Hi, this series allows Barebox to be entered in HYP mode. As the HYP mode is a whole different world it just makes sure to install the hooks needed to get back into HYP and then switches to SVC mode as fast as it can. The kernel is then started in HYP mode by default. This is needed in order to get RasPi 3 support in place, where the firmware opts to hand us the CPUs in HYP mode. I've tested this series on another ARMv7 board, to make sure I didn't break something obvious, but I would still welcome some eyeballs on this code, as it touches a good deal of the lowlevel code.
