If we don't have OpenFirmware enabled then provide a stub of_mtd_parse_partitions that returns no partitions so drivers don't need ifdeffery inside. Signed-off-by:
-
Jamie Iles authored
To prepare for the removal of add_mtd_device and add_mtd_partitions(), introduce mtd_device_register(). This will create partitions if they are supplied or register the whole device if there are no partitions. Once all drivers are converted to use mtd_device_register(), add_mtd_device() and add_mtd_partitions() will be made internal only. v2: move kerneldoc to implementation file and fixup some kerneldoc warnings. Artem: tweak comments: remove junk tabs, use dots consistently. Signed-off-by:

There are very few situations where MTD partitioning is not required, and the benefit in code size reduction by making this configurable does not warrant the level of ifdeffery needed. Artem: this patch is not final - we just make sure that mtd partitions are always compiled in, and at the end of the series we'll kill MTD_PARTITIONS altogether. Signed-off-by:

This is a trivial patch which removes unnecessary assignment of chip->state in put_chip(). It's duplicated. Signed-off-by:

cfi erase command hangs up when erase and read contention occurs. If read runs at the same address as erase operation, read issues Erase-Suspend via get_chip() and the erase goes into sleep in wait queue. But in this case, read operation exits by time-out without waking it up. I think the other variants (0001, 0020 and lpddr) have the same problem too. Tested and verified the patch only on CFI-0002 flash, though. Signed-off-by:

'get_mtd_device_nm()' has a piece of code which equivalent to what '__get_mtd_device()' does - remove this duplicated code and use ''__get_mtd_device()' instead. Artem: changed commit message. Artem: while on it, remove an unnecessary extra empty line Signed-off-by:

Currently when we register partitions in 'parse_mtd_partitions()' we accept the list of parsers we should try. And if one of the parsers was not found we print a message. Well, first of all this whole idea is bad - look at how many 'part_probes' and 'part_probe_types' variables we have - nearly every driver defines one. Instead, we should just go through all registered parsers all the time. But this needs to be worked on separately. This patch makes life of MTD partitions' users a bit simpler and allows them to safely request parsers which have not been registered - 'parse_mtd_partitions()' will not print a "not available" message in this case. The point is that drivers do not have to do things like this any longer: static const char *part_probe_types[] = { "cmdlinepart", "RedBoot", "afs", NULL }; but can simply do like this: static const char *part_probe_types[] = { "cmdlinepart", "RedBoot", "afs", NULL }; Signed-off-by: -

When reading/writing a subpage (When HW ECC is not available/enabled) for number of bytes not aligned to 4, the mis-aligned bytes are handled first (by cpu copy method) before enabling the Prefetch engine to/from 'p'(start of buffer 'buf'). Then it reads/writes rest of the bytes with the help of Prefetch engine, if available, or again using cpu copy method. Currently, reading/writing of rest of bytes, is not done correctly since its trying to read/write again to/from begining of buffer 'buf', overwriting the mis-aligned bytes. Read & write using prefetch engine got broken in commit '2c01946c'. We never hit a scenario of not getting 'gpmc_prefetch_enable' call success. So, problem did not get caught up. Signed-off-by:

The previous section mismatch fix for this driver wasn't entirely correct. The sst25l_flash_info array is now used in the devinit probe func, but is marked as initdata, so building results in the warning: WARNING: drivers/mtd/devices/sst25l.o(.devinit.text): Section mismatch in reference from the function sst25l_probe() to the variable .init.data:sst25l_flash_info Further, the remove func should be devexit rather than exit to match the probe func.

S25FL512S = 64MiB single die, same family as S25FL256S S70FL01GS = 2x S25FL512S dies in one package (separate chip selects) These devices are not sampling yet, but they are expected to be very similar to S25FL256S, which has been tested. Signed-off-by:

Not all configurations of the Denali controller support 4 banks. The controller can support between 1 and 16 banks. Detect this from the design features register. Signed-off-by:

Jamie Iles authored
The controller has interrupt enable/status register pairs for each bank (along with ECC and status registers) that differ only in address offset. Rather than providing definitions for each register, make the address a macro so that it scales for devices with different numbers of banks. Signed-off-by:

Rather than using the PCI specific DMA API, convert to the generic DMA API so that we can use the Denali NAND controller on other bus types. Signed-off-by:
