new chips supported:- MX25L1605D, MX25L3205D, MX25L6405D, MX25L12855E out of which MX25L6405D and MX25L12855E tested on Kirkwood platforms
Modified the Macronix flash support to use 2 bytes of device id instead of 1 This was required to support MX25L12855E Contributor: Piyush Shah <[email protected]> Signed-off-by: Prafulla Wadaskar <[email protected]> --- drivers/mtd/spi/macronix.c | 63 ++++++++++++++++++++++++++++++++++++------- 1 files changed, 52 insertions(+), 11 deletions(-) diff --git a/drivers/mtd/spi/macronix.c b/drivers/mtd/spi/macronix.c index 9464c84..e6f87fb 100644 --- a/drivers/mtd/spi/macronix.c +++ b/drivers/mtd/spi/macronix.c @@ -49,17 +49,21 @@ #define CMD_MX25XX_DP 0xb9 /* Deep Power-down */ #define CMD_MX25XX_RES 0xab /* Release from DP, and Read Signature */ -#define MXIC_ID_MX2516 0x15 -#define MXIC_ID_MX2520 0x12 -#define MXIC_ID_MX2532 0x16 -#define MXIC_ID_MX2540 0x13 -#define MXIC_ID_MX2564 0x17 -#define MXIC_ID_MX2580 0x14 -#define MXIC_ID_MX25128 0x18 - +#define MXIC_ID_MD_MX251605D 0x15 /* MD : Memory Density */ +#define MXIC_ID_MT_MX251605D 0x20 /* MT : Memory Type */ +#define MXIC_ID_MD_MX253205D 0x16 /* MD : Memory Density */ +#define MXIC_ID_MT_MX253205D 0x20 /* MT : Memory Type */ +#define MXIC_ID_MD_MX256405D 0x17 /* MD : Memory Density */ +#define MXIC_ID_MT_MX256405D 0x20 /* MT : Memory Type */ +#define MXIC_ID_MD_MX2512805D 0x18 /* MD : Memory Density */ +#define MXIC_ID_MT_MX2512805D 0x20 /* MT : Memory Type */ +#define MXIC_ID_MD_MX2512855E 0x18 /* MD : Memory Density */ +#define MXIC_ID_MT_MX2512855E 0x26 /* MT : Memory Type */ + #define MACRONIX_SR_WIP (1 << 0) /* Write-in-Progress */ struct macronix_spi_flash_params { + u8 idcode0; u8 idcode1; u16 page_size; u16 pages_per_sector; @@ -81,13 +85,50 @@ static inline struct macronix_spi_flash *to_macronix_spi_flash(struct spi_flash static const struct macronix_spi_flash_params macronix_spi_flash_table[] = { { - .idcode1 = MXIC_ID_MX25128, + .idcode0 = MXIC_ID_MT_MX251605D, + .idcode1 = MXIC_ID_MD_MX251605D, + .page_size = 256, + .pages_per_sector = 16, + .sectors_per_block = 16, + .nr_blocks = 32, + .name = "MX25L1605D", + }, + { + .idcode0 = MXIC_ID_MT_MX253205D, + .idcode1 = MXIC_ID_MD_MX253205D, + .page_size = 256, + .pages_per_sector = 16, + .sectors_per_block = 16, + .nr_blocks = 64, + .name = "MX25L3205D", + }, + { + .idcode0 = MXIC_ID_MT_MX256405D, + .idcode1 = MXIC_ID_MD_MX256405D, + .page_size = 256, + .pages_per_sector = 16, + .sectors_per_block = 16, + .nr_blocks = 128, + .name = "MX25L6405D", + }, + { + .idcode0 = MXIC_ID_MT_MX2512805, + .idcode1 = MXIC_ID_MD_MX2512805, .page_size = 256, .pages_per_sector = 16, .sectors_per_block = 16, .nr_blocks = 256, .name = "MX25L12805D", }, + { + .idcode0 = MXIC_ID_MT_MX2512855E, + .idcode1 = MXIC_ID_MD_MX2512855E, + .page_size = 256, + .pages_per_sector = 16, + .sectors_per_block = 16, + .nr_blocks = 256, + .name = "MX25L12855E", + }, }; static int macronix_wait_ready(struct spi_flash *flash, unsigned long timeout) @@ -280,12 +321,12 @@ struct spi_flash *spi_flash_probe_macronix(struct spi_slave *spi, u8 *idcode) for (i = 0; i < ARRAY_SIZE(macronix_spi_flash_table); i++) { params = ¯onix_spi_flash_table[i]; - if (params->idcode1 == idcode[2]) + if (params->idcode1 == idcode[2] && params->idcode0 == idcode[1]) break; } if (i == ARRAY_SIZE(macronix_spi_flash_table)) { - debug("SF: Unsupported Macronix ID %02x\n", idcode[1]); + debug("SF: Unsupported Macronix ID %02x%02x\n", idcode[1],idcode[2]); return NULL; } -- 1.5.3.3 _______________________________________________ U-Boot mailing list [email protected] http://lists.denx.de/mailman/listinfo/u-boot
