* mtd: nand_plat: add simple GPIO framework DEV_READY optionMike Frysinger2010-07-08-0/+11

* sf: move useful messages from debug to printfMike Frysinger2010-06-30-16/+22
| | | | | | | | | | At the moment, the default SPI flash subsystem is quite terse. Errors and successes both result in a generic message. So move the useful errors and useful successes to printf output by default. While we're here, also convert the messages to use print_size(). Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* spi_flash: support old STMicro parts with RESThomas Chou2010-06-30-0/+22

* UBI: initialise update markerPeter Horton2010-06-23-0/+1
| | | | | | | | | | | | | | UBI: initialise update marker The in kernel copy of a volume's update marker is not initialised from the volume table. This means that volumes where an update was unfinnished will not be treated as "forbidden to use". This is basically that the update functionality was broken.

* Blackfin: nand: drain the write buffer before returningAndrew Caldwell2010-05-26-1/+6
| | | | | | | | | | | | | The current Blackfin nand write function fills up the write buffer but returns before it has had a chance to drain. On faster systems, this isn't a problem as the operation finishes before the ECC registers are read, but on slower systems the ECC may be incomplete when the core tries to read it. So wait for the buffer to drain once we're done writing to it. Signed-off-by: Andrew Caldwell <Andrew.Caldwell@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* UBI: Ensure that "background thread" operations are really executedStefan Roese2010-05-19-2/+7
| | | | | | | | | | | | The current U-Boot UBI implementation is copied from Linux. In this porting the UBI background thread was not handled correctly. Upon write operations ubi_wl_flush() makes sure, that all queued operations, like page-erase, are completed. But this is missing for read operations. This patch now makes sure that such operations (like scrubbing upon bit-flip errors) are not queued, but executed directly. Signed-off-by: Stefan Roese <sr@denx.de>

* cfi_flash: reset timer in flash status checkThomas Chou2010-04-07-0/+2
| | | | | | | | | | | | | | | | | This patch adds reset_timer() before the flash status check waiting loop. Since the timer is basically running asynchronous to the cfi code, it is possible to call get_timer(0), then only a few _SYSCLK_ cycles later an interrupt is generated. This causes timeout even though much less time has elapsed. So the timer period registers should be reset before get_timer(0) is called. There is similar usage in nand_base.c.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds status polling method to offer an alternative to data toggle method for amd flash chips. This patch is needed for nios2 cfi flash interface, where the bus controller performs 4 bytes read cycles for a single byte read instruction. The data toggle method can not detect chip busy status correctly. So we have to poll DQ7, which will be inverted when the chip is busy.

| * | | NAND: fix "raw" reads with ECC syndrome layoutsDavid Brownell2009-11-13-4/+96

With ECC chunk size of 512 bytes and a large page (2KiB) NAND, the layout is: data-0 OOB-0 data-1 OOB-1 data-2 OOB-2 data-3 OOB-3 OOB-leftover Where OOBx is (prepad, ECC, postpad). However, the current "raw" routines use a traditional layout -- data OOB, disregarding the prepad and postpad values -- so when they're used with that type of ECC hardware, those calls mix up the data and OOB. Which means, in particular, that bad block tables won't be found on startup, with data corruption and related chaos ensuing. The current syndrome-based drivers in mainline all seem to use one chunk per page; presumably they haven't noticed such bugs. Fix this, by adding read/write page_raw_syndrome() routines as siblings of the existing non-raw routines; "raw" just means to bypass the ECC computations, not change data and OOB layout.
