* phytec-som-imx6: ksz8081_phy_fixup: Don't override B-CAST_OFF strap-inJan Remmet2018-12-051-1/+10
| | | | | | | | | | | | As PHY address 0 is not used on PHYTEC i.MX 6 and i.MX 6UL SOMs we do not have to override the B-CAST_OFF strap-in which disables broadcast on PHY address 0. Also add some comments about the magic values.

| * | ARM: install HYP vectors at PBL and Barebox entryLucas Stach2018-11-054-0/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the CPU was already in HYP mode when entering the PBL, install a simple trap handler to allow to get back from SVC to HYP before switching to HYP mode. As the vectors are part of the currently running binary, we need to do the same setup when starting the real Barebox binary, as the PBL setup vectors might get overwritten. To do this we trap into HYP mode just before jumping to Barebox and then re-do the vector setup and SVC switch as the first thing in Barebox proper.
