 * The last two definitions are for register offset compatibility.
 * These will be used with FRU_REG_INDEX macros, for P1.0 and P1.5, so 1.5
 * register offsets in upper nibble of fru_offset[] tables will be consistent.
 * This happens because the HLTHY INTs and INT masks come before the slots and
 * FRUs.  That's what changes the register offsets.
 * The only EXCEPTION is the ALARM RESET register, which for P1.5 is not
 * BASE + 3 as in all other cases, but BASE + 1.  FRU_REG_INDEX(code,base) does
 * NOT work for ALARM RESET.  Use ALARM_RESET_REG_INDEX() instead.
 * FRU_REG_INDEX() works differently for P1.0, using offset groups to calculate
 * the index to the fru_offset[] table.

 * REGISTER BIT OFFSETS
 * For the bit definitions, the SCB register sets are divided into two tables,
 * 1. scb_1x_fru_offset[]	bit-offsets for all FRUs and
 *				Interrupt events
 * 2. scb_1x_sys_offset[]	for system command/control registers
 *				and any remaining bits, like MPID.
 *
 * This is a bit historic from P0.6,P1.0 days.
 * The fru_offset table is indexed using the SCTRL_EVENT_ codes defined in
 * mct_topology.h.  Almost all of these describe interrupt generated events.
 * Ths sys_offset table contains anything else, mostly the System Control
 * registers and some bit definitions form the config/status registers.
