This patch set adds basic IPv6 support to U-boot. It is based on Chris's Packham patches (https://lists.denx.de/pipermail/u-boot/2017-January/279366.html) Chris's patches were taken as base. There were efforts to launch it on HiFive SiFive Unmatched board but the board didn't work well. The code was refactored, fixed some bugs as CRC for little-endian, some parts were implemented in our own way, something was taken from Linux. Finally we did manual tests and the board worked well.
Testing was done on HiFive SiFive Unmatched board (RISC-V)

--- Changes in v2: - Split big patches into smaller - If an address in tftpboot is IPv6 than use IPv6 to boot - Add tests
Changes in v3: - Added functions and structures description in whole patch-series - Removed memory allocation in on_ip6addr() - Some functions got return code from errno.h - Add to string_to_ip6() length parameter to avoid obligatory null termination - Add a lot of small decorative cnages
Changes in v4: - Fixed funcs and structures style description - Added omitted tags
Changes in v5: - Move patches to the latest u-boot version - Move IPV6 tests under CONFIG_IPV6 ifdef - Add CONFIG_IPV6 to sandboxes
