They used to be in beaglebone and rpi at least, but the beaglebone stuff appears to currently be in a state of flux. The rpi port still has the patches, though. The patches aren't rpi-specific, I've been using them on all arm u-boot stuff (I have uncommited changes for wandboard and other imx6 systems, and we use this stuff at $work too). https://svnweb.freebsd.org/ports/head/sysutils/u-boot-rpi/files/patch-common_cmd__elf.c?view=co https://svnweb.freebsd.org/ports/head/sysutils/u-boot-rpi/files/patch-common_cmd__boot.c?view=co The last version of u-boot I know for sure those two patches apply cleanly to was 2016.01; I haven't looked at any u-boot releases since then. -- Ian
