# To add a new board (that uses an I.MX System On a Chip) you need:
# - The package name. Example: uboot4extlinux-tbs2910
# - The u-boot configuration. Example: tbs2910_defconfig
# - The name of the board(s). Example: TBS2910 Matrix ARM mini PC
#   A single package / u-boot configuration sometimes support multiple
#   boards and the configuration name doesn't always have the boards names
#   in it. Example: uboot4extlinux-am335x_bone supports various BeagleBones,
#   the AM335x GP EVM and the EVM SK all in one u-boot binary and package.
# - If relevant, the packages it replaces, if there are older u-boot packages
#   also supporting that board. Example:uboot-a20-olinuxino-micro
#
# Ideally we'd like to enable people to only add these 4 variables in this
# package to add a new board. These 4 variables could go in something like
# a CVS file that is parsed, but that would require to be able to dynamically
# define packages, but even if eval package_{$_pkgname}() { [...] } works,
# it doesn't make that package function visible to makepkg.
#
# Because of that, contributors wanting to add new boards will have to search
# for example of the information mentioned above and add it in the PKGBUILD
# for their boards.
#
# After adding a new board in this PKGBUILD, to get the board officially
# supported by Parabola.you also need to create a page for it in the
# Parabola wiki for that board and update the ARM installation guide to
# point to it when relevant. Examples of that are available for other
# boards in the ARM installation guide.

# TODO:
# - Add the following boards
#   - 'mx6cuboxi'
#   - 'nitrogen6q'
#   - 'udoo'
#   - 'usbarmory'
#   - 'wandboard'
