From: Takahiro Kuwano <takahiro.kuw...@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.
