* MLK-10467 mtd:spi Add ATMEL AT45DB021E supportPeng Fan2015-04-29-2/+98
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch is to add atmel AT45DB021E spi flash support. Since this flash is different from the spi flash that we previous use such as m25p32 and spanion spi nor flashes, pieces of code are added. 1. The default page size is 264 bytes, but the mtd/spi framework can not handle such page. So we need to configure the page size from 264 to 256 bytes. Page Size command seq “Power of 2” binary page size (256 bytes)| 3Dh 2Ah 80h A6h DataFlash page size (264 bytes) | 3Dh 2Ah 80h A7h And when probe the flash, configure the flash to 256 bytes page size, if the page size is already 256bytes, just return and do not configure it again. The page size configuration times is only about 10000, so to avoid configuring it each time. 2. Add the flash params in sf_params.c. 3. This flash support 2K block erase, add this flag. 4. The status command is 0xD7, different from others. It's polling status bit is Bit 7 -> 0 Device is busy with an internal operation. -> 1 Device is ready. This patch has been tested on mx7d 19x19 ddr3 arm2 board. And tested on mx7d 12x12 lpddr3 board. All works fine. Note: Since this flash is only 256KB, we can not test spi boot on mx7d 19x19 arm2 board. If want to test this flash, open CONFIG_SYS_USE_SPINOR.

* MLK-10774-36 mtd: spi: check return value of spi_setup_slavePeng Fan2015-04-29-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Need to check value of spi_setup_slave and spi_setup_slave_fdt. If their return value 'bus' is NULL, there is no need to pass it to following spi_flash_probe_tail. If 'bus' is null, the original function flow is as following: spi_flash_probe |->spi_setup_slave |->spi_probe_bus_tail |->spi_flash_probe_slave |->spi_free_slave Alougth check the pointer in spi_free_slave is ok, checking the return value of spi_setup_slave and spi_setup_slave_fdt is better.

* | 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: switch to single .config configurationMasahiro Yamada2015-02-24-1/+1

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.

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.

However some SPI controllers do not support the word program command (like the Intel ICH 7), the byte programm command (02h) has to be used.

* sf: Fix look for the fastest read commandJagannadha Sutradharudu Teki2014-12-13-56/+60
| | | | | | | | | | | Few of the spi controllers are only supports array slow read which is quite different behaviour compared to others. So this fix on sf will correctly handle the slow read supported controllers. Signed-off-by: Jagannadha Sutradharudu Teki <jagannadh.teki@gmail.com> Tested-by: Bin Meng <bmeng.cn@gmail.com>

* arm: ls102xa: Add NAND boot support for LS1021AQDS boardAlison Wang2014-12-11-0/+10
| | | | | | | | | | | This patch adds NAND boot support for LS1021AQDS board. SPL framework is used. PBL initialize the internal RAM and copy SPL to it, then SPL initialize DDR using SPD and copy u-boot from NAND flash to DDR, finally SPL transfer control to u-boot.

* mtd: nand: omap_gpmc: Always use ready/busy pinStefan Roese2014-12-04-5/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The functions to detect the state of the ready / busy signal is already available but only used in the SPL case. Lets use it always, also for the main U-Boot. As all boards should have this HW connection. Testing on Siemens Draco (am335x) showed a small perfomance gain by using this ready pin to detect the NAND chip state. Here the values tested on Draco with Hynix 4GBit NAND: Without NAND ready pin: U-Boot# time nand read 80400000 0 400000 NAND read: device 0 offset 0x0, size 0x400000 4194304 bytes read: OK time: 2.947 seconds, 2947 ticks With NAND ready pin: U-Boot# time nand read 80400000 0 400000 NAND read: device 0 offset 0x0, size 0x400000 4194304 bytes read: OK time: 2.795 seconds, 2795 ticks So an increase of approx. 5%.

| | | | | | | | | | | | This patch disables subpage writes for vf610_nfc nand driver. This is required, as without this fix, writing unaligned u-boot images with DFU results in a hang. Trying to write unalgined binary images also results in a hang, without disabling subpage writes. Patch has been tested on a Colibri VF61 module.

* mtd: denali: set some registers after nand_scan_ident()Masahiro Yamada2014-11-26-0/+11
| | | | | | | | | | | | | | | | | Some but not all of implementations of the Denali NAND controller have hardware circuits to detect the device parameters such as page_size, erase_size, etc. Even on those SoCs with such hardware supported, the hardware is known to detect wrong parameters for some nasty (almost buggy) NAND devices. The device parameters detected during nand_scan_ident() are more trustworthy. This commit sets some hardware registers to mtd->pagesize, mtd->oobsize, etc. in the code between nand_scan_ident() and nand_scan_tail().

* mtd: denali: use CONFIG_SYS_NAND_SELF_INITMasahiro Yamada2014-11-26-40/+93
| | | | | | | | | | | | | | | | Some variants of the Denali NAND controller need some registers set up based on the device information that has been detected during nand_scan_ident(). CONFIG_SYS_NAND_SELF_INIT has to be defined to insert code between nand_scan_ident() and nand_scan_tail(). It is also helpful to reduce the difference between this driver and its Linux counterpart because this driver was ported from Linux. Moreover, doc/README.nand recommends to use CONFIG_SYS_NAND_SELF_INIT.
