[PATCH 0/4] mtd: spi-nor-core: Track flash's internal address mode in s25hx-t

[tkuw584924 at gmail.com]

From: Takahiro Kuwano <Takahiro.Kuwano at infineon.com>

For S25hx-T support in Linux (single die package only), flash's internal
address mode is not changed and it is assumed as factory default. Current
implementation of u-boot forces to 4-byte address mode while some parts
are 3-byte address mode by default. That will cause a problem when we use
u-boot to load the Linux kernel. This series tries to avoid the problem,
by porting two changes from linux [0][1] and additional rework.
