2012-08-03	5a69305 Browse files » mtd OMAP NAND: Use prefetch engine ... Use the prefetch engine to improve NAND performance. The howto is derived from the Kernel. Unlike the kernel we do not make the access mode configurable. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Sascha Hauer committed on 3 Aug 2012
2012-08-02	ee5a0fc Browse files » mtd OMAP NAND: Fix dev_ready handling ... - dev_ready is supposed to return whether the device is ready or not, not to poll until the device is ready. - dev_ready should return true for ready and false for not ready - waitpin polarity is not needed (at least the kernel does not have it) - wait_mon_mask must be 32bit. The code was unused since no board specified a wait pin, so no breakage included. This also removes the now unused timeout variable from platformdata.

2012-01-16	d002818 Browse files » fix gpmc_nand_probe without param support ... commit `30de24d` param: add config to disable it removes param support for xloader configurations. Set param eccmode calls omap_gpmc_eccmode and so nand_scan_tail. So nand fails without param support Call omap_gpmc_eccmode directly if CONFIG_PARAMETER is not enabled to fix that.
