move WIP u-boot modifications in libre-testing
I asked bill-auger to push his modifications so he uploaded the packages to libre-testing and the PKGBUILD modifications to abslibre. Since the pakcages have been uploaded to libre-testing it's better to move them here. While the code is not ready yet, it enables users to test the new u-boot which fixes the Ethernet PHY. From linux-sunxi we have[1]: Proper fix for rev. F and newer is to apply trace length compensation at the PHY. This is done by default (also for rev. H and newer despite commit message mentioning only realtek not Micrel) since mainline linux v5.15 and since mainline u-boot v2022.04; [1]https://linux-sunxi.org/Olimex_A20-OLinuXino-Lime2#calibrate_at_PHY That page also has more background on the issue being fixed here (basically making all the various Lime 2 A20 revisions (which have different Ethernet PHY) work with the same u-boot binary / package.

+Date: Sat, 29 May 2021 19:14:22 +0200
+Subject: [PATCH] Add tool to dump sunxi images
+
+ $./tools/dumpimage -l ~/work/temp/lime1.img
+ Allwinner eGON image, size: 24576 bytes
+ SPL header version 0.2
+ DT name: sun7i-a20-olinuxino-lime2-emmc
+ $ ./tools/dumpimage -l ~/work/temp/parabola.img
+ Allwinner eGON image, size: 24576 bytes
+ SPL header version 0.2
+ DT name: sun7i-a20-olinuxino-lime2-emmc
+
+TODO:
+- why do we have the lime2 dt detected above? is the
+ env a leftover from the previous image somehow?
+- Handle block devices:
+ $ sudo ./tools/dumpimage -l /dev/sdb
+ Image Type: MVEBU Boot from (null) Image
+ Image version:0
+ Data Size: -4 Bytes = 4194304.00 KiB = 4096.00 MiB
+ Load Address: 00000000
+ Entry Point: 00000000
+- Make it easily parsable by tools
+- Force type to sunxi_egon

+# 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 could add automatic updates. It would require a bit of
+ work:
+ - u-boot has code to detect images. We could write a tool that
+ reuses that code to detect Allwinner eGON images.
+ See the 0001-Add-tool-to-dump-sunxi-images.patch for inspiration
+ on how to do that.
+ - Once done that tool could then be leveraged for detecting
+ u-boot installations and updating the u-boot images with a
+ pacman hook for devices that are booted.
+ - We could also check the devicetree to make sure we are
+ running on the right device.
+ - For chroots we could somehow detect that we are in a chroot
+ and find if there is an underlying block device, and upgrade
+ u-boot there.
+ - In any case we need to be careful not to break other computers:
+ some x86 laptops have eMMC too, and most of the time theses
+ eMMC also contains the BIOS and/or UEFI, so we don't want to
+ erase that. We also don't want to erase the laptop filesytems
+ either.
+- We need to build some infrastructure for users to report working
+ boards and mention it here and on the wiki for adding official
+ support for boards. We could for instance do something as simple
+ as possible like open a new bug tracker specially for that and
+ just reference that in the wiki for instance.
+- We also need to make dtb fragment work in u-boot to support more
+ use cases and possibly also package popular dtb fragment for the
+ beaglebone black.
+- In addition we could then leverage that to build an image for
+ the beaglebone black (or other boards) for flashing Libreboot.
+ This way Libreboot would benefit from an FSDG compatible image
+ that is also maintained by an upstream distribution.
+- We could also look maing an u-boot package that has UEFI compatibility
+ and also bundle GRUB with it. This way we could simplify the installation
+ instructions by leverage users knowledge about GRUB and also potentially
+ investigate if we could leverage the UEFI standard for easily upgrading
+ that u-boot+UEFI+grub image.
