2GB xD card, and 4MB SmartMedia ROM card share same ID, so to make both work split xD and smartmedia ID tables. Hardware driver must be able to know which type it handles (and probably just one).

On i.MX21 SoCs, if the NFC_CONFIG1:NFC_INT_MASK bit is set, NFC_CONFIG2:NFC_INT always reads out zero, even if an operation is completed. This patch uses enable_irq and disable_irq_nosync instead of NFC_CONFIG1:NFC_INT_MASK to mask NFC interrupts. This allows NFC_CONFIG2:NFC_INT to also be used to detect operation completion on i.MX21. The i.MX21 NFC does not signal reset completion using NFC_CONFIG1:NFC_INT_MASK, so instead reset completion is tested by checking if NFC_CONFIG2 becomes 0.

This patch allows the mxc_nand driver to reset the NAND flash controller. NFC registers are (re-)set after completion of the reset, as a reset will have reverted the NFC registers to their default values.

This is to support custom partitioning schemes for embedded PPC. To use define your own mtd_part_parser and then add something like: linux,part-probe = "my_probe", "cmdlinepart"; To the board's dts file. If linux,part-probe is not specified then this behaves the same as before. Signed-off-by: Jason Gunthorpe <jgunthorpe@obsidianresearch.com> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>

Stefani Seibold authored
The use of a memcpy() during a spinlock operation will cause very long thread context switch delays if the flash chip bandwidth is low and the data to be copied large, because a spinlock will disable preemption. For example: A flash with 6,5 MB/s bandwidth will cause under ubifs, which request sometimes 128 KiB (the flash erase size), a preemption delay of 20 milliseconds. High priority threads will not be served during this time, regardless whether this threads access the flash or not. This behavior breaks real time. The patch changes all the use of spin_lock operations for xxxx->mutex into mutex operations, which is exact what the name says and means. I have checked the code of the drivers and there is no use of atomic pathes like interrupt or timers. The mtdoops facility will also not be used by this drivers. So it is dave to replace the spin_lock against mutex. There is no performance regression since the mutex is normally not acquired.

Functions omap2_onenand_write_bufferram() and omap3_onenand_write_bufferram() map the write buffer and store the returned handle in variable dma_src. However, when DMA unmap is done, variable dma_dst is used instead of the correct dma_src. This patch fixes them to use the correct DMA buffer.

commit 672917dc ("cpuidle: menu governor: reduce latency on exit") added an optimization, where the analysis on the past idle period moved from the end of idle, to the beginning of the new idle. Unfortunately, this optimization had a bug where it zeroed one key variable for new use, that is needed for the analysis. The fix is simple, zero the variable after doing the work from the previous idle. During the audit of the code that found this issue, another issue was also found; the ->measured_us data structure member is never set, a local variable is always used instead.

Some time ago we stopped the clean/active metadata updates from being written to a 'spare' device in most cases so that it could spin down and say spun down. Device failure/removal etc are still recorded on spares. However commit 51d5668c broke this 50% of the time, depending on whether the event count is even or odd. The change log entry said: This means that the alignment between 'odd/even' and 'clean/dirty' might take a little longer to attain, how ever the code makes no attempt to create that alignment, so it could take arbitrarily long. So when we find that clean/dirty is not aligned with odd/even, force a second metadata-update immediately. There are already cases where a second metadata-update is needed immediately (e.g. when a device fails during the metadata update). We just piggy-back on that.
