The sysctl PDCM_PD_*_SENSE registers control various power domains in
the system and allow the guest to configure which conditions keep a
power domain awake and what power state to use when the domain is in
a low power state. QEMU doesn't model power domains, so for us these
registers are dummy reads-as-written implementations.
The SSE-300 has a different power domain setup, so the set of
registers is slightly different:
Offset SSE-200 SSE-300
---------------------------------------------------
0x200 PDCM_PD_SYS_SENSE PDCM_PD_SYS_SENSE
0x204 reserved PDCM_PD_CPU0_SENSE
0x208 reserved reserved
0x20c PDCM_PD_SRAM0_SENSE reserved
0x210 PDCM_PD_SRAM1_SENSE reserved
0x214 PDCM_PD_SRAM2_SENSE PDCM_PD_VMR0_SENSE
0x218 PDCM_PD_SRAM3_SENSE PDCM_PD_VMR1_SENSE
Offsets 0x200 and 0x208 are the same for both, so handled in a
previous commit; here we deal with 0x204, 0x20c, 0x210, 0x214, 0x218.
(We can safely add new lines to the SSE300 vmstate because no board
uses this device in an SSE300 yet.)
