2010-05-20nand : Add Freescale iMX27 nand flash controller supportgcembed
This patch add support of iMX27 nand flash controller. This is based on driver for imx31 nand flash controller. OOB functionality is not fully working. As in mx31 controller, mx2 NFC has a bug that swap two bytes between SPARE and MAIN buffer. I used this driver for several months and no problems appear.
2010-05-18NAND/davinci: Fix segfault for hwecc4_infix readsJon Povey
Page reads using hwecc4_infix layout segfaulted for check_bad_blocks because the read assumed a valid data buffer, which check_bad_blocks does not use (it only passes a 6 byte buffer for the start of OOB). This version copes with undersized or missing data or oob buffers and uses random read commands within the page to skip unwanted areas of data/OOB for speed. NOTE: Running check_bad_blocks with this layout will be reading infix OOB locations, not manufacturer bad block markers. This means that if you check blocks written in infix layout they will appear good, but manufacturer- marked bad blocks may also appear good. If you want to scan for manufactuer-marked bad blocks, you need to enable raw_access before running check_bad_blocks, or use the non-infix layout.

2010-05-18NAND: catch read errors when building BBTJon Povey
nand_build_bbt() was ignoring the return value from nand_read_page() and blindly continuing. It now passes the return value up to the caller if the read fails. Signed-off-by: Jon Povey <jon.povey@racelogic.co.uk>
2010-05-16Change kb/s to KiB/s in messages about kibibytesJon Povey
Change download rate messages about kibibytes from "kb/s" to "KiB/s" units. See: http://en.wikipedia.org/wiki/Data_rate_units Signed-off-by: Jon Povey <jon.povey@racelogic.co.uk>
2010-05-14NAND: fix first and last handling in nand_build_bbtJon Povey
Last block was being skipped, fix by changing the loop test from "<" to "<=" First block argument was ignored, always started from block 0 (and counted the wrong blocks as bad if first was nonzero). Now we use it. Signed-off-by: Jon Povey <jon.povey@racelogic.co.uk> Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>
2010-05-14NAND: fix off-by-one error in erase command argument rangeJon Povey
The last_block argument to nand_erase() is checked against nand->num_blocks, but the highest valid block number is (total - 1), the test for invalid should be ">=" rather than ">". Signed-off-by: Jon Povey <jon.povey@racelogic.co.uk> Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>

2010-03-16lpc3180: LPC3180(LPC3250) SLC driver implementedrichard vegh
Until this time only basic SLC functionality exists when you want to use SLC to access external nand flash. Basic functionality can be selected with command: lpc3180 select 0 slc It is anyway very slow to write/read to/from nand flash. With the new command, SLC speed improved about 20 times, and hardware ECC info also read/written from/to nand flash OOB area: lpc3180 select 0 slc bulk Speed improvement achieved by using working are in SRAM of the LPC3250 chip and controlling DMA controller to interact between SRAM and SLC peripheral. Here are the patches, and if they are ok than take them. Tested with hitex LPC3250 usb stick. Signed-off-by: Øyvind Harboe <oyvind.harboe@zylin.com>
2010-01-16NAND: lpc3180 crashes on LPC3250richard vegh
The LPC3180 NAND driver was crashing on some large page chips. Fix: - Crash and related functionality (don't memset too much OOB data) - Some debug messages - Command handling now works [dbrownell@users.sourceforge.net: whitespace/linelength/message cleanup] Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
2010-01-14nand flash support for s3c64xxPeter Korsgaard
Identical to the existing 2412/2443 support except for the base address and NFCONF value (bit 2 is reserved and should be written as 1 ref UM). Tested on a s3c6410 board, but controller is identical in 6400/6410 except for 8bit MLC ECC support in 6410 which isn't supported by the driver.

