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>
2017-07-28dfu: remove limitation on partition sizePatrick Delaunay
Change long (32 bits on arm) to u64 (same type than offset) for size and read offset r_left So partition and device used for DFU can be greater than 4GB Signed-off-by: Patrick Delaunay <patrick.delaunay@st.com>
2017-07-28dfu: allow dfu read on partition greater than 2GBPatrick Delaunay
solve issue on get_medium_size() function the detection of error is a simple test < 0 but for ARM platform, long is 32bits and 2GB = 0x80000000 is seen as error. I solve the issue by changing the prototype fo the function to separate size and result. This patch prepare the next patch with size change to u64.

2015-11-03dfu: dfu_sf: Pass duplicate devstr to parse_devVignesh R
parse_dev() alters the string pointed by devstr parameter. Due to this subsequent parsing of sf entities will fail, as string pointed by devstr is no longer valid sf dev arguments. Fix this by passing pointer to the copy of the string to parse_dev instead of pointer to the actual devstr. Signed-off-by: Vignesh R <vigneshr@ti.com> Reviewed-by: Tom Rini <trini@konsulko.com>
2015-10-19dfu: dfu_sf: Take the start address into accountFabio Estevam
The dfu_alt_info_spl variable allows passing a starting point for the binary to be flashed in the SPI NOR. For example, if we have 'dfu_alt_info_spl=spl raw 0x400', this means that we want to flash the binary starting at address 0x400. In order to do so we need to erase the entire sector and write to the the subsequent SPI NOR sectors taking such start address into account for the address calculations. Tested by succesfully writing SPL binary into 0x400 offset and the u-boot.img at offset 64 kiB of a SPL NOR.

2015-10-19dfu: dfu_sf: Use the erase sector size for erase operationsFabio Estevam
SPI NOR flashes need to erase the entire sector size and we cannot pass any arbitrary length for the erase operation. To illustrate the problem: Copying data from PC to DFU device Download [=========================] 100% 478208 bytes Download done. state(7) = dfuMANIFEST, status(0) = No error condition is present state(10) = dfuERROR, status(14) = Something went wrong, but the device does not know what it was Done! In this case, the binary has 478208 bytes and the M25P32 SPI NOR has an erase sector of 64kB. 478208 = 7 entire sectors of 64kiB + 19456 bytes. Erasing the first seven 64 kB sectors works fine, but when trying to erase the remainding 19456 causes problem and the board hangs. Fix the issue by always erasing with the erase sector size.
