Add MT35XU512ABA1G12 parameters to NOR flash parameters array. Since the manufactory ID is changed to 0x2C, add it for micron and using it for relevant settings.
The MT35XU512ABA1G12 only supports 1 bit mode and 8 bits. It can't support dual and quad. Supports subsector erase with 4KB granularity, have support of FSR(flag status register) and flash size is 64MB. --- drivers/mtd/spi/sf_internal.h | 1 + drivers/mtd/spi/spi_flash.c | 2 ++ drivers/mtd/spi/spi_flash_ids.c | 1 + 3 files changed, 4 insertions(+) diff --git a/drivers/mtd/spi/sf_internal.h b/drivers/mtd/spi/sf_internal.h index 839cdbe..f46cb3a 100644 --- a/drivers/mtd/spi/sf_internal.h +++ b/drivers/mtd/spi/sf_internal.h @@ -33,6 +33,7 @@ enum spi_nor_option_flags { /* CFI Manufacture ID's */ #define SPI_FLASH_CFI_MFR_SPANSION 0x01 #define SPI_FLASH_CFI_MFR_STMICRO 0x20 +#define SPI_FLASH_CFI_MFR_MICRON 0x2C #define SPI_FLASH_CFI_MFR_MACRONIX 0xc2 #define SPI_FLASH_CFI_MFR_SST 0xbf #define SPI_FLASH_CFI_MFR_WINBOND 0xef diff --git a/drivers/mtd/spi/spi_flash.c b/drivers/mtd/spi/spi_flash.c index 0034a28..23b8adf 100644 --- a/drivers/mtd/spi/spi_flash.c +++ b/drivers/mtd/spi/spi_flash.c @@ -903,6 +903,7 @@ static int set_quad_mode(struct spi_flash *flash, #endif #ifdef CONFIG_SPI_FLASH_STMICRO case SPI_FLASH_CFI_MFR_STMICRO: + case SPI_FLASH_CFI_MFR_MICRON: debug("SF: QEB is volatile for %02x flash\n", JEDEC_MFR(info)); return 0; #endif @@ -976,6 +977,7 @@ int spi_flash_scan(struct spi_flash *flash) #if defined(CONFIG_SPI_FLASH_STMICRO) || defined(CONFIG_SPI_FLASH_SST) /* NOR protection support for STmicro/Micron chips and similar */ if (JEDEC_MFR(info) == SPI_FLASH_CFI_MFR_STMICRO || + JEDEC_MFR(info) == SPI_FLASH_CFI_MFR_MICRON || JEDEC_MFR(info) == SPI_FLASH_CFI_MFR_SST) { flash->flash_lock = stm_lock; flash->flash_unlock = stm_unlock; diff --git a/drivers/mtd/spi/spi_flash_ids.c b/drivers/mtd/spi/spi_flash_ids.c index edca94e..f144cc3 100644 --- a/drivers/mtd/spi/spi_flash_ids.c +++ b/drivers/mtd/spi/spi_flash_ids.c @@ -133,6 +133,7 @@ const struct spi_flash_info spi_flash_ids[] = { {"n25q1024a", INFO(0x20bb21, 0x0, 64 * 1024, 2048, RD_FULL | WR_QPP | E_FSR | SECT_4K) }, {"mt25qu02g", INFO(0x20bb22, 0x0, 64 * 1024, 4096, RD_FULL | WR_QPP | E_FSR | SECT_4K) }, {"mt25ql02g", INFO(0x20ba22, 0x0, 64 * 1024, 4096, RD_FULL | WR_QPP | E_FSR | SECT_4K) }, + {"mt35xu512g", INFO6(0x2c5b1a, 0x104100, 128 * 1024, 512, E_FSR | SECT_4K) }, #endif #ifdef CONFIG_SPI_FLASH_SST /* SST */ {"sst25vf040b", INFO(0xbf258d, 0x0, 64 * 1024, 8, SECT_4K | SST_WR) }, -- 1.9.1 _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de https://lists.denx.de/listinfo/u-boot