2010-01-08NAND: help/usage/doc updatesDavid Brownell
Usage messages should use the same EBNF as the User's Guide; no angle brackets. Be more complete too ... some params were missing. Improve and correct various helptexts. Make user's guide refer to the NAND "driver" name, not the controller name; that's a bit more precise. Don't use "&function"; its name is its address. Line up struct initializers properly. Remove some blank lines. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>

2009-12-19AT91SAM9 NAND flash driver.Dean Glazeski
This creates the TCL interface for configuring an AT91SAM9 NAND flash controller and implements the necessary functions to correctly work with a NAND flash device connected to the chip. This includes updates to the driver list and the Makefile.am to support building the driver and also houses the documentation update in openocd.texi.

2009-12-18NAND write data page refactoring.Dean Glazeski
Refactored the write page raw function into two new functions for writing data to a NAND device and then another function to finish up a write to a NAND device. This includes some new updates to introduce more error checking to existing code.

2009-12-18NAND read data page refactor.Dean Glazeski
Added a new function to encapsulate reading a page of data from a NAND device using either the read_block_data function of a NAND controller or to use direct reading of data from the NAND device. This also adds some performance enhancements and uses the read_data function if the read_block_data function fails safely (because it can't allocate a buffer in the working area).

2009-12-07ARM: use <target/arm.h> not armv4_5.hDavid Brownell
Move most declarations in <target/armv4_5.h> to <target/arm.h> and update users. What's left in the older file is stuff that I think should be removed ... the old register cache access stuff, which makes it awkward to support microcontroller profile (Cortex-M) cores. The armv4_5_run_algorithm() declaration was moved too, even though it's not yet as generic as it probably ought to be. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
2009-12-04rename nand.h to flash//nand/core.hZachary T Welch
Rename nand.h as flash/nand/core.h, chase consumers. The public APIs need to be sorted out with imp.h, but this allows other changes to begin improving the separation between policy and mechanism. Moves #include <target/target.h> and #include "driver.h" into the internal headers or source files, removing it from <flash/nand/core.h>.
2009-12-04move remaining nand helper filesZachary T Welch
Move remaining NAND implementation files into src/flash/nand/.
2009-12-04split nand.c into nand/{core,fileio,tcl}.cZachary T Welch
Moves commands into nand/tcl.c and core implementation to 'nand/core.c' and 'nand/fileio.c'. Eliminates 'flash/nand.c'. Adds 'nand/imp.h' to share routines between TCL commands and core.
2009-12-04split NAND driver handling into nand/driver.[ch]Zachary T Welch
This work parallels the NOR directory, encapsulating the NAND drivers into a separate file. This takes an extra step by encapsulating the type of data structure used to manage the drivers, allowing it to be changed from an array to a dynamic list in the future.
2009-12-03ARM NAND I/O interface updateDean Glazeski
Modify the arm_nand_data struct to better support both read and write operations while using the same struct. An additional field was added, and initialized, to record the last operation so that the correct code can be loaded to the working area.

2009-12-03remove tertiary include pathsZachary T Welch
With all #include directives converted, we only need to have the top-level src/ directory in the search path.
2009-12-03change #include "../hello.h" to "hello.h"Zachary T Welch
Before we can -I the top-level src/ directory alone, references to "hello.h" must be updated. This is an internal header, so it does not need angle brackets.
2009-12-03change #include "s3c24xx_regs.h" to <flash/nand/s3c24xx_regs.h>Zachary T Welch
Changes from the flat namespace to heirarchical one. Instead of writing: #include "s3c24xx_regs.h" the following form should be used. #include <flash/nand/s3c24xx_regs.h> The exception is from .c files in the same directory.
2009-12-03change #include "nand.h" to <flash/nand.h>Zachary T Welch
Changes from the flat namespace to heirarchical one. Instead of writing: #include "nand.h" the following form should be used. #include <flash/nand.h> The exception is from .c files in the same directory.

These headers need minor tweaks to paves the way for wholesale scripted coversion of the header files.
2009-12-03allow #include directives to use module nameZachary T Welch
Includes the src directory in the search path, so header files may be migrated from: #include "foo.h" to #include <module/foo.h> which is more conducive for installation.
2009-12-02move nand drivers to src/flash/nand/Zachary T Welch
