* | mtd: vf610_nfc: specify transfer size before each transferStefan Agner2015-03-30-8/+17
| | | | | | | | | | | | | | | | | | | | Testing showed, that commands like STATUS made the buffer dirty when executed with NFC_SECSZ set to the page size. It looks like the controller transfers bogus data when this register is configured. When setting it to 0, the buffer does not get altered while the status command still seems to work flawless.

* | mtd: vf610_nfc: mark page as dirty on block eraseStefan Agner2015-03-30-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The driver tries to re-use the page buffer by storing the page number of the current page in the buffer. The page is only read if the requested page number is not currently in the buffer. When a block is erased, the page number is marked as invalid if the erased page equals the one currently in the cache. However, since a erase block consists of multiple pages, also other page numbers could be affected. The commands to reproduce this issue (on a written page): > nand dump 0x800 > nand erase 0x0 0x20000 > nand dump 0x800 The second nand dump command returns the data from the buffer, while in fact the page is erased (0xff). Avoid the hassle to calculate whether the page is affected or not, but set the page buffer unconditionally to invalid instead. Signed-off-by: Stefan Agner <stefan@agner.ch>
* | nand: yaffs: Remove the "nand write.yaffs" commandPeter Tyser2015-03-30-65/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This command is only enabled by one board, complicates the NAND code, and doesn't appear to have been functioning properly for several years. If there are no bad blocks in the NAND region being written nand_write_skip_bad() will take the shortcut of calling nand_write() which bypasses the special yaffs handling. This causes invalid YAFFS data to be written. See http://lists.denx.de/pipermail/u-boot/2011-September/102830.html for an example and a potential workaround. U-Boot still retains the ability to mount and access YAFFS partitions via CONFIG_YAFFS2. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>

* omap: gpmc: 'nandecc sw' can use HAM1 or BCH8Ash Charles2015-03-05-1/+11
| | | | | | | | | | | | | | | The 'nandecc sw' command selects a software-based error correction algorithm. By default, this is OMAP_ECC_HAM1_CODE_SW but some platforms use OMAP_ECC_BCH8_CODE_HW_DETECTION_SW as their software-based correction algorithm. Allow a user to be specific e.g. # nandecc sw <hamming|bch8> where 'hamming' is still the default. Note: we don't just use CONFIG_NAND_OMAP_ECCSCHEME as it might be set to a hardware-based ECC scheme---a little strange when the user has requested 'sw' ECC.

* mtd: nand: omap_gpmc: Make ready/busy pins configurableMichal Sojka2015-03-05-2/+14
| | | | | | | | | | | | | | | | | | | | | | | Commit fb384c4720ca7496775d6578f184bf628db73456 introduced the use of WAIT0 pin for determining whether the NAND is ready or not. This only works if all NAND chips are connected to WAIT0. If some chips are connected to the other available pin WAIT1, nand_wait() does not really wait and prints a WARN_ON message. This patch allows the board to provide configuration of which chip is connected to which WAITx signal. For example, one can define in include/configs/foo.h: #define CONFIG_NAND_OMAP_GPMC_WSCFG 0,0,1,1 This would mean that chips using to CS0 and 1 are connected to WAIT0 and chips with CS2 and 3 are connected to WAIT1.

* kconfig: remove unneeded dependency on !SPL_BUILDMasahiro Yamada2015-02-24-4/+0

