[U-Boot] [PATCH V2] OMAP3_logic: Add NAND args to boot UBIFS
by Adam Ford 15 Feb '16

15 Feb '16

With the recent addition of UBI support, this patch will add the preset parameters to allow for mouting an UBIFS from the 'fs' partition in NAND. -V2: ubi.mtd=fs instead of ubi.mtd=4 Signed-off-by: Adam Ford <aford173(a)gmail.com> --- include/configs/omap3_logic.h | 6 ++++++ 1 file changed, 6 insertions(+) diff --git a/include/configs/omap3_logic.h b/include/configs/omap3_logic.h index 9ea6ef3..fba2a12 100644 --- a/include/configs/omap3_logic.h +++ b/include/configs/omap3_logic.h @@ -180,6 +180,8 @@ "mmcdev=0\0" \ "mmcroot=/dev/mmcblk0p2 rw\0" \ "mmcrootfstype=ext4 rootwait\0" \ + "nandroot=ubi0:rootfs rw ubi.mtd=fs noinitrd\0" \ + "nandrootfstype=ubifs rootwait\0" \ "autoboot=mmc dev ${mmcdev}; if mmc rescan; then " \ "if run loadbootscript; then " \ "run bootscript; " \ @@ -221,6 +223,10 @@ "${optargs} " \ "root=${mmcroot} " \ "rootfstype=${mmcrootfstype}\0" \ + "nandargs=run setconsole; setenv bootargs console=${console} " \ + "${optargs} " \ + "root=${nandroot} " \ + "rootfstype=${nandrootfstype}\0" \ "fdtaddr=0x86000000\0" \ "loadfdtimage=mmc rescan; " \ "fatload mmc ${mmcdev} ${fdtaddr} ${fdtimage}\0" \ -- 1.9.1

[U-Boot] [PATCH] am43xx: qspi: Fix config to select SPI mode
by Vignesh R 15 Feb '16

15 Feb '16

CONFIG_SF_DEFAULT_MODE is used to select default SPI mode when using sf commands. Therefore fix am43xx to use CONFIG_SF_DEFAULT_MODE instead of CONFIG_DEFAULT_SPI_MODE.

[U-Boot] [PATCH] ARM : DRA7: Switch QSPI to use MODE-0 at 64MHz
by Vignesh R 15 Feb '16

15 Feb '16

According to Data Manual(SPRS915P) of AM572x, TI QSPI controller on DRA74 EVM(rev 1.1+) can support up to 64MHz in MODE-0, whereas MODE-3 is limited to 48MHz. Hence, switch to MODE-0 for better throughput. Also, add IODelay parameters for the same.

In 0ffe6ab we changed the test for status from the whole word to just starting with 's' which of course broke 'set', so change the test to 'st' so that it won't catch set (which is still just a test for 's').
