mtd, omap: fix case NAND_OMAP_GPMC_PREFETCH not defined

2015-02-16T17:41:40Z

The patch c316f577b4b72d1a1aeb559e9b3fad20808f1ffd breaks siemens boards because prefetch mode is not enabled. I assume it breaks other boards as well that don't use prefetch. This patch sets read_buf to nand_read_buf if NAND_OMAP_GPMC_PREFETCH is not defined. Signed-off-by: Samuel Egli CC: Daniel Mack CC: Guido Martínez CC: Tom Rini CC: Heiko Schocher

dm: Expand and complete Kconfig in drivers/

2015-02-12T17:35:33Z

mtd: atmel_nand: according to pmecc version to perform 0xff page correction

2015-02-07T22:42:57Z

As the PMECC hardware has different version. In SAMA5D4 chip, the PMECC ip can generate 0xff pmecc ECC value for all 0xff sector. According to this, add PMECC version check, if it's SAMA5D4 then we always let PMECC hardware to correct it. Signed-off-by: Josh Wu Acked-by: Bo Shen Acked-by: Andreas Bießmann

dm: spi: Move slave details to child platdata

2015-01-30T00:09:56Z

At present we go through various contortions to store the SPI slave's chip select in its private data. This only exists when the slave is active so must be set up when it is probed. Until the device is probed we don't actually know what chip select it will appear on. However, now that we can support per-child platform data, we can use that instead. This allows us to set up the chip select when the child is bound, and avoid the messy contortions. Unfortunately this is a fairly large change and it seems to be difficult to break it down further.

These functions are going away, so use the new uclass support instead. Signed-off-by: Simon Glass

ubi: reset mtd_devs when ubi part fail

2015-01-28T06:41:18Z

if "ubi part" fails, reset also mtd_devs to 0, as further "ubi part" would use wrong mtd_devs. Signed-off-by: Heiko Schocher

powerpc: ppc4xx: remove PPChameleonEVB, CATcenter boards

2015-01-23T21:53:36Z

These boards are still non-generic boards. It is a good thing that we can drop board-specific hack code from drivers/mtd/nand/nand_base.c Signed-off-by: Masahiro Yamada Acked-by: Stefan Roese Cc: Andrea "llandre" Marson

mtd: OMAP: Enable GPMC prefetch mode

2015-01-13T16:51:23Z

Enable GPMC's prefetch feature for NAND access. This speeds up NAND read access a lot by pre-fetching contents in the background and reading them through the FIFO address. The current implementation has two limitations: a) it only works in 8-bit mode b) it only supports read access Both is easily fixable by someone who has hardware to implement it. Note that U-Boot code uses non word-aligned buffers to read data into, and request read lengths that are not multiples of 4, so both partial buffers (head and tail) have to be addressed. Tested on AM335x hardware. Tested-by: Guido Martínez Reviewed-by: Guido Martínez Signed-off-by: Daniel Mack [trini: Make apply again, use 'cs' fix pointed out by Guido] Signed-off-by: Tom Rini
