- drop support for PP500x: it's very different from other PP and although it would be possible to support them, I don't have one to test the code - make sure only the CPU is started - add PP descriptor to report chip ID and revision - add code in shell and lua to support pp (no register description yet) - compile for ARMv4 because PP502x is an ARM7TDMI Change-Id: I36c4e465dfc2cfdfe7433b2f65cc8f6f0720fe62
