2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
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>
2018-04-03mtd: nand: sunxi: fix ECC strength choiceMiquel Raynal
When the requested ECC strength does not exactly match the strengths supported by the ECC engine, the driver is selecting the closest strength meeting the 'selected_strength > requested_strength' constraint. Fix the fact that, in this particular case, ecc->strength value was not updated to match the 'selected_strength'. For instance, one can encounter this issue when no ECC requirement is filled in the device tree while the NAND chip minimum requirement is not a strength/step_size combo natively supported by the ECC engine.

2017-12-04mtd: nand: Rename nand.h into rawnand.hMasahiro Yamada
This header was renamed to rawnand.h in Linux. The following is the corresponding commit in Linux. commit d4092d76a4a4e57b65910899948a83cc8646c5a5 Author: Boris Brezillon <boris.brezillon@free-electrons.com> Date: Fri Aug 4 17:29:10 2017 +0200 mtd: nand: Rename nand.h into rawnand.h We are planning to share more code between different NAND based devices (SPI NAND, OneNAND and raw NANDs), but before doing that we need to move the existing include/linux/mtd/nand.h file into include/linux/mtd/rawnand.h so we can later create a nand.h header containing all common structure and function prototypes.

2017-06-01dm: gpio: Add live tree supportSimon Glass
Add support for requesting GPIOs with a live device tree. This involves adjusting the function signature for the legacy function gpio_request_by_name_nodev(), so fix up all callers.

2016-07-24mtd: nand: Add the sunxi NAND controller driverBoris Brezillon
We already have an SPL driver for the sunxi NAND controller, now add the normal/standard one. The source has been copied from Linux 4.6 with a few changes to make it work in u-boot. Signed-off-by: Boris Brezillon <boris.brezillon@free-electrons.com> Acked-by: Hans de Goede <hdegoede@redhat.com>
