[OpenWrt-Devel] [PATCH 9/9] sunxi: sysupgrade: add support for pine64 lts spi flash

[Oskari Lemmela]

Add support for updating SPI flash device firmware.

U-boot has to be programmed to spi flash device /dev/mtd0
manually before switching from sdcard to SPI flash device.

Running sysupgrade with sysupgrade.bin will write firmware
partition and copy configuration files from sdcard.
