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) Signed-off-by: Viacheslav Mitrofanov <v.v.mitrofa...@yadro.com> --- Changes in v2: - Split big patches into smaller - If an address in tftpboot is IPv6 than use IPv6 to boot - Add tests Viacheslav Mitrofanov (17): net: ipv6: Add IPv6 basic primitives net: ipv6: Add IPv6 build options net: ipv6: Add callbacks declarations to get access to IPv6 variables net: ipv6: Add Neighbor Discovery Protocol (NDP) net: ipv6: Add string_to_ip6 converter net: ipv6: Enable IPv6 typeconversion specifier net: ipv6: Add ip6addr, gatewayip6, serverip6 variables callbacks net: ipv6: Add implementation of main IPv6 functions net: ipv6: Incorporate IPv6 support into u-boot net subsystem net: tftp: Add IPv6 support for tftpboot net: ping6: Add ping6 command test: dm: eth: Add string_to_ip6 test test: dm: eth: Add csum_ipv6_magic test test: dm: eth: Add ip6_addr_in_subnet test test: dm: eth: Add ip6_make_snma test test: dm: eth: Add ip6_make_lladdr test test/py: add a ping6 test cmd/Kconfig | 7 + cmd/net.c | 48 ++++ include/env_callback.h | 10 + include/env_flags.h | 10 + include/ndisc.h | 65 +++++ include/net.h | 4 +- include/net6.h | 312 ++++++++++++++++++++++++ lib/net_utils.c | 122 ++++++++++ lib/vsprintf.c | 11 +- net/Kconfig | 4 + net/Makefile | 3 + net/ndisc.c | 276 ++++++++++++++++++++++ net/net.c | 70 +++++- net/net6.c | 484 ++++++++++++++++++++++++++++++++++++++ net/ping6.c | 117 +++++++++ net/tftp.c | 62 ++++- test/dm/eth.c | 140 +++++++++++ test/py/tests/test_net.py | 15 ++ 18 files changed, 1741 insertions(+), 19 deletions(-) create mode 100644 include/ndisc.h create mode 100644 include/net6.h create mode 100644 net/ndisc.c create mode 100644 net/net6.c create mode 100644 net/ping6.c -- 2.25.1
