[U-Boot] fpga - parallel flash
by Klemen Dovrtel 21 Mar '13

21 Mar '13

Hello everybody, I have got the Spartan 3E Smple Pack with Intel Parallel Flash. I would like to load the parallel flash with the design I synthesized with ISE. So i need some kind of loader for the parallel flash which will run on the fpga. Can this be done with U-Boot? Regards, Klemen

[U-Boot] [PATCH v2 1/2] omap_hsmmc: Check wp and cd GPIO for valid GPIO first
by Tom Rini 21 Mar '13

21 Mar '13

When we cannot check write protect or card change via GPIO (and have been passed -1 in omap_mmc_init), only even try the gpio_is_valid is true. This prevents invalid GPIO messages from being seen on the console when doing MMC operations Signed-off-by: Tom Rini <trini(a)ti.com> --- Changes in v2: - Use gpio_is_valid not just a check for >= 0 (Fabio Estevam) --- drivers/mmc/omap_hsmmc.c | 12 ++++++++++-- 1 file changed, 10 insertions(+), 2 deletions(-) diff --git a/drivers/mmc/omap_hsmmc.c b/drivers/mmc/omap_hsmmc.c index 67cfcc2..8a5dce5 100644 --- a/drivers/mmc/omap_hsmmc.c +++ b/drivers/mmc/omap_hsmmc.c @@ -73,13 +73,21 @@ static int omap_mmc_setup_gpio_in(int gpio, const char *label) static int omap_mmc_getcd(struct mmc *mmc) { int cd_gpio = ((struct omap_hsmmc_data *)mmc->priv)->cd_gpio; - return gpio_get_value(cd_gpio); + + if (gpio_is_valid(cd_gpio)) + return gpio_get_value(cd_gpio); + else + return -1; } static int omap_mmc_getwp(struct mmc *mmc) { int wp_gpio = ((struct omap_hsmmc_data *)mmc->priv)->wp_gpio; - return gpio_get_value(wp_gpio); + + if (gpio_is_valid(wp_gpio)) + return gpio_get_value(wp_gpio); + else + return -1; } #else static inline int omap_mmc_setup_gpio_in(int gpio, const char *label) -- 1.7.9.5

[U-Boot] Micron MT29F8G Internal 4 BIT ECC
by Plenty, Richard 21 Mar '13

21 Mar '13

Hi, I was wondering if anyone has had experience of enabling the internal 4 BIT ECC used on the Micron MT29F8G08ADADAH4-IT and the Freescale QorIQ. I'm particularly keen to see the modifications you may have done to the Special programme loader (nand_boot_fsl_elbc.c) so that the FCM error correction is replaced by the internal ECC of the Micron device once the initial stage 0 loader has completed.

[U-Boot] [PATCH 2/5] powerpc/mpc85xx: new SPL support for IFC NAND
by Prabhakar Kushwaha 21 Mar '13

21 Mar '13

Linker script is not able find start.o binary. So add its absolute path in u-boot-spl.lds. This change is similar to u-boot-nand.lds common/Makefile: Avoid compiling unnecssary files fsl_ifc_spl.c : It is is responsible for reading u-boot binary from NAND flash and copying into DDR. It also transfer cotrol from NAND SPL to u-boot image present in DDR.

[U-Boot] [PATCH 1/5] powerpc/mpc85xx:No NOR boot, do not compile IFC errata A003399

[U-Boot] new SPL support for IFC based Feescale platforms
by Prabhakar Kushwaha 21 Mar '13

21 Mar '13

This patch series ports existing Freescale's IFC based platforms/boards to new SPL based architecture. It is done to support NAND boot. It contains following patches: 1. powerpc/mpc85xx:No NOR boot,do not compile IFC errata A003399 2. powerpc/mpc85xx: new SPL support for IFC NAND 3. board/p1010rdb:Add NAND boot support using new SPL format 4. board/bsc9131rdb:Add NAND boot support using new SPL format 5. board/bsc9132qds:Add NAND boot support using new SPL format
