This patch introduces a new env var which specifies which device is the rootfs device to be used in Linux, passed to Linux via bootargs, identified by the rootfs partition's PARTUUID. global.bootm.root_dev supplements global.bootm.appendroot, in that it overrides appendroot's naïve default, which picks the partition that the kernel resides on (global.bootm.image). Example: detect mmc2 global.bootm.image='/mnt/mmc2.0/zImage' global.bootm.appendroot=1 global.bootm.root_dev=/dev/mmc2.1 boot mmc For proper patch, I would squash all commits. Changes from v1: - renamed env var s/root/root_dev/ - used filesystem-agnostic approach (root_dev now takes a /dev/ instead of a mounted partition) Robert Karszniewicz (3): bootm: add env var root_dev globalvar: add bootm.root_dev bootm: handle global.bootm.root_dev common/bootm.c | 18 ++++++++++++++++-- include/bootm.h | 2 ++ 2 files changed, 18 insertions(+), 2 deletions(-) -- 2.7.4 _______________________________________________ barebox mailing list barebox@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/barebox
