This is not the right\nway to work with git.\n\nThe git way is to add\nhttps://git.kernel.org/pub/scm/utils/dtc/dtc.git\nas git submodule (https://git-scm.com/docs/git-submodule).\n\nIn our make file we can then use git submodule init, git submodule\nupdate, git verify-tag before we build a dtc with the appropriate version.\n\nThis way we can build dtc from sources but stay in sync with the upstream.\n\nRegards\n\nHeinrich","headers":{"Return-Path":"","X-Original-To":"incoming@patchwork.ozlabs.org","Delivered-To":"patchwork-incoming@bilbo.ozlabs.org","Authentication-Results":"ozlabs.org;\n\tspf=none (mailfrom) smtp.mailfrom=lists.denx.de\n\t(client-ip=81.169.180.215;

Whoever wants to use DTO,\nshould have new enough DTC and I'm fine with the build failing if they\ndon't.\n\nThis heavy-handed approach of imposing custom DTC build on everyone\nbecause of a feature noone uses is awful and I disagree with it.

The timing for dtc 1.4.3 just wasn't good for\nDebian stable; not through any fault of the maintainers.\n\n\nFor what it's worth, I've submitted some updated packaging to the\ndevice-tree-compiler (a.k.a. dtc) maintainers in Debian, including\nupdating the version. Hopefully that will get uploaded one way or\nanother soon.\n\nGiven that Debian in general prefers not to embed code copies, with\nu-boot, I'm hoping it will be fairly straightforward to use an external\ndtc, once the newer dtc version is available in Debian?\n\n\nlive well,\n vagrant","headers":{"Return-Path":"","X-Original-To":"incoming@patchwork.ozlabs.org","Delivered-To":"patchwork-incoming@bilbo.ozlabs.org","Authentication-Results":"ozlabs.org;\n\tspf=none (mailfrom) smtp.mailfrom=lists.denx.de\n\t(client-ip=81.169.180.215;
