The S25FL256L is a part of the S25FL-L family and has the same feature set as S25FL128L except the density.
The datasheet can be found in the following link. https://www.cypress.com/file/316171/download
The S25FL256L is 32MB NOR Flash that does not support Bank Address Register. This fixup is activated if CONFIG_SPI_FLASH_BAR is enabled and returns ENOTSUPP in setup() hook to avoid further ops.
Tested on Xilinx Zynq-7000 FPGA board.
Signed-off-by: Takahiro Kuwano Takahiro.Kuwano@infineon.com --- Changes in v2: - Merge separated patches into one - Remove #ifdef CONFIG_SPI_FLASH_BAR
