| * tegra: nand: make ONFI detection workLucas Stach2012-10-29-0/+36
| | | | | | | | | | | | | | | | | | | | | | | | Add the missing bits to the Tegra NAND driver to make ONFI detection work properly. Also add it to the Tegra default config, as it seems to be a reasonable thing to have it available on all boards that use any kind of NAND.

* | include/linux/byteorder: import latest endian definitions from linuxKim Phillips2012-11-04-10/+2
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | u-boot's byteorder headers did not contain endianness attributions for use with sparse, causing a lot of false positives. Import the kernel's latest definitions, and enable them by including compiler.h and types.h. They come with 'const' added for some swab functions, so fix those up, too: include/linux/byteorder/big_endian.h:46:2: warning: passing argument 1 of '__swab64p' discards 'const' qualifier from pointer target type [enabled by default] Also, note: u-boot's historic __BYTE_ORDER definition has been preserved (for the time being at least). We also remove ad-hoc barrier() definitions, since we're including compiler.h in files that hadn't in the past: macb.c:54:0: warning: "barrier" redefined [enabled by default] In addition, including compiler.h in byteorder changes the 'noinline' definition to expand to __attribute__((noinline)).

| | | | | | | | | | | The move is pretty straight-forward. ap20.h and tegra20.h were renamed to ap.h and tegra.h. Some files remain in arch-tegra20 but 'include' a file in 'arch-tegra' with #defines & structs that will be common between T20 and T30 HW. HW-specific #defines, etc. stay in the 'arch-tegra20' 'root' file. All boards build OK w/MAKEALL -s tegra20. Checkpatch.pl runs clean. Seaboard works OK.

It silently masks off at least one flag that might be set by the driver (NAND_NO_SUBPAGE_WRITE). This breaks the GPMI NAND driver and possibly others. Really, as long as driver writers exercise a small amount of care with NAND_* options, this mask is not necessary at all; it was only here to prevent certain options from accidentally being set by the driver. But the original thought turns out to be a bad idea occasionally. Thus, kill it. Note, this patch fixes some major gpmi-nand breakage.

| | | | | | | | | | | | | | | | | | The Programmable Multibit ECC (PMECC) controller is a programmable binary BCH(Bose, Chaudhuri and Hocquenghem) encoder and decoder. This controller can be used to support both SLC and MLC NAND Flash devices. It supports to generate ECC to correct 2, 4, 8, 12 or 24 bits of error per sector of data. To use PMECC in this driver, the user needs to set the PMECC correction capability, the sector size and ROM lookup table offsets in board config file. This driver is ported from Linux kernel atmel_nand PMECC patch. The main difference is in this version it uses registers structure access hardware instead of using macros.

| * sf: stmicro: support JEDEC standard two-byte signatureStephan Linz2012-08-09-12/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | There are more than the M25Pxx serial flashs that can be used with the stmicro driver, for example: the M25PXxx or N25Qxx serie. All these chips have burned in the original stmicro manufacture id 0x20 together with a standard two-byte signature. In preperation to support all these chips the stmicro driver have to decode the full two-byte signature.

* | mtd/cfi_flash: fix write problems for Numonyx P33/30 32 MBit flashsHolger Brunck2012-08-13-22/+43
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 54652991 Work around bug in Numonyx P33/P30 256-Mbit 65nm flash chips fixes a problem for Numonyx P33/P30 flashes for 256-Mbit, but this leads to problems for smaller versions of this chip e.g. the 32Mbit version with deviceid 0x16 on mgcoge. So move the code for this work around to an own function and check previously manufacturer id and device id to not break other flashes which don't need this work around.

* | cfi_flash: add support for Spansion flash PPB sector protectionAnatolij Gustschin2012-08-13-0/+52
|/ | | | | | | | | | Erasing flash sectors protected with persistent protection bit (PPB) mechanism on Spansion flash chips doesn't work. Add sector protection status checking and sector lock and unlock commands to fix this.