* kconfig: switch to single .config configurationMasahiro Yamada2015-02-24-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When Kconfig for U-boot was examined, one of the biggest issues was how to support multiple images (Normal, SPL, TPL). There were actually two options, "single .config" and "multiple .config". After some discussions and thought experiments, I chose the latter, i.e. to create ".config", "spl/.config", "tpl/.config" for Normal, SPL, TPL, respectively. It is true that the "multiple .config" strategy provided us the maximum flexibility and helped to avoid duplicating CONFIGs among Normal, SPL, TPL, but I have noticed some fatal problems: [1] It is impossible to share CONFIG options across the images. If you change the configuration of Main image, you often have to adjust some SPL configurations correspondingly. Currently, we cannot handle the dependencies between them. It means one of the biggest advantages of Kconfig is lost. [2] It is too painful to change both ".config" and "spl/.config". Sunxi guys started to work around this problem by creating a new configuration target. Commit cbdd9a9737cc (sunxi: kconfig: Add %_felconfig rule to enable FEL build of sunxi platforms.) added "make *_felconfig" to enable CONFIG_SPL_FEL on both images. Changing the configuration of multiple images in one command is a generic demand. The current implementation cannot propose any good solution about this. [3] Kconfig files are getting ugly and difficult to understand. Commit b724bd7d6349 (dm: Kconfig: Move CONFIG_SYS_MALLOC_F_LEN to Kconfig) has sprinkled "if !SPL_BUILD" over the Kconfig files. [4] The build system got more complicated than it should be. To adjust Linux-originated Kconfig to U-Boot, the helper script "scripts/multiconfig.sh" was introduced. Writing a complicated text processor is a shell script sometimes caused problems. Now I believe the "single .config" will serve us better. With it, all the problems above would go away. Instead, we will have to add some CONFIG_SPL_* (and CONFIG_TPL_*) options such as CONFIG_SPL_DM, but we will not have much. Anyway, this is what we do now in scripts/Makefile.spl. I admit my mistake with my apology and this commit switches to the single .config configuration. It is not so difficult to do that: - Remove unnecessary processings from scripts/multiconfig.sh This file will remain for a while to support the current defconfig format. It will be removed after more cleanups are done. - Adjust some makefiles and Kconfigs - Add some entries to include/config_uncmd_spl.h and the new file scripts/Makefile.uncmd_spl. Some CONFIG options that are not supported on SPL must be disabled because one .config is shared between SPL and U-Boot proper going forward. I know this is not a beautiful solution and I think we can do better, but let's see how much we will have to describe them. - update doc/README.kconfig More cleaning up patches will follow this.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At present we go through various contortions to store the SPI slave's chip select in its private data. This only exists when the slave is active so must be set up when it is probed. Until the device is probed we don't actually know what chip select it will appear on. However, now that we can support per-child platform data, we can use that instead. This allows us to set up the chip select when the child is bound, and avoid the messy contortions. Unfortunately this is a fairly large change and it seems to be difficult to break it down further. Signed-off-by: Simon Glass <sjg@chromium.org>

| | | | | | | | | | | | | | | | | | | | | | | | | Enable GPMC's prefetch feature for NAND access. This speeds up NAND read access a lot by pre-fetching contents in the background and reading them through the FIFO address. The current implementation has two limitations: a) it only works in 8-bit mode b) it only supports read access Both is easily fixable by someone who has hardware to implement it. Note that U-Boot code uses non word-aligned buffers to read data into, and request read lengths that are not multiples of 4, so both partial buffers (head and tail) have to be addressed.

| | | | | | | | | | | | | | | | | Currently, "nand scrub" runs chip->scan_bbt at the end of nand_erase_opts() even if NAND_SKIP_BBTSCAN flag is set. It violates the intention of NAND_SKIP_BBTSCAN.

Also, unset NAND_BBT_SCANNED flag instead of running chip->scan_bbt() right after scrub. We can be lazier here because the BBT is scanned at the next call of nand_block_checkbad().

It causes recursion if scan_bbt does not find a flash based BBT and tries to write one, and the attempt to erase the BBT area causes a bad block check.

* | linux/kernel.h: sync min, max, min3, max3 macros with LinuxMasahiro Yamada2014-11-23-4/+5
|/ | | | | | | | | | | | | | | | | | | | U-Boot has never cared about the type when we get max/min of two values, but Linux Kernel does. This commit gets min, max, min3, max3 macros synced with the kernel introducing type checks. Many of references of those macros must be fixed to suppress warnings. We have two options: - Use min, max, min3, max3 only when the arguments have the same type (or add casts to the arguments) - Use min_t/max_t instead with the appropriate type for the first argument Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com> Acked-by: Pavel Machek <pavel@denx.de> Acked-by: Lukasz Majewski <l.majewski@samsung.com> Tested-by: Lukasz Majewski <l.majewski@samsung.com> [trini: Fixup arch/blackfin/lib/string.c] Signed-off-by: Tom Rini <trini@ti.com>
