| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

This patch changes this function to return NULL pointer in such a case, which is more correct behaviour. The function flash_protect_default() calls flash_protect() immediately after flash_get_info() invocation. With this correction, flash_protect() function would be able to return soon, for NULL flash_info. Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com> Signed-off-by: Stefan Roese <sr@denx.de>

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | Packed structure cfi_qry contains unaligned 16- and 32-bits members, accessing which causes problems when cfi_flash driver is compiled with -munaligned-access option: flash initialization hangs, probably due to data error. Since the structure is supposed to replicate the actual data layout in CFI Flash chips, the alignment issue can't be fixed in the structure. So, unaligned fields need using of explicit unaligned access macros.

* | | mtd: nand: add driver for diskonchip g4 nand flashMike Dunn2013-05-05-0/+1252
| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a driver for the diskonchip G4 nand flash device. It is based on the driver from the linux kernel. This also includes a separate SPL driver. A separate SPL driver is used because the device operates in a different mode (reliable mode) when loading a boot image, and also because the storage format of the boot image is different from normal data (pages are stored redundantly). The SPL driver basically mimics how a typical IPL reads data from the device. The special operating mode and storage format are used to compensate for the fact that the IPL does not contain the BCH ecc decoding algorithm (due to size constraints). Although the u-boot SPL *could* use ecc, it operates like an IPL for the sake of simplicity and uniformity, since the IPL and SPL share the task of loading the u-boot image. As a side benefit, the SPL driver is very small. [port from linux kernel 3.4 commit 570469f3bde7f71cc1ece07a18d54a05b6a8775d] Signed-off-by: Mike Dunn <mikedunn@newsguy.com>

If it is defined in the board file, then consider 16-bit NAND bus-width, otherwise assume 8-bit NAND is used.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We make these two functions take a size_t pointer to how much space was used on NAND to read or write the buffer (when reads/writes happen) so that bad blocks can be accounted for. We also make them take an loff_t limit on how much data can be read or written. This means that we can now catch the case of when writing to a partition would exceed the partition size due to bad blocks. To do this we also need to make check_skip_len count not just complete blocks used but partial ones as well. All callers of nand_(read|write)_skip_bad are adjusted to call these with the most sensible limits available. The changes were started by Pantelis and finished by Tom.

Addressing for 8 and 16 bits is almost identical except in the 16-bit case the LSB of the address is always 0. The confusion arose because the addresses in the datasheet for 16-bit mode are word addresses but this code assumed it was byte addresses. I have only been able to test this on our Octeon boards which use either an 8-bit or 16-bit bus. I have not tested the case where there's an 8-bit part on a 16-bit bus. This patch also adds some delays as suggested by Spansion. If a part can be both 8 and 16-bits, it forces it to work in 8-bit mode if an 8-bit bus is detected. Apart from the pulled changes, fixed few minor code cleanups and tested on 256M29EW, 512M29EW flashes.

| * am33xx: Add required includes to some omap/am33xx codeTom Rini2013-03-24-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | - In arch/arm/cpu/armv7/omap-common/timer.c, drivers/mtd/nand/omap_gpmc.c and drivers/net/cpsw.c add #include files that the driver needs but had been relying on <config.h> to bring in. - In arch/arm/cpu/armv7/omap-common/lowlevel_init.S add <config.h> - In am335x_evm.h and pcm051.h don't globally include <asm/arch/hardware.h> and <asm/arch/cpu.h> but just <asm/arch/omap.h> as that is the only include which defines things the config uses.

* | sf: Enable FDT-based configuration and memory mappingSimon Glass2013-03-19-1/+45
| | | | | | | | | | | | | | Enable device tree control of SPI flash, and use this to implement memory-mapped SPI flash, which is supported on Intel chips. Signed-off-by: Simon Glass <sjg@chromium.org>
* | sf: Respect maximum SPI write sizeSimon Glass2013-03-19-2/+8
| | | | | | | | | | | | | | | | Some SPI flash controllers (e.g. Intel ICH) have a limit on the number of bytes that can be in a write transaction. Support this by breaking the writes into multiple transactions. Signed-off-by: Simon Glass <sjg@chromium.org>
* | sf: Use spi_flash_alloc() in each SPI flash driverSimon Glass2013-03-19-52/+8
| | | | | | | | | | | | | | | | Rather than each device having its own way to allocate a SPI flash structure, use the new allocation function everywhere. This will make it easier to extend the interface without breaking devices. Signed-off-by: Simon Glass <sjg@chromium.org>
* | sf: Add spi_flash_alloc() to create a new SPI flash structSimon Glass2013-03-19-0/+25
|/ | | | | | | | | | At present it is difficult to extend the SPI flash structure since all devices allocate it themselves, and few of them zero all fields. Add a new function spi_flash_alloc() which can be used by SPI devices to perform this allocation, and thus ensure that all devices can better cope with SPI structure changes.
