* lpc3180: LPC3180(LPC3250) SLC driver implementedrichard vegh2010-03-162-9/+441
| | | | | | | | | | | | | | | | 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>
* NAND: lpc3180 crashes on LPC3250richard vegh2010-01-161-13/+38
| | | | | | | | | | | | | 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>
* nand flash support for s3c64xxPeter Korsgaard2010-01-143-0/+79
| | | | | | | | | | | | 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.

* NAND: help/usage/doc updatesDavid Brownell2010-01-083-48/+50
| | | | | | | | | | | | | | 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>
* MinGW build fixesFreddie Chopin2009-12-281-2/+2
| | | | | | | | Print "ssize_t" as "%ld" (+ cast to long) not as "%zu". Official MinGW (gcc 3.4.5) doesn't understand "z" flag. Signed-off-by: Freddie Chopin <freddie_chopin@op.pl> Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>

* AT91SAM9 NAND flash driver.Dean Glazeski2009-12-193-1/+754
| | | | | | | | | | 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.

* NAND write data page refactoring.Dean Glazeski2009-12-182-59/+69
| | | | | | | | | | | 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.

* NAND read data page refactor.Dean Glazeski2009-12-182-45/+25
| | | | | | | | | | | | | | 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).

* add missing call to add new NAND devicesZachary T Welch2009-12-112-0/+4
| | | | | I forgot to add a call to the newly factored nand_device_add(), along with its forward declaration.

* ARM: use <target/arm.h> not armv4_5.hDavid Brownell2009-12-072-2/+2
| | | | | | | | | | | | | | 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>
* rename nand.h to flash//nand/core.hZachary T Welch2009-12-0418-16/+268
| | | | | | | | | 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>.
* move remaining nand helper filesZachary T Welch2009-12-047-2/+606
| | | | Move remaining NAND implementation files into src/flash/nand/.
* split nand.c into nand/{core,fileio,tcl}.cZachary T Welch2009-12-046-0/+1900
| | | | | | | 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.
* split NAND driver handling into nand/driver.[ch]Zachary T Welch2009-12-043-0/+190
| | | | | | | 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.
* ARM NAND I/O interface updateDean Glazeski2009-12-032-0/+2
| | | | | | | | | | | 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.

* remove tertiary include pathsZachary T Welch2009-12-031-6/+1
| | | | | With all #include directives converted, we only need to have the top-level src/ directory in the search path.
* change #include "../hello.h" to "hello.h"Zachary T Welch2009-12-031-0/+2
| | | | | | 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.
* change #include "s3c24xx_regs.h" to <flash/nand/s3c24xx_regs.h>Zachary T Welch2009-12-031-1/+1
| | | | | | | | | | | | 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.
* change #include "nand.h" to <flash/nand.h>Zachary T Welch2009-12-034-4/+4
| | | | | | | | | | | | 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.
* change #include "arm_nandio.h" to <flash/arm_nandio.h>Zachary T Welch2009-12-032-2/+2
| | | | | | | | | | | | Changes from the flat namespace to heirarchical one. Instead of writing: #include "arm_nandio.h" the following form should be used. #include <flash/arm_nandio.h> The exception is from .c files in the same directory.
* change #include "armv4_5.h" to <target/armv4_5.h>Zachary T Welch2009-12-031-1/+1
| | | | | | | | | | | | Changes from the flat namespace to heirarchical one. Instead of writing: #include "armv4_5.h" the following form should be used. #include <target/armv4_5.h> The exception is from .c files in the same directory.
* normalize headers to make changing easierZachary T Welch2009-12-031-1/+1
| | | | | These headers need minor tweaks to paves the way for wholesale scripted coversion of the header files.
* allow #include directives to use module nameZachary T Welch2009-12-031-0/+1
| | | | | | | | | | | | 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.
* move nand drivers to src/flash/nand/Zachary T Welch2009-12-0215-0/+3791
Moves NAND drivers to src/flash/nand/. Adds src/flash/nand/Makefile.am. Builds libocdflashnand.la.
