Hey folks,

As part of converting outstanding CONFIG symbols to Kconfig, I've run in to CONFIG_SPL_BOOT_DEVICE and while I think I see how to do it, it would be better I think if someone that has the hardware and can test the logic out, does it.

In short, I believe we need to:

• SPL_BOOT_SPI_NOR_FLASH / SPL_BOOT_SDIO_MMC_CARD become a choice section in arch/arm/mach-mvebu/Kconfig, guarded by !SECURED_MODE_IMAGE
• KWB_CFG_SEC_BOOT_DEV in arch/arm/mach-mvebu/Makefile gets updated based on how the Kconfig logic now works.
• In the case of CONFIG_SPL_BOOT_SDIO_MMC_CARD (or whatever it's named) and MMC_SDHCI we just have that value defined and drivers/mmc/sdhci.c is updated to check it for SPL. Or if this is possibly useful outside of SPL, we make use of CONFIG_VAL and have 'SPL_FIXED_SDHCI_ALIGNED_BUFFER' be set for the current case.
• CONFIG_SPL_BOOT_DEVICE is removed

I think that covers everything, but please let me know if I missed something or I got the logic wrong or something. Thanks!

I can give it a go. All the boards I have access to boot from SPI but I can at least compile test the MMC support.

Thanks!
