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

/*
 * This is the "stack" offset, it's the offset from a given range base
 * to the first "per-stack" registers and also the stride between
 * stacks, thus for PEC2, the global registers are at offset 0, the
 * PHB3 registers at offset 0x40, the PHB4 at offset 0x80 etc....
 *
 * It is *also* the offset to the pass-through SCOM region but in this case
 * it is 0 based, ie PHB3 is at 0x100 PHB4 is a 0x140 etc..
