* ARM: OMAP2+: Prepare to move GPMC to drivers by platform data headerTony Lindgren2014-11-201-2/+1
| | | | | | | | | | | | | | | | | | We still need to support platform data for omap3 until it's booting in device tree only mode. So let's add platform_data/omap-gpmc.h for that, and a minimal linux/omap-gpmc.h for the save and restore used by the PM code. Let's also keep a minimal mach-omap2/gpmc.h still around to avoid churn on the board-*.c files. Once omap3 boots in device tree only mode, we can drop mach-omap2/gpmc.h and we can make the data structures in platform_data/omap-gpmc.h private to the GPMC driver. Note that we can now also remove gpmc-nand.h and gpmc-onenand.h. Cc: Arnd Bergmann <arnd@arndb.de> Acked-by: Roger Quadros <rogerq@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
* mtd: nand: omap: Revert to using software ECC by defaultRoger Quadros2014-08-261-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | For v3.12 and prior, 1-bit Hamming code ECC via software was the default choice. Commit c66d039197e4 in v3.13 changed the behaviour to use 1-bit Hamming code via Hardware using a different ECC layout i.e. (ROM code layout) than what is used by software ECC. This ECC layout change causes NAND filesystems created in v3.12 and prior to be unusable in v3.13 and later. So revert back to using software ECC by default if an ECC scheme is not explicitely specified. This defect can be observed on the following boards during legacy boot -omap3beagle -omap3touchbook -overo -am3517crane -devkit8000 -ldp -3430sdp Signed-off-by: Roger Quadros <rogerq@ti.com> Tested-by: Grazvydas Ignotas <notasas@gmail.com> Signed-off-by: Tony Lindgren <tony@atomide.com>

| * ARM: OMAP2+: raw read and write endian fixVictor Kamensky2014-05-081-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | All OMAP IP blocks expect LE data, but CPU may operate in BE mode. Need to use endian neutral functions to read/write h/w registers. I.e instead of __raw_read[lw] and __raw_write[lw] functions code need to use read[lw]_relaxed and write[lw]_relaxed functions. If the first simply reads/writes register, the second will byteswap it if host operates in BE mode. Changes are trivial sed like replacement of __raw_xxx functions with xxx_relaxed variant.

| | | | | | | | | | | | | | This patch removes omap2_nand_gpmc_retime() which was used to quirk some timing values before gpmc_cs_set_timings().

| | | | | | | | | | | | | | | | We want to remove plat/cpu.h. To do this, let's first split it to private soc.h to mach-omap1 and mach-omap2.

* ARM: OMAP: Split plat/hardware.h, use local soc.h for omap2+Tony Lindgren2012-09-131-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As the plat and mach includes need to disappear for single zImage work, we need to remove plat/hardware.h. Do this by splitting plat/hardware.h into omap1 and omap2+ specific files. The old plat/hardware.h already has omap1 only defines, so it gets moved to mach/hardware.h for omap1. For omap2+, we use the local soc.h that for now just includes the related SoC headers to keep this patch more readable. Note that the local soc.h still includes plat/cpu.h that can be dealt with in later patches. Let's also include plat/serial.h from common.h for all the board-*.c files. This allows making the include files local later on without patching these files again. Note that only minimal changes are done in this patch for the drivers/watchdog/omap_wdt.c driver to keep things compiling. Further patches are needed to eventually remove cpu_is_omap usage in the drivers. Also only minimal changes are done to sound/soc/omap/* to remove the unneeded includes and to define OMAP44XX_MCPDM_L3_BASE locally so there's no need to include omap44xx.h. While at it, also sort some of the includes in the standard way.

| | | | | | | | | | | | | | | | | | | | | | | As the interrupts should only be defined in the platform_data, and eventually coming from device tree, there's no need to define them in header files. Let's remove the hardcoded references to irqs.h and fix up the includes so we don't rely on headers included in irqs.h. Note that we're defining OMAP_INTC_START as 0 to the interrupts. This will be needed when we enable SPARSE_IRQ. For some drivers we need to add #include <plat/cpu.h> for now until these drivers are fixed to remove cpu_is_omapxxxx() usage. While at it, sort som of the includes the standard way, and add the trailing commas where they are missing in the related data structures.

This is both incorrect and confusing, so remove them. This allows to get rid of a global variable in gpmc-nand.c. This also corrects an issue where some boards are trying to pass NAND 16bit flag through .options, but the driver is using .devsize instead and ignoring .options. Finally, .dev_ready is treated as a flag by the driver, so make it bool instead of a function pointer.
