Thanks for your patch!
Blindly removing config options from defconfig files that haven't
received much love for a while is IMHO not such a good idea, as it makes
it harder to see what the affected platform needs, or needed.

MTD_SPI_NOR became a dependency for MTD_M25P80 since commit
03e296f613affcc2671c1e86d8c25ecad867204e ("mtd: m25p80: use the SPI nor
framework") and commit e43b20619bdb6c851dd7b49cbd15e52875a785d4 ("mtd:
spi-nor: shorten Kconfig naming"). Hence CONFIG_MTD_SPI_NOR=y should be
added to avoid breaking the platform's SPI FLASH support.
Just removing CONFIG_MTD_M25P80=y from the defconfig makes this less
visible for someone who wants to build a kernel for this platform using
"make sh7757lcr_defconfig": it can no longer be seen that
CONFIG_MTD_M25P80=y won't be present in the resulting .config file.
I think the platform would be better served with a proper refresh of the
defconfig file.
