After converting to multiplatform the old IXP4xx defconfig doesn't even activate the ethernet driver anymore, we need to refresh this thoroughly. - Drop options that ARCH_MULTI_V5 selects for us. - Some options moved around because of multiplatform and because generic Kconfig movements. - Explicitly deselect ARCH_MULTI_V7 so ARCH_MULTI_V5 becomes available and we can select ARCH_IXP4XX - Drop all MACH_* that do not exist anymore. - Compress the kernel and initramfs with XZ as the memory is often limited for these machines. - Make sure IXP4XX_QMGR and IXP4XX_NPE is selected. - Make sure the MTD_PHYSMAP_IXP4XX is selected and not the old MTD_IXP4XX (will be deleted). - Activate CRYPTO_DEV_IXP4XX - Add some very basic default drivers such as AT24 EEPROMs used in many routers. - Add some kernel configs needed to bring up OpenWrt which is the only userspace for these devices: CGROUPS, DEVTMPFS, INOTIFY_USER, SIGNALFD, TIMERFD, EPOLL, OVERLAY_FS and SQUASHFS.
