| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | By replacing a kthread with a workqueue, the code is now a bit clearer. There's also a slight reduction of code size (numbers apply for x86): Before: text data bss dec hex filename 3248 36 0 3284 cd4 drivers/mtd/mtd_blkdevs.o After: text data bss dec hex filename 3150 36 0 3186 c72 drivers/mtd/mtd_blkdevs.o Due to lack of real hardware, tests have been performed on an emulated environment with mtdswap and mtdblock over nandsim devices. Some real testing should be done, before merging this patch. Signed-off-by: Ezequiel Garcia <elezegarcia@gmail.com> Signed-off-by: Artem Bityutskiy <artem.bityutskiy@linux.intel.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we scan several nand chips with nand_scan(), such as ....................... nand_scan(*, 2); ....................... In nand_scan_ident(), the maxchips will become 2, so the current code will select chip 1 to read the device ID. But the chip 0 is still selected in this case. To make the logic clear, we'd better de-select the chip when it is not used. This patch de-select the nand chip if it is not used any more.

| * | mtd: nand_wait: warn if the nand is busy on exitMatthieu CASTET2012-11-151-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch allow to detect buggy driver/hardware with bad RnB (dev_ready) management or when timeout occurs in polling mode. This works when dev_ready is set or not set. There are 2 methods to wait for an erase/program command completion: 1. Wait until nand RnB pin goes high (that's what chip->dev_ready usually does) 2. Poll the device: send a status (0x70) command and read status byte in a loop until bit NAND_STATUS_READY is set In all cases, you should send a status command after completion, to check if the operation was successful. And if the operation completed, the status should have bit NAND_STATUS_READY set.

"mtd: partition size too small (0)" ............................................. We can not get any partition. The "4g(test)" partition triggers a overflow of the "size". The memparse() returns 4g to the "size", but the size is "unsigned long" type, so a overflow occurs, the "size" becomes zero in the end.

| * | mtdoops: don't erase flash at each bootMatthieu CASTET2012-11-151-8/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current version on mtdoops erase first block of mtdoops partition at each boot if there is no oops stored in flash. This can wear the flash. When mtdoops start, find_next_position is called to find the next free entry in the circular buffer. But if the flash is erased, find_next_position don't find anything (maxcount == 0xffffffff) and start with the first entry after erasing it. The scanning that is done in find_next_position already track free/used entries. So if at the end of the scanning we don't find anything, we can start at the first entry and erased the entry only if it is marked as used. Most of this is implemented in mtdoops_inc_counter, so to avoid duplicating code, if we don't find anything we set position to -1. mtdoops_inc_counter with increment it, erase the entry if needed and start as before with nextpage = 0 and nextcount = 1). Also during the scan phase, we use the MTDOOPS_KERNMSG_MAGIC to detect corruped entries.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Simply 'parse_cmdline_partitions': the outer loop iterating over 'partitions' is actually a search loop, it does not execute the inner loop for each partition, only for the matched partition. Let's break when search is successful, and move all inner code (relevant only for the matched partition) outside of the outer loop. Resulting code is much more readable, and makes the indent level sane. Signed-off-by: Shmulik Ladkani <shmulik.ladkani@gmail.com> Signed-off-by: Artem Bityutskiy <artem.bityutskiy@linux.intel.com>

The bulk of it is for OMAP/AM33xx platforms, but also a few around hotplug/suspend/resume on Exynos. It includes a split-up of some of the OMAP clock data into separate files which adds to the diffstat, but gross delta is fairly reasonable." * tag 'pm-merge' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (60 commits) ARM: OMAP: Move plat-omap/dma-omap.h to include/linux/omap-dma.h ASoC: OMAP: mcbsp fixes for enabling ARM multiplatform support watchdog: OMAP: fixup for ARM multiplatform support ARM: EXYNOS: Add flush_cache_all in suspend finisher ARM: EXYNOS: Remove scu_enable from cpuidle ARM: EXYNOS: Fix soft reboot hang after suspend/resume ARM: EXYNOS: Add support for rtc wakeup ARM: EXYNOS: fix the hotplug for Cortex-A15 ARM: OMAP2+: omap_device: Correct resource handling for DT boot ARM: OMAP2+: hwmod: Add possibility to count hwmod resources based on type ARM: OMAP2+: hwmod: Add support for per hwmod/module context lost count ARM: OMAP2+: PRM: initialize some PRM functions early ARM: OMAP2+: voltage: fixup oscillator handling when CONFIG_PM=n ARM: OMAP4: USB: power down MUSB PHY during boot ARM: OMAP2+: clock: Cleanup !CONFIG_COMMON_CLK parts ARM: OMAP2xxx: clock: drop obsolete clock data ARM: OMAP2: clock: Cleanup !CONFIG_COMMON_CLK parts ARM: OMAP3+: DPLL: drop !CONFIG_COMMON_CLK sections ARM: AM33xx: clock: drop obsolete clock data ARM: OMAP3xxx: clk: drop obsolete clock data ...
