* NAND: Do not write or read a whole block if it is larger than the environmentGuennadi Liakhovetski2008-08-12-9/+9
| | | | | | | | Environment can be smaller than NAND block size, do not need to read a whole block and minimum for writing is one page. Also remove an unused variable. Signed-off-by: Guennadi Liakhovetski <lg@denx.de> Signed-off-by: Scott Wood <scottwood@freescale.com>

* NAND: Scan bad blocks lazily.Ilya Yanok2008-08-12-3/+9
| | | | | | | | | | Rather than scanning on boot, scan upon the first attempt to check the badness of a block. This speeds up boot when not using NAND, and reduces the likelihood of needing to reflash via JTAG if NAND becomes nonfunctional.

* NAND read/write fixScott Wood2008-08-12-611/+194

* NAND: Always skip blocks on read/write/boot.Scott Wood2008-08-12-38/+26
| | | | | | | Use of the non-skipping versions was almost always (if not always) an error, and no valid use case has been identified. Signed-off-by: Scott Wood <scottwood@freescale.com>

* fsl_elbc_nand: Hard-code the FBAR/FPAR split.Scott Wood2008-08-12-3/+2
| | | | | | | | The hardware has separate registers for block and page-within-block, but the division between the two has no apparent relation to the actual erase block size of the NAND chip. Signed-off-by: Scott Wood <scottwood@freescale.com>
* fsl_elbc_nand: workaround for hangs during nand writeAnton Vorontsov2008-08-12-1/+10
| | | | | | | | Using current driver elbc sometimes hangs during nand write. Reading back last byte helps though (thanks to Scott Wood for the idea). Signed-off-by: Anton Vorontsov <avorontsov@ru.mvista.com> Signed-off-by: Scott Wood <scottwood@freescale.com>
* Freescale eLBC FCM NAND driverScott Wood2008-08-12-0/+760
| | | | | | | | This is a driver for the Flash Control Machine of the enhanched Local Bus Controller found on some Freescale chips (such as the mpc8313 and the mpc8379). Signed-off-by: Scott Wood <scottwood@freescale.com>
* Don't panic if a controller driver does ecc its own way.Scott Wood2008-08-12-2/+6
| | | | | | | | | | | | Some hardware, such as the enhanced local bus controller used on some mpc83xx chips, does ecc transparently when reading and writing data, rather than providing a generic calculate/correct mechanism that can be exported to the nand subsystem. The subsystem should not BUG() when calculate, correct, or hwctl are missing, if the methods that call them have been overridden. Signed-off-by: Scott Wood <scottwood@freescale.com>
* NAND: Make NAND driver less verbose per defaultStefan Roese2008-08-12-6/+7
| | | | | | | This patch turns off printing of bad blocks per default upon bootup. This can always be shown via the "nand bad" command later. Signed-off-by: Stefan Roese <sr@denx.de>
* NAND: Davinci driver updatesSergey Kubushyn2008-08-12-5/+14
| | | | | | | | | Here comes a trivial patch to cpu/arm926ejs/davinci/nand.c. Unfortunately I don't have hardware handy so I can not test it at the moment but changes are rather trivial so it should work. It would be nice if somebody with a hardware checked it anyways.

* NAND: Change nand_wait_ready() to not call nand_wait()Stefan Roese2008-08-12-1/+10
| | | | | | | | This patch changes nand_wait_ready() to not just call nand_wait(), since this will send a new command to the NAND chip. We just want to wait for the chip to become ready here. Signed-off-by: Stefan Roese <sr@denx.de>

* Update MTD to that of Linux 2.6.22.1William Juul2008-08-12-3243/+4636
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A lot changed in the Linux MTD code, since it was last ported from Linux to U-Boot. This patch takes U-Boot NAND support to the level of Linux 2.6.22.1 and will enable support for very large NAND devices (4KB pages) and ease the compatibility between U-Boot and Linux filesystems. This patch is tested on two custom boards with PPC and ARM processors running YAFFS in U-Boot and Linux using gcc-4.1.2 cross compilers. MAKEALL ppc/arm has some issues: * DOC/OneNand/nand_spl is not building (I have not tried porting these parts, and since I do not have any HW and I am not familiar with this code/HW I think its best left to someone else.) Except for the issues mentioned above, I have ported all drivers necessary to run MAKEALL ppc/arm without errors and warnings. Many drivers were trivial to port, but some were not so trivial. The following drivers must be examined carefully and maybe rewritten to some degree: cpu/ppc4xx/ndfc.c cpu/arm926ejs/davinci/nand.c board/delta/nand.c board/zylonite/nand.c Signed-off-by: William Juul <william.juul@tandberg.com> Signed-off-by: Stig Olsen <stig.olsen@tandberg.com> Signed-off-by: Scott Wood <scottwood@freescale.com>

As this might confuse users (it already confused us), we like to align OneNAND and NAND address handling. The issue is that cmd_onenand.c subtracts the onenand base address from the addresses you type into the u-boot command line so, unlike nand, you can't use addresses relative to the start of the onenand part e.g. this won't work: onenand read 82000000 280000 400000 you have to use: onenand read 82000000 20280000 400000 Looking at recent git, the only board currently using OneNAND is Apollon, and for this the OneNAND base address is 0 (apollon.h) #define CFG_ONENAND_BASE 0x00000000 so patch below won't break any existing boards and will align OneNAND and NAND handling on boards where OneNAND base address is != 0.
