SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12Z

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

mtd: cfi: Add support for status register polling

2017-09-26T08:57:53Z

The status register is optional in the AMD command sets, but it's presence can be checked by reading out CFI table entry 0xc bit 0. If the register is present, prefer using it's bit 7 to determine if the flash is busy over reading the flash ; this is needed ie. on Hyperflash memories.

cfi_flash: use specific width types for cword

2015-10-27T10:51:53Z

This patch changes the cword union to use specific length types that are architecture indepented. This patch also renames the members of the cword union to represent their usage, i.e.: c -> w8 s -> w16 l -> w32 ll -> w64 Where "w" stands for "width" in bits. I discovered this problem when enabling CFI flash on vexpress64. cword.l was an unsigned long int, but it was intended to be 32 bits wide. Unfortunately, it's 64-bits wide on a 64-bit system, meaning that a 64-bit system fails when attempting to use 32-bit wide CFI flash parts. Similar problems also existed with the other cword sizes.

kbuild: force to define UBOOT in all the C sources

2014-09-16T16:23:56Z

U-Boot has imported various source files from other projects, mostly Linux. Something like #ifdef __UBOOT__ [ modification for U-Boot ] #else [ original code ] #endif is an often used strategy for clarification of adjusted parts, that is, easier re-sync in future. Instead of defining __UBOOT__ in each source file, passing it from the top Makefile would be easier. Signed-off-by: Masahiro Yamada Acked-by: Marek Vasut Acked-by: Heiko Schocher

mtd: move & update nand_ecclayout structure (plus board changes)

2013-11-21T19:32:43Z

nand_ecclayout is present in mtd.h at Linux. Move this structure to mtd.h to comply with Linux. Also, increase the ecc placement locations to 640 to suport device having writesize/oobsize of 8KB/640B. This means that the maximum oobsize has gone up to 640 bytes and consequently the maximum ecc placement locations have also gone up to 640. Changes from Prabhabkar's version (squashed into one patch to preserve bisectability): - Added _LARGE to MTD_MAX_*_ENTRIES This makes the names match current Linux source, and resolves a conflict between http://patchwork.ozlabs.org/patch/280488/ and http://patchwork.ozlabs.org/patch/284513/ The former was posted first and is closer to matching Linux, but unlike Linux it does not add _LARGE to the names. The second adds _LARGE to one of the names, and depends on it in a subsequent patch (http://patchwork.ozlabs.org/patch/284512/). - Made max oobfree/eccpos configurable, and used this on tricorder, alpr, ASH405, T4160QDS, and T4240QDS (these boards failed to build for me without doing so, due to a size increase). On tricorder SPL, this saves 2576 bytes (and makes the SPL build again) versus the new default of 640 eccpos and 32 oobfree, and saves 336 bytes versus the old default of 128 eccpos and 8 oobfree.

cfi_flash: Add prototypes of overridable functions

2013-07-30T07:11:54Z

This commit adds some prototypes into include/mtd/cfi_flash.h. These functions are defined with a weak attribute in drivers/mtd/cfi_flash.c. This means they can be overrided by board-specific ones if necessary. When defining such functions under board/ directory or somewhere, cfi_flash.h should be included. This makes sure that board-specfic cfi functions are defined in a correct prototype. Signed-off-by: Masahiro Yamada Signed-off-by: Stefan Roese
