This is the latest release tag in the Xilinx repository, based on
U-Boot v2016.01 in the mainline.
Commit 46d6a561be ("zedboard: Generate BOOT.BIN automatically")
switched from the Xilinx GitHub repository to the U-Boot mainline,
but this commit gets it back to the Xilinx GitHub repository for the
following reasons:
- This defconfig still relies on the Xilinx's local repository for
the kernel. The vendor does the best test for the combination of
U-Boot and the kernel with the same release tag (xilinx-v2016.2
in this case).
- At the time of commit 46d6a561be, the u-boot-xlnx still needed
manual copy of ps7_init(_gpl).c/h in order to build a working SPL
image. So, the mainline U-Boot had advantage in that point of
time. However, the improvement in the mainline U-Boot was merged
into the u-boot-xlnx at the xilinx-v2015.3 release. Now, the
mainline and the u-boot-xlnx are even in this point of view.
- The mainline U-Boot defaults to boot FIT, so something must be
done; either patch environments around with a local patch to
switch to uImage booting (current solution), or build an FIT
with a post build script (chromebook snow does this). On the
other hand, the Xilinx repository defaults to uImage booting,
so it is straightforward, and needs no addition care.
This commit does:
- Switch to the Xilinx custom git repository, and stick to the
xilinx-v2016.2 tag.
- Delete the local patch board/avnet/zedboard/uboot/0001...
since the Xilinx custom repository can boot uImage by default.
- Enable BR2_TARGET_UBOOT_FORMAT_IMG instead of ..._FORMAT_DTB_IMG
since all the Zynq boards in U-Boot enable CONFIG_OF_EMBED.
- Replace BR2_TARGET_UBOOT_ZYNQ_IMAGE with BR2_TARGET_UBOOT_SPL_NAME
since U-Boot can natively generate the Zynq boot image now. The
Zynq image support for mkimage tool was upstreamed at v2016.01
(so xilinx-v2016.1 as well), so no additional tool is needed
any more.
