* mtd: nand: Sync with Linux v4.6Scott Wood2016-06-03-15/+15
| | | | | | | | | | | | Updates the NAND code to match Linux v4.6. The previous sync was from Linux v4.1 in commit d3963721d93fafa. Note that none of the individual NAND drivers tracked Linux closely enough to be synced themselves, other than manually applying a few cross-tree changes.

* mtd: nand: Add+use mtd_to/from_nand and nand_get/set_controller_dataScott Wood2016-06-03-16/+16
| | | | | | | | | 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.

* nand: Sync with Linux v4.1Scott Wood2015-08-25-15/+16
| | | | | | | | | | | Update the NAND code to match Linux v4.1. The previous sync was from Linux v3.15 in commit 4e67c57125290b25. CONFIG_SYS_NAND_RESET_CNT is removed, as the upstream Linux code now has its own timeout. Plus, CONFIG_SYS_NAND_RESET_CNT was undocumented and not selected by any board.

* mtd: Introduce mtd_block_isreserved()Ezequiel Garcia2015-08-25-0/+14
| | | | | | | | | | | | | | | | In addition to mtd_block_isbad(), which checks if a block is bad or reserved, it's needed to check if a block is reserved only (but not bad). This commit adds an MTD interface for it, in a similar fashion to mtd_block_isbad(). While here, fix mtd_block_isbad() so the out-of-bounds checking is done before the callback check.

* kbuild: force to define __UBOOT__ in all the C sourcesMasahiro Yamada2014-09-16-1/+0
| | | | | | | | | | | | | | | | | | | | | | | U-Boot has imported various source files from other projects, mostly Linux. Something like #ifdef __UBOOT__ [ modification for U-Boot ] #else [ original code ] #endif is an often used strategy for clarification of adjusted parts, that is, easier re-sync in future. Instead of defining __UBOOT__ in each source file, passing it from the top Makefile would be easier.

* mtd: resync with Linux-3.7.1Sergey Lapin2013-05-31-436/+386
| | | | | | | | | | | | | | | | | | | | | | This patch is essentially an update of u-boot MTD subsystem to the state of Linux-3.7.1 with exclusion of some bits: - the update is concentrated on NAND, no onenand or CFI/NOR/SPI flashes interfaces are updated EXCEPT for API changes. - new large NAND chips support is there, though some updates have got in Linux-3.8.-rc1, (which will follow on top of this patch). To produce this update I used tag v3.7.1 of linux-stable repository. The update was made using application of relevant patches, with changes relevant to U-Boot-only stuff sticked together to keep bisectability. Then all changes were grouped together to this patch.

* nand: remove dead code and suspend/resumeScott Wood2010-10-11-19/+0
| | | | | | | | | | | | | | | Get rid of the several "#if 0" sections that were keeping around Linux code that isn't relevant to U-Boot. Besides cluttering the code, these sections make tracking upstream changes harder, rather than easier. It's easy to discard obviously irrelevant diff hunks that patch rejects, but it's not as easy to notice hunks that apply cleanly to the #if 0 section, but *are* relevant to U-Boot and require modification elsewhere. Also remove suspend/resume, as this is not applicable to U-Boot. Removal saves 232 bytes on powerpc.

* NAND: Update to support 64 bit device sizeSandeep Paulraj2009-11-13-18/+23

* NAND: sync with 2.6.27Scott Wood2008-10-29-2/+0
| | | | | | | | | | | | | This brings the core NAND code up to date with the Linux kernel. Since there were several drivers in Linux as of the last update that are not in u-boot, I'm not bringing over new drivers that have been added since in the absence of an interested party. I did not update OneNAND since it was recently synced by Kyungmin Park, and I'm not sure exactly what the common ancestor is. Signed-off-by: Scott Wood <scottwood@freescale.com>

* Update MTD to that of Linux 2.6.22.1William Juul2008-08-12-180/+368
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
* NAND: Rename DEBUG to MTDDEBUG to avoid namespace pollution.Scott Wood2008-07-09-2/+2
| | | | | | | | | This is particularly problematic now that non-NAND-specific code is including <nand.h>, and thus all debugging code is being compiled regardless of whether it was requested, as reported by Scott McNutt <smcnutt@psyent.com>. Signed-off-by: Scott Wood <scottwood@freescale.com>
* Big white-space cleanup.Wolfgang Denk2008-05-21-4/+4
| | | | | | | | | | | This commit gets rid of a huge amount of silly white-space issues. Especially, all sequences of SPACEs followed by TAB characters get removed (unless they appear in print statements). Also remove all embedded "vim:" and "vi:" statements which hide indentation problems. Signed-off-by: Wolfgang Denk <wd@denx.de>
