14  * PEC XSCOM registers
15  *
16  * There a 3 PECs in P9. Each PEC can have several PHBs. Each PEC has some
17  * "global" registers and some "per-stack" (per-PHB) registers. Those are
18  * organized in two XSCOM ranges, the "Nest" range and the "PCI" range, each
19  * range contains both some "PEC" registers and some "per-stack" registers.
20  *
21  * Finally the PCI range also contains an additional range per stack that
22  * passes through to some of the PHB own registers.
23  *
24  * PEC0 can contain 1 PHB  (PHB0)
25  * PEC1 can contain 2 PHBs (PHB1 and PHB2)
26  * PEC2 can contain 3 PHBs (PHB3, PHB4 and PHB5)

30  * This is the "stack" offset, it's the offset from a given range base

32  * stacks, thus for PEC2, the global registers are at offset 0, the
33  * PHB3 registers at offset 0x40, the PHB4 at offset 0x80 etc....
34  *
35  * It is *also* the offset to the pass-through SCOM region but in this case
36  * it is 0 based, ie PHB3 is at 0x100 PHB4 is a 0x140 etc..
