Paul Mackerras 413907e4bc soc: Move timebase back into the core and enable writing to it ... Instead of a single global timebase register in the SoC, we now have a timebase counter in each core; however, now they are only reset by the soc reset, not the core reset. Thus they stay in sync even when some cores are disabled (via the syscon cpu_ctrl register). This implements mtspr to the TBLW and TBUW SPRs, which write the lower and upper 32 bits of this core's timebase, respectively. In order to fulfil the ISA's requirements that (a) some method for getting the timebases into sync and (b) some method for preventing userspace from reading the timebase be provided by the platform, this adds a syscon register TB_CTRL with two read/write bits implemented; bit 0 freezes all the timebases in the system when set, and bit 1 makes reading the timebase privileged (in all cores).
