I don't have a lot of control over the bootloaders on MSM. We can probably move away from ATAGS, but only after every kernel that could possibly boot on that target will work with DT. I don't see that happening for at least a year. David -- Sent by an employee of the Qualcomm Innovation Center, Inc. The Qualcomm Innovation Center, Inc. is a member of the Code Aurora Forum.
