SPDX: Convert all of our single license tags to Linux Kernel style 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> 2018-05-06 21:58:06 +00:00			`# SPDX-License-Identifier: GPL-2.0+`
SPI Flash subsystem This adds a new SPI flash subsystem. Currently, only AT45 DataFlash in non-power-of-two mode is supported, but some preliminary support for other flash types is in place as well. Signed-off-by: Haavard Skinnemoen <haavard.skinnemoen@atmel.com> 2008-05-16 09:10:33 +00:00			`#`

dm: sf: Add a uclass for SPI flash Add a driver model uclass for SPI flash which supports the common operations (read, write, erase). Since we must keep support for the non-dm interface, some modification of the spi_flash header is required. CONFIG_DM_SPI_FLASH is used to enable driver model for SPI flash.

sf: Rename sf_params.c to spi_flash_ids.c Now the flash params table as renamed to spi_flash_ids structure, so rename the sf_params.c to spi_flash_ids.c and remove the legacy.

Note (From Jagan): For testing raw mtd parition erase/read/write operations using cmd_sf, sf_mtd should be required to register the spi flash device to MTD layer but the sf_mtd_info ops were not required until and unless if we use any flash filesystem layer say for example UBI. Due to this the foot-print got increased ~290bytes in non-UBI case here that should be acceptible.

sandbox: spi: Add new SPI flash driver This adds a SPI flash driver which simulates SPI flash clients. Currently supports the bare min that U-Boot requires: you can probe, read, erase, and write. Should be easy to extend to make it behave more exactly like a real SPI flash, but this is good enough to merge now. sjg@chromium.org added a README and tidied up code a little. Added a required map_sysmem() for sandbox.
