Update to next U-Boot timed release. Remove now obsolete patch 100-01-board-mediatek-add-more-network-configurations.patch Default IP addresses are now dealt with in Kconfig, no longer in board- specific C header files. Add patches to restore ANSI support in bootmenu which was broken upstream, always use high-speed mode on serial UART for improved stability and fix an issue with pinconf not being applied on MT7623 resulting in eMMC being inaccessible when booting from micro SD card. In order to keep the size of the bootloader on MT7623 below 512kB remove some unneeded commands on both MT7623 boards. Tested on: * BananaPi BPi-R2 (MT7623N) * BananaPi BPi-R3 (MT7986A) * BananaPi BPi-R64 (MT7622A) * Linksys E8450 (MT7622B) Signed-off-by: Daniel Golle <daniel@makrotopia.org>
