The final pieces of IXP4xx board files were deleted in Linux v5.19. Ext4 root filesystems on CF and USB are supported by the default config. We support these three initial targets: - The Gateworks Avila GW2348 reference design has 64MB of RAM and 32MB of flash and also supports USB and CompactFlash. - The Gateworks Cambria GW2358 reference design has 128MB of RAM and 32MB of flash and also supports USB and CompactFlash. - The old and stable Linksys NSLU2 works fine as well, albeit it only has 32MB of RAM so it has been marked as non-default. The 8MB of flash can only fit the kernel, so it has been patched to boot from exteral media on USB. I have used it successfully as a NAS with ksmbd and LUCI web API, see: https://dflund.se/~triad/krad/ixp4xx/ Signed-off-by: Linus Walleij --- package/firmware/ixp4xx-microcode/Makefile | 59 +++++
