From: Adam Duskett Date: Mon, 15 Mar 2021 17:31:06 +0000 (-0700) Subject: package/mender: do not automatically select uboot tools if uboot is selected X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=136f317c68e98882d1c146baa1804395a992d548;p=buildroot.git package/mender: do not automatically select uboot tools if uboot is selected Because uboot requires a set of unique patches for each board, the upstream package developers are phasing out supporting uboot wherever possible. Instead, they recommend using Grub2 as a secondary bootloader and using the mender-grubenv package. Because the mender-grubenv file provides it's own fw_printenv script, it is not possible to know if U-Boot's fw_printenv or mender-grubenv's fw_printenv should be used. As such, remove selecting uboot tools when uboot is selected, and instead add a more comprehensive note in the help section about what Mender requires for uboot and grub2-based systems, with a link to the meta-mender github project for the base uboot patches, and a link to the official documentation on manual uboot integration.
