o Add a flag MTD_BIT_WRITEABLE for devices that allow single bits to be cleared. o Replace MTD_PROGRAM_REGIONS with a cleared MTD_BIT_WRITEABLE flag for STMicro and Intel Sibley flashes with internal ECC. Those flashes disallow clearing of single bits, unlike regular NOR flashes, so the new flag models their behaviour better. o Remove MTD_ECC. After the STMicro/Sibley merge, this flag is only set and never checked. Signed-off-by: NJoern Engel <joern@wh.fh-wedel.de>

In 2002, STMicro started producing NOR flashes with internal ECC protection for small blocks (8 or 16 bytes). Support for those flashes was added by me. In 2005, Intel Sibley flashes copied this strategy and Nico added support for those. Merge the code for both. Signed-off-by: NJoern Engel <joern@wh.fh-wedel.de>

At least two flashes exists that have the concept of a minimum write unit, similar to NAND pages, but no other NAND characteristics. Therefore, rename the minimum write unit to "writesize" for all flashes, including NAND. Signed-off-by: NJoern Engel <joern@wh.fh-wedel.de>

This is a 32MiB 8bit Toshiba device, with the data bus connected to the OMAP MPUIO pins and ALE, CLE, NCE, NRE, NWE and NWP all connected to the Delta's latch2 16bit latch.

There is a second revision of "mtdconcat NAND/Sibley" patch. I hope the patch will not get damaged as I'm posting it from gmail account, thanks to Jorn. The patch adds previously missing concat_writev(), concat_writev_ecc(), concat_block_isbad(), concat_block_markbad() functions to make concatenation layer compatible with Sibley and NAND chips. Patch has been cleared from whitespaces, fixed some lines of code as requested. Also I have added code for alignment check that should support Jorn's "writesize" patch.

This allows for much better abstraction and separation of the XIP and non-XIP cases with their own specific implementations. This fixes the case where a timeout was tripped on in the XIP case by the code that was meant for the non-XIP case only. This also makes for a nice code reduction.

On AMD Au1550 the static bus controller fails to keep -CE asserted during chip ready delay on read commands and the NAND chip being used requires this. So, the current driver allows nand_base.c to drive -CE manually during the entire sector read. When the PCMCIA driver is enabled however, occasionally the ECC errors occur on NAND reads. This happens because the PCMCIA driver polls sockets periodically and reads one of the board's control/status regs (BCSRs) which are on the same static bus as the NAND flash, and just use another chip select (and the NOR flash also resides on that bus), so as the NAND driver forces NAND chip select asserted and the -RE signal is shared, a contention occurs on the static bus when BCSR or NOR flash is read while we're reading from NAND. So, we either can't keep interrupts enabled during the whole NAND sector read (which is hardly acceptable), or have to implement some interlocking scheme between multiple drivers (which is painful, and makes me shudder :-). There's a third way which has proven to work: to force -CE asserted only while we're waiting for a NAND chip to become ready after a read command, disabling interrupts for a maximum of 25 microseconds (according to Toshiba TC58DVM92A1FT00 datasheet -- this chip is mentioned in the board schematics); for Samsung NAND chip which seems to be actually used this delay is even less, 12 us.

During the last cleanup of the AMD Au1550 NAND driver the old buglet was reintroduced: as the MEM_STNDCTL register is write-only and seem to always read as 0x31, read-modify-write to it done in au1xxx_nand_init() will have the side effect of enabling -RCS0/1 pin override (via bits 4/5 of this reg.), thus possibly causing a contention on the static bus when the NOR flash (using -RCS0) or board control status registers (using -RCS2) are read. Luckily, this goes away with a first NAND access, since au1550_hwcontrol() doesn't try to read this register before writing anymore.
