This chip reports CFI 1.3, but the CFI PRI is like CFI 1.1. Add a quirk to pass probe on this chip.

This patch adds (write|read)_buf callbacks to plat_nand. The NAND on the TS-7800 provisioned by the FPGA allows readw() and readl() to be used which gives a 2.5x speed up. To be able to use this from the plat_nand driver a hook for read_buf (and also write_buf whilst we are in there) need to be made available. This patch adds the hook.

Remove some legacy code from the davinci_nand driver, which made cmdlinepart ignore the the MTD ID passed to it. Boards can have multiple NAND chips, and some do (like the DM357 EVM), so this dated hack is undesirable. Correct labels are like "davinci_nand.0" (for chipselect 0).

Minimal support for the 4-bit ECC engine found on DM355, DM365, DA830/OMAP-L137, and similar recent DaVinci-family chips. This is limited to small-page flash for now; there are some page layout issues for large page chips. Note that most boards using this engine (like the DM355 EVM) include 2GiB large page chips. Sanity tested on DM355 EVM after swapping the socketed NAND for a small-page one.

Make the DaVinci NAND driver require platform_data with board-specific configuration. We can't actually do any kind of sane job of configuring it otherwise. Also fix the comment about picking the "best" ECC mode. We can't do those any more; that relied on knowing what kind of CPU we're using (they don't all support 4-bit ECC), and current policy is that drivers not have cpu_is_*() checks.

This file does not define any kernel-userspace API, all it does it defines few helpers for userspace. Instead, userspace should have a private copy of this file. The main (if not the only) user is the mtd-utils package, but it already has a private copy of this file. This patch also removes references to 'jffs2-user.h' from 'Kbuild' and MAINTAINERS' files.

As pointed out by Kay Sievers, the name size limit is gone from the driver-core, and BUS_ID_SIZE is obsolescent. Rather than just papering over the problem by replacing the mtdname array size with an arbitrary '20 + 2', fix the problem properly and handle arbitrary name sizes.

Refering to: http://bugzilla.kernel.org/show_bug.cgi?id=13265 This patch fixes the BUG via replacing global variable reference: kexec_image in machine_kexec() with local variable reference: image, which is more appropriate, and will not be null.

With the introduction of the .brk section, special care must be taken that no unused page table entries remain if _brk_end and _end are separated by a 2M page boundary. cleanup_highmap() runs very early and hence cannot take care of that, hence potential entries needing to be removed past _brk_end must be cleared once the brk allocator has done its job.
