| * | | | mtd: onenand: add workaround for SYNC_WRITE modeKyungmin Park2010-05-141-3/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some chips fails to identify properly when SYNC_WRITE mode is enabled (the example is OneNAND on S5PC110 SoC). This patch adds a workaround for such chips.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a new callback for the underlying drivers, which is called instead of accessing the buffer ram directly.

This approach leaves place to add a call to a fixup function to try to handle chips compatible with the early AMD specification from 1995 [2].

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.

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.

This causes __request_resource to return a conflict which then returns an -EBUSY error code. The current physmap.c code just assumes that the platfom_device_register will always succeed. Catch this failure during the physmap_init and propogate the error.

To permit for_each_clear_bit(), should that ever be added. I'll be sending a patch to Linus this week which removes the temporary for_each_bit() macro, so this patch will be needed to avoid build breakage.
