Signed-off-by: Kankan Sun --- Hi Michael, Since this is the first time I've submitted code to the Linux community, please forgive me for some of the missteps that I've made. I uploaded the incorrect patch file. In a previous e-mail you said： XMC parts seem to have SFDP tables and they should work out of the box without any patches with the generic spi nor driver [1]. Therefore, you don't need any entry at all. I think it is related to the PARSE_SFDP flag. The XMC flash part supports SFDP, so i don’t need to add NO_SFDP_FLAGS() macro. drivers/mtd/spi-nor/xmc.c | 17 +++++++++++++---- 1 file changed, 13 insertions(+), 4 deletions(-) diff --git a/drivers/mtd/spi-nor/xmc.c b/drivers/mtd/spi-nor/xmc.c index 051411e86339..e78bf11792d9 100644 --- a/drivers/mtd/spi-nor/xmc.c +++ b/drivers/mtd/spi-nor/xmc.c @@ -11,11 +11,20 @@ static const struct flash_info xmc_nor_parts[] = { /* XMC (Wuhan Xinxin Semiconductor Manufacturing Corp.) */ { "XM25QH64A", INFO(0x207017, 0, 64 * 1024, 128) - NO_SFDP_FLAGS(SECT_4K | SPI_NOR_DUAL_READ | - SPI_NOR_QUAD_READ) }, + PARSE_SFDP }, { "XM25QH128A", INFO(0x207018, 0, 64 * 1024, 256) - NO_SFDP_FLAGS(SECT_4K | SPI_NOR_DUAL_READ | - SPI_NOR_QUAD_READ) }, + PARSE_SFDP }, + { "XM25QH128C", INFO(0x204018, 0, 64 * 1024, 256) + PARSE_SFDP }, + { "XM25QH256C", INFO(0x204019, 0, 64 * 1024, 512) + PARSE_SFDP }, + { "XM25QU256C", INFO(0x204119, 0, 64 * 1024, 512) + PARSE_SFDP }, + { "XM25QH512C", INFO(0x204020, 0, 64 * 1024, 1024) + PARSE_SFDP }, + { "XM25QU512C", INFO(0x204120, 0, 64 * 1024, 1024) + PARSE_SFDP }, + }; const struct spi_nor_manufacturer spi_nor_xmc = { -- 2.34.1 --===============4661509945995069759== Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline ______________________________________________________ Linux MTD discussion mailing list http://lists.infradead.org/mailman/listinfo/linux-mtd/ --===============4661509945995069759==--
