# To add a new board (that uses an Allwinner System On a Chip) you need:
# - The package name. Example: uboot4extlinux-a20-olinuxino_micro
# - The u-boot configuration. Example: A20-OLinuXino_MICRO_defconfig
# - The name of the board(s). Example: A20 OLinuXino Micro
#   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.

# We have a ${pkgver}-${pkgrel} that looks like that:
# '2021.07-r1.parabola3' and all the individual components are needed:
# - '2021.07' corresponds to the upstream u-boot version. It is needed
#   to know which u-boot version source code is used.
# - 'r1' corresponds to the u-boot-libre revision. Without it it would
#   be impossible to fix bugs inside the u-boot-libre deblob script.
# - .parabola3 is the Parabola package revision. Without it it would be
#   impossible to fix bugs inside this PKGBUILD.
# As for the '-r1', it cannot go inside pkgver, else we end up with an
# error like that when running makepkg:
# ==> ERROR: pkgver is not allowed to contain colons, forward slashes,
#     hyphens or whitespace.
# so it was moved in pkgrel.
