From de76ae36f622177e9af38b158d7f2f753d826d2c Mon Sep 17 00:00:00 2001 From: Su Baocheng Date: Mon, 25 Jan 2021 10:59:05 +0800 Subject: [PATCH] mtd: spi-nor-ids: Add support of flash protection to w25q128 The NOR flash w25q128 denoted by JEDEC ID 0xef4018 actually represents various models. From Winbond's website, I could only find 3 types of them: W25Q128JV-IQ/JQ datasheet:https://www.winbond.com/resource-files/ w25q128jv%20revg%2004082019%20plus.pdf W25Q128FV (SPI Mode) datasheet: https://www.winbond.com/resource-files/ w25q128fv%20rev.m%2005132016%20kms.pdf W25Q128BV datesheet: https://www.winbond.com/resource-files/ w25q128bv_revh_100313_wo_automotive.pdf According to the datasheets, all of these 3 types support BP(0,1,2) and TB bits in the status register (SR), so it could reuse the flash protection logic for ST Micro. So it should be safe to add the SPI_NOR_HAS_LOCK and SPI_NOR_HAS_TB flags to the w25q128 entry of spi_nor_ids table.
