* Revert "generic: 5.4: Add 4B_OPCODES flag to w25q256"Chuanhong Guo2020-04-051-27/+0
| | | | | | | | | | | This reverts commit d7f21940bcaf70ba404d354c7fa6519c1717d00a. Winbond W25Q256FV and W25Q256JV both uses 0xef4019 as JEDEC ID, but only the latter has proper 4B_OPCODES support. W25Q256FV has all 4B read instructions but it lacks a 4B page program instruction, causing the entire flash to be read-only. Signed-off-by: Chuanhong Guo <gch981213@gmail.com>

This patch backports the upstream patch that adds the 4B_OPCODES flag to w25q256 under 5.4 kernel. This is needed for ipq40xx and ramips. Signed-off-by: Robert Marko <robimarko@gmail.com>
