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 Due to this subsequent parsing of sf entities will fail, as string pointed by devstr is no longer valid sf dev arguments.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.

2014-10-22dm: Add spi.h header to a few filesSimon Glass
Some files are using SPI functions but not explitly including the SPI header file. Fix this, since driver model needs it. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Jagannadha Sutradharudu Teki <jagannadh.teki@gmail.com>
