[PATCH 0/2] Enable serial NOR flash on RZ/G3E SMARC EVK

[PATCH 0/2] Enable serial NOR flash on RZ/G3E SMARC EVK

[Biju Das]

This patch series aims to enable serial NOR flash on RZ/G3E SMARC EVK.

We can flash bootloaders in Linux by executing the below commands:
flash_erase /dev/mtd0  0 0
flash_erase /dev/mtd1  0 0
mtd_debug write /dev/mtd0 0 ${BL2_FILE_SIZE} ${BL2_IMAGE}
mtd_debug write /dev/mtd1 0 ${FIP_FILE_SIZE} ${FIP_IMAGE}

Got it, thanks for info. Sorry for the false positive that the bot currently
can't handle the dependency nicely for such case. I will consider to not report
out this type of dtcheck issue directly if not on next or mainline (to align
with other dtcheck issue).
