Currently list of supported SoC is as follows: - i.MX6 (tested on i.MX6Q) - i.MX7 (tested on i.MX7D) - VFxxx (tested on VF610) Changes since [v1]: - i.MX reset reason detection code was converted to do detect the source with bitmasking as opposed to having a switch statement, due to potential problems with the latter as was pointed out by Philipp in [thread1] - Change above also allowed to unify VFxxx and i.MX codepaths without the need to introduce a dedicated VFxxx centric function [v1] http://lists.infradead.org/pipermail/barebox/2018-April/032614.html [thread1] http://lists.infradead.org/pipermail/barebox/2018-April/032708.html Feedback is wellcome!
