from different medias to DRAM, such as
i.MX6/7 supports loading U-Boot to DRAM from sd/emmc/nand/qspi/spi/sata
and etc. For i.MX, imximage will generate different IVT headers according
to boot medias.

Hmm... are there no places where the introduced config options
already used in config files ?

For example this is already defined in

So I miss at least the lines, which remove this part in your patch,
else I think, this would lead in a Kconfig error, if we have the
same symbol in two places ... or?

may you want to use my brand new tbot testcase [1] for testing, if your
patch not breaks boards?
