There isn't any benefit to building the uClinux MTD map as a module as the rootfs it requires in order to actually be usable is appended to the kernel image, not the module. No known system builds it this way either, so change the option to "bool". Signed-off-by:

Due to a processor anomaly (05000263 to be exact), most Blackfin parts cannot keep the embedded filesystem image directly after the kernel in RAM. Instead, the filesystem needs to be relocated to the end of memory. As such, we need to tweak the map addr/size during boot for Blackfin systems. This can be done in any early arch/board init code.

The DMAs have different bit sizes on BF52x and BF54x. From the PHRM: "The 16-bit DMA Access Bus (DAB) connects the DMA controller to the on-chip peripherals, PPI, SPI, Ethernet MAC, the SPORTs, NFC, HOSTDP and the UARTs." 32-bit DMA won't work for BF52x. Signed-off-by:

Add optional callback to allow platform to initialize partitions. Static partitions on a nand device could vary depending on the size of the device. This patch allows an optional platform callback to be used to setup this partition information at runtime. Scan order is: 1) chip.part_probe_types 2) chip.set_parts 3) chip.partitions 4) full mtd device (fallback for no partitions) Some of the existing nand drivers could possibly be replaced by the plat_nand driver by using this patch. These include autcpu12.c and ts7250.c drivers. Signed-off-by:

Add optional probe and remove callbacks to the plat_nand driver. Some platforms may require additional setup, such as configuring the memory controller, before the nand device can be accessed. This patch provides an optional callback to handle this setup as well as a callback to teardown the setup. Signed-off-by:

The RAMROOT function was a successful but non-portable attempt to append the root filesystem to the end of the kernel image. The preferred and portable solution is to use an initramfs instead. The only user of this function was the msp71xx configuration in the MIPS architecture; as the use of the RAMROOT has been removed from that configuration, there are no more users, so this code can be removed.

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 depends on "MTD: CFI 1.0 and CFI 1.1" Signed-off-by:

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. Signed-off-by:

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). Signed-off-by:

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. Signed-off-by:

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. Signed-off-by:

Resolve issue noted by Sneha: when computing oobavail from the list of free areas in the OOB, don't assume there will always be an unused slot at the end. With ECC_HW_SYNDROME and 4KiB page chips, it's fairly likely there *won't* be one. Signed-off-by:

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.

1) Move the MEMREADOOB/MEMWRITEOOB compat_ioctl wrappers from fs/compat_ioctl.c into mtdchar.c . Original request was here: http://lkml.org/lkml/2009/4/1/295 2) Add missing COMPATIBLE_IOCTL lines, so that mtd-utils does not error out when running in 64/32 compatibility mode.

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. Signed-off-by: -

This breaks the dilnetpc map driver, but it could be fixed not to use that option. We want to simplify the partition handling, and this is a step towards that. Remove superfluous 'index' field from private struct mtd_part too, while we're at it. Signed-off-by: -
