Shouldn't we be modelling the PMU then?
Power Management Unit (PMU) is quite tricky and not critical for emulation.
At this time PMU emulation is paused. It just represents about 16K
registers array.
I don't think that it is a good idea to include such a device into
mainline code in
order to provide one of it's register for secondary CPU boot-up.
+ memory_region_init_ram(&s->bootreg_mem, NULL, "exynos4210.bootreg", 0x4);
+ memory_region_add_subregion(system_mem, EXYNOS4210_SECOND_CPU_BOOTREG,
+&s->bootreg_mem);

+static int exynos4_board_smp_bootreg_addr[EXYNOS4_NUM_OF_BOARDS] = {
+ [EXYNOS4_BOARD_NURI] = EXYNOS4210_SECOND_CPU_BOOTREG,
+ [EXYNOS4_BOARD_SMDKC210] = EXYNOS4210_SECOND_CPU_BOOTREG,
+};
Is this actually likely to differ between boards, or is it really a property
of the SoC itself?
Yes, it is specific to a board. There are different boards on exynos4210
SOC which have
different bootreg addresses. At this time we don't emulate them.
