2018-09-20mtd: move NAND files into a raw/ subdirectoryMiquel Raynal1-75/+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 Rini1-3/+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>

2017-08-30mtd: nand: denali_dt: add a DT driverMasahiro Yamada1-0/+1
A patch for NAND uclass support was proposed about half a year ago: https://patchwork.ozlabs.org/patch/722282/ It was not merged and I do not see on-going work for this. Without DM-based probing, we need to set up pinctrl etc. in an ad-hoc way and give lots of crappy CONFIG options for base addresses and properties, which are supposed to be specified by DT. This is painful. This commit just provides a probe hook to retrieve "reg" from DT and allocate private data in a DM manner. This DT driver is not essentially a NAND driver, in fact it is (ab)using UCLASS_MISC. Once UCLASS_NAND is supported, it would be possible to migrate to it.

We eventually want to add full nand support, since it makes no sense to build SPL with nand support and u-boot without, or the other way around, a single option will suffice. Renaming the Kconfig option now makes things easier when we add full nand support in the future.

2015-08-12nand: lpc32xx: add SLC NAND controller supportVladimir Zapolskiy1-0/+1
The change adds support of LPC32xx SLC NAND controller. LPC32xx SoC has two different mutually exclusive NAND controllers to communicate with single and multiple layer chips. This simple driver allows to specify NAND chip timings and defines custom read_buf()/write_buf() operations, because access to 8-bit data register must be 32-bit aligned. Support of hardware ECC calculation is not implemented (data correction is always done by software), since it requires a working DMA engine. The driver can be included to an SPL image.

2013-05-05mtd: nand: add driver for diskonchip g4 nand flashMike Dunn1-0/+2
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>
