The following set of patches applies on top of for-next branch. http://git.kernel.org/?p=linux/kernel/git/tmlind/linux-omap-2.6.git Patches verified on: omap3430-SDP, omap3630-sdp, zoom3 and beagle board And these are the patches required to address the following input - 1. The NAND driver needs to stop tinkering with the GPMC registers The omap General Purpose Memory Controller (GPMC) registers are omap specific, and not driver specific. Tinkering with these registers can cause issues with the other devices on the GPMC. 2. Passing hardcoded GPMC_CS0_BASE needs to go from the board files Passing hardcoded GPMC virtual addressess is sure way to mess up things. This should all become unnecessary once the NAND drivers stops messing with the GPMC registers directly. Discussion: http://www.mail-archive.com/linux-omap@xxxxxxxxxxxxxxx/msg27630.html Changes in this series - gpmc_hwcontrol() function in gpmc.c, break into various small function. Unused function removed. v5: http://www.mail-archive.com/linux-omap@xxxxxxxxxxxxxxx/msg30305.html Functions related to ecc and prefetch engine are optimized. v4: http://www.mail-archive.com/linux-omap@xxxxxxxxxxxxxxx/msg29458.html Few functionality was missing like - There should be some locking as only one chipselect can use the ECC or prefetch engine at a time. If you have NAND in two chipselects, bad things would happen. v3: http://www.mail-archive.com/linux-omap@xxxxxxxxxxxxxxx/msg28715.html Additionally, it was needed to implement more functions for the platform init code to use. v2: http://www.mail-archive.com/linux-omap@xxxxxxxxxxxxxxx/msg28467.html v1: http://www.mail-archive.com/linux-omap@xxxxxxxxxxxxxxx/msg28164.html Sukumar Ghorai (3): omap3 gpmc: functionality enhancement omap3 nand: cleanup virtual address usages omap3 nand: fix issue in board file to detect nand arch/arm/mach-omap2/board-cm-t35.c | 20 +-- arch/arm/mach-omap2/board-devkit8000.c | 25 +--- arch/arm/mach-omap2/board-omap3beagle.c | 24 +--- arch/arm/mach-omap2/board-omap3touchbook.c | 25 +--- arch/arm/mach-omap2/board-overo.c | 24 +--- arch/arm/mach-omap2/board-sdp-flash.c | 5 - arch/arm/mach-omap2/gpmc-nand.c | 38 +--- arch/arm/mach-omap2/gpmc.c | 285 ++++++++++++++++++++++++++-- arch/arm/plat-omap/include/plat/gpmc.h | 42 ++++- arch/arm/plat-omap/include/plat/nand.h | 6 +- drivers/mtd/nand/omap2.c | 218 ++++++---------------- 11 files changed, 371 insertions(+), 341 deletions(-) -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
