2018-09-20mtd: move NAND files into a raw/ subdirectoryMiquel Raynal1-175/+0
NAND flavors, like serial and parallel, have a lot in common and would benefit to share code. Let's move raw (parallel) NAND specific code in a raw/ subdirectory, to ease the addition of a core file in nand/ and the introduction of a spi/ subdirectory specific to SPI NANDs.

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini1-2/+1
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>
2018-04-27Remove unnecessary instances of DECLARE_GLOBAL_DATA_PTRTom Rini1-2/+0
We have a large number of places where while we historically referenced gd in the code we no longer do, as well as cases where the code added that line "just in case" during development and never dropped it. Signed-off-by: Tom Rini <trini@konsulko.com>
2017-07-11mtd: nand: make nand_info array staticGrygorii Strashko1-1/+1
Make make nand_info array static, since all direct users of nand_info array have been converted to use get_nand_dev_by_index() API. Signed-off-by: Grygorii Strashko <grygorii.strashko@ti.com>
2017-07-11cmd: nand: abstract global variable usage for dm conversionMugunthan V N1-6/+15
nand_info is used all over the file so abstract it with get_nand_dev_by_index() which will help for DM conversion. Signed-off-by: Mugunthan V N <mugunthanvnm@ti.com> Signed-off-by: Grygorii Strashko <grygorii.strashko@ti.com>
2017-03-28mtd: nand: remove nand size print from nand_init functionHou Zhiqiang1-2/+5
Add nand_size() function to move the nand size print into initr_nand(). Remove nand size print from nand_init() to allow other function to call nand_init() without printing nand size. Signed-off-by: Hou Zhiqiang <Zhiqiang.Hou@nxp.com> Reviewed-by: York Sun <york.sun@nxp.com>
2017-03-28mtd: nand: add initialization flagHou Zhiqiang1-0/+10
Add initialization flag to avoid initializing NAND Flash multiple times, otherwise it will calculate a wrong total size. Signed-off-by: Hou Zhiqiang <Zhiqiang.Hou@nxp.com> Reviewed-by: York Sun <york.sun@nxp.com>
2016-06-09nand: add nand mtd concat supportHeiko Schocher1-0/+41
add for nand devices mtd concat support. Generic MTD concat support is already ported to mainline, and used in the cfi_mtd driver. This patch adds it similiar for nand devices. Signed-off-by: Heiko Schocher <hs@denx.de>
2016-06-03mtd: nand: Add+use mtd_to/from_nand and nand_get/set_controller_dataScott Wood1-3/+2
These functions are part of the Linux 4.6 sync. They are being added before the main sync patch in order to make it easier to address the issue across all NAND drivers (many/most of which do not closely track their Linux counterparts) separately from other merge issues. Signed-off-by: Scott Wood <oss@buserror.net>
2016-06-03nand: Embed mtd_info in struct nand_chipScott Wood1-8/+19
nand_info[] is now an array of pointers, with the actual mtd_info instance embedded in struct nand_chip. This is in preparation for syncing the NAND code with Linux 4.6, which makes the same change to struct nand_chip. It's in a separate commit due to the large amount of changes required to accommodate the change to nand_info[]. Signed-off-by: Scott Wood <oss@buserror.net>
2016-06-03mtd: nand: Remove nand_info_t typedefScott Wood1-1/+1
This typedef serves no purpose other than causing confusion with struct nand_chip. Signed-off-by: Scott Wood <oss@buserror.net>
2016-01-19Add more SPDX-License-Identifier tagsTom Rini1-16/+1
In a number of places we had wordings of the GPL (or LGPL in a few cases) license text that were split in such a way that it wasn't caught previously. Convert all of these to the correct SPDX-License-Identifier tag. Signed-off-by: Tom Rini <trini@konsulko.com>
2012-01-26nand: Introduce CONFIG_SYS_NAND_SELF_INITScott Wood1-37/+59
This allows a driver to run code between nand_scan_ident() and nand_scan_tail(), among other things. See the additions to doc/README.nand for details. To allow a gradual transition, Boards that don't set CONFIG_SYS_NAND_SELF_INIT will still be initialized the old way, but new drivers should not require this, and existing drivers should be converted when convenient.

2011-01-12nand: fix bug with multiple NAND devices if CONFIG_MTD_DEVICE is defined.Alexander Holler1-1/+1
The variable i has to be static, otherwise it would be always zero. Signed-off-by: Alexander Holler <holler@ahsoftware.de>
2010-10-29Replace CONFIG_RELOC_FIXUP_WORKS by CONFIG_NEEDS_MANUAL_RELOCWolfgang Denk1-1/+1
By now, the majority of architectures have working relocation support, so the few remaining architectures have become exceptions. To make this more obvious, we make working relocation now the default case, and flag the remaining cases with CONFIG_NEEDS_MANUAL_RELOC.

2009-10-03Conditionally perform common relocation fixupsPeter Tyser1-0/+2
Add #ifdefs where necessary to not perform relocation fixups. This allows boards/architectures which support relocation to trim a decent chunk of code. Note that this patch doesn't add #ifdefs to architecture-specific code which does not support relocation. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>
2009-06-12mtd: Introduce CONFIG_MTD_DEVICE to select compilation of mtdcore.oStefan Roese1-1/+1
This new define enables mtdcore.c compilation and with this we can select the MTD device infrastructure needed for the reworked mtdparts command. We now have the 2 MTD infrastructure defines, CONFIG_MTD_DEVICE and CONFIG_MTD_PARTITIONS. CONFIG_MTD_DEVICE is needed (as explained above) for the "mtdparts" command and CONFIG_MTD_PARTITIONS is needed for UBI.

2009-04-28mtd: nand/onenand: Register mtd device upon device scanningStefan Roese1-0/+12
With this patch the NAND and OneNAND devices are registered in the MTD subsystem and can then be referenced by the mtdcore code (e.g. get_mtd_device_nm()). This is needed for the new "ubi part" command syntax without the flash type parameter (nor|nand|onenand). Signed-off-by: Stefan Roese <sr@denx.de>
2009-03-23Enable multi chip support in the NAND layerWolfgang Grandegger1-1/+5

2009-01-23NAND: move board_nand_init to nand.hMike Frysinger1-2/+0
Rather than putting the function prototype for board_nand_init() in the one place where it gets called, put it into nand.h so that every place that also defines it gets the prototype. Otherwise, errors can go silently unnoticed such as using the wrong return value (void rather than int) when defining the function.

2008-10-14Fix the NAND size overflow issue.Jason Jin1-2/+2
When the total size of all NAND devices exceeds 4 GiB, the size will overflow. This patch tries to fix this. Note that we still have a problem when a single NAND device is bigger than 4 GiB: then the overflow would actually happen earlier, i. e. when storing the size in nand_info[].size, as nand_info[].size is an "u_int32_t".
