[U-Boot] [PATCH] am335x: NAND: add BCH16 and 4k page size support
by Jordy van Wolferen 29 Jan '13

29 Jan '13

This is tested with a custom AM3359 (rev 2.0) board. NAND chip: MT29F16G08ABABAWP This code allows me to boot from ROM code. The ROM code forces BCH16 on NAND chips with a 4k page size. BCH16 is not enabled by default. --- arch/arm/include/asm/arch-am33xx/cpu.h | 8 +- arch/arm/include/asm/arch-am33xx/omap_gpmc.h | 43 ++++++++ drivers/mtd/nand/omap_gpmc.c | 150 +++++++++++++++++---------- include/linux/mtd/mtd-abi.h | 2 +- 4 files changed, 148 insertions(+), 55 deletions(-) diff --git a/arch/arm/include/asm/arch-am33xx/cpu.h b/arch/arm/include/asm/arch-am33xx/cpu.h index 16e8a80..0a1f1ff 100644 --- a/arch/arm/include/asm/arch-am33xx/cpu.h +++ b/arch/arm/include/asm/arch-am33xx/cpu.h @@ -78,6 +78,10 @@ struct bch_res_0_3 { u32 bch_result_x[4]; }; +struct bch_res_4_6 { + u32 bch_result_x[3]; +}; + struct gpmc { u8 res1[0x10]; u32 sysconfig; /* 0x10 */ @@ -107,7 +111,9 @@ struct gpmc { u8 res7[12]; /* 0x224 */ u32 testmomde_ctrl; /* 0x230 */ u8 res8[12]; /* 0x234 */ - struct bch_res_0_3 bch_result_0_3[2]; /* 0x240 */ + struct bch_res_0_3 bch_result_0_3; /* 0x240 */ + u32 dummy[44]; /* not used */ + struct bch_res_4_6 bch_result_4_6; /* 300 */ }; /* Used for board specific gpmc initialization */ diff --git a/arch/arm/include/asm/arch-am33xx/omap_gpmc.h b/arch/arm/include/asm/arch-am33xx/omap_gpmc.h index 572f9d0..534fa6e 100644 --- a/arch/arm/include/asm/arch-am33xx/omap_gpmc.h +++ b/arch/arm/include/asm/arch-am33xx/omap_gpmc.h @@ -117,4 +117,47 @@ {.offset = 106,\ .length = 8 } } \ } + +#define GPMC_NAND_4K_HW_BCH8_ECC_LAYOUT {\ + .eccbytes = 112,\ + .eccpos = {2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15,\ + 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27,\ + 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39,\ + 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51,\ + 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63,\ + 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75,\ + 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87,\ + 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99,\ + 100, 101, 102, 103, 104, 105, 106, 107, 108, 109,\ + 110, 111, 112, 113},\ + .oobfree = {\ + {.offset = 114,\ + .length = 110 } } \ +} + +#define GPMC_NAND_4K_HW_BCH16_ECC_LAYOUT {\ + .eccbytes = 208,\ + .eccpos = { 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15,\ + 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27,\ + 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39,\ + 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51,\ + 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63,\ + 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75,\ + 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87,\ + 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99,\ + 100, 101, 102, 103, 104, 105, 106, 107, 108, 109,\ + 110, 111, 112, 113, 114, 115, 116, 117, 118, 119,\ + 120, 121, 122, 123, 124, 125, 126, 127, 128, 129,\ + 130, 131, 132, 133, 134, 135, 136, 137, 138, 139,\ + 140, 141, 142, 143, 144, 145, 146, 147, 148, 149,\ + 150, 151, 152, 153, 154, 155, 156, 157, 158, 159,\ + 160, 161, 162, 163, 164, 165, 166, 167, 168, 169,\ + 170, 171, 172, 173, 174, 175, 176, 177, 178, 179,\ + 180, 181, 182, 183, 184, 185, 186, 187, 188, 189,\ + 190, 191, 192, 193, 194, 195, 196, 197, 198, 199,\ + 200, 201, 202, 203, 204, 205, 206, 207, 208, 209},\ + .oobfree = {\ + {.offset = 210,\ + .length = 14 } } \ +} #endif /* __ASM_ARCH_OMAP_GPMC_H */ diff --git a/drivers/mtd/nand/omap_gpmc.c b/drivers/mtd/nand/omap_gpmc.c index cee394e..3c42a54 100644 --- a/drivers/mtd/nand/omap_gpmc.c +++ b/drivers/mtd/nand/omap_gpmc.c @@ -76,8 +76,8 @@ int omap_spl_dev_ready(struct mtd_info *mtd) /* * omap_hwecc_init - Initialize the Hardware ECC for NAND flash in - * GPMC controller - * @mtd: MTD device structure + * GPMC controller + * @mtd: MTD device structure * */ static void __maybe_unused omap_hwecc_init(struct nand_chip *chip) @@ -170,19 +170,19 @@ static int __maybe_unused omap_correct_data(struct mtd_info *mtd, uint8_t *dat, } /* - * omap_calculate_ecc - Generate non-inverted ECC bytes. + * omap_calculate_ecc - Generate non-inverted ECC bytes. * - * Using noninverted ECC can be considered ugly since writing a blank - * page ie. padding will clear the ECC bytes.

[U-Boot] Current state and existing users of FIT (Flattened Image Tree)?
by Joel A Fernandes 29 Jan '13

29 Jan '13

Just trying to correlate old patches on U-boot mailing list to draw a picture of the current state of FIT (Flattened Image Tree format).. still have the following questions: Can anyone familiar with this topic comment on the following? (1) Other than Chromium OS, who are the most notable examples/users of FIT? (2) There is no kernel build support for FIT (all patches that were sent for building FIT from kernel sources were NAK'ed). How does chromium-OS or other platforms build FIT images today? (3) Are there any open examples on the web or in the sources for any existing open source projects that show a working example of FIT? The only example I could find were few .its files in the U-boot doc/uImage.FIT directory. Thanks! Joel

[U-Boot] [PATCH v3 1/3] mxs: Rename CONFIG_SPL_MX28_PSWITCH_WAIT to CONFIG_SPL_MXS_PSWITCH_WAIT
by Otavio Salvador 29 Jan '13

29 Jan '13

The power switch option is compatible with i.MX23 and i.MX28 so the configration option needs to reflect it. We choose 'CONFIG_SPL_MXS_PSWITCH_WAIT' for the option name.
