# To add a new board (that uses an Allwinner System On a Chip) you need:
#
#  1. The u-boot configuration name. Example: `A20-OLinuXino_MICRO_defconfig`
#
#     Remove the the `_defconfig` suffix and add this to the `_targets=()`
#     variable near the top of this PKGBUILD.
#
#  2. The name of the board(s). Example: `A20 OLinuXino Micro`.
#
#     This is usually very similar to the u-boot configuration name, but
#     sometimes a single u-boot configuration supports multiple boards and the
#     configuration name doesn't always denote all board names.  For example:
#     uboot4extlinux-am335x_bone supports various BeagleBones (the AM335x GP EVM
#     and the EVM SK).
#
#     Add a `package_uboot4extlinux-*()` function to the bottom of this
#     PKGBUILD, following the existing pattern.  The `*` in the function name
#     should be the above (1) configuration, but converted to all-lowercase.
#
#  3. (Optional) If relevant, the Parabola and/or Arch Linux ARM package names
#     that it replaces, if there are older u-boot packages also supporting that
#     board. Example: `uboot-a20-olinuxino-micro`
#
# After adding a new board in this PKGBUILD, you should also create a
# 'Computers/' page on the Parabola wiki for that board, and update the relevant
# sections of the 'ARM Installation Guide' to refer to it for any board-specific
# details:
