X-BeenThere: u-boot@lists.denx.de X-Mailman-Version: 2.1.18 Precedence: list List-Id: U-Boot discussion List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , MIME-Version: 1.0 Errors-To: u-boot-bounces@lists.denx.de Sender: "U-Boot" Hi Most featureful boards, such as the Cubietruck, have been broken since the release 2017.09 (the two variants of the Olinuxino-Lime2 and the cubietruck at least, possibly more since then). This is due to a size increase of the binary that will trip us across the size we've been using in our default configuration since forever, and widely distributed through the u-boot-sunxi-with-spl.bin file. We would have several ways to work around it. The first one would be to just increase the offset of the environment. However, since it would break all the environments of our users and possibly the custom partition scheme that they would have created, it doesn't really seem like a smart move. The second one would be to move the environment to a filesystem file, which would also break all the existing users. This can be envisionned as a long term fix though. Another one would be to start trimming down a bit our enabled options in order to reduce the size and to gain some extra space for users customisations. However, this will always result in pointless and endless discussions, so let's move away from that. The final one that has been implemented would be to just build U-Boot using thumb2 to push back the issue until hopefully I'm no longer maintainer or the switch to the env filesystem would have been done. I've also added a patch to make sure that the compilation breaks and that we can notice.
