+ *  Hard Reset Configuration Word (HRCW) table
+ *
+ *  The Hard Reset Configuration Word (HRCW) sets a number of useful things
+ *  such as whether there is an external memory controller, whether the
+ *  PowerPC core is disabled (i.e. only the communications processor is
+ *  active, accessed by another CPU on the bus), whether using external
+ *  arbitration, external bus mode, boot port size, core initial prefix,
+ *  internal space base, boot memory space, etc.
+ *
+ *  These things dictate where the processor begins execution, where the
+ *  boot ROM appears in memory, the memory controller setup when access
+ *  boot ROM, etc. The HRCW is *extremely* important.
+ *
+ *  The HRCW is read from the bus during reset. One CPU on the bus will
+ *  be a hard reset configuration master, any others will be hard reset
+ *  configuration slaves. The master reads eight HRCWs from flash during
+ *  reset - the first it uses for itself, the other 7 it communicates to
+ *  up to 7 configuration slaves by some complicated mechanism, which is
+ *  not really important here.
+ *
+ *  The configuration master performs 32 successive reads starting at address
+ *  0 and incrementing by 8 each read (i.e. on 64 bit boundaries) but only 8
+ *  bits is read, and always from byte lane D[0-7] (so that port size of the
+ *  boot device does not matter). The first four reads form the 32 bit HRCW
+ *  for the master itself. The second four reads form the HRCW for the first
+ *  slave, and so on, up to seven slaves. The 32 bit HRCW is formed by
+ *  concatenating the four bytes, with the first read placed in byte 0 (the
+ *  most significant byte), and so on with the fourth read placed in byte 3
+ *  (the least significant byte).

+ *  vector at offset 0x100 relative to the base set by MSR[IP]. If MSR[IP]
+ *  is 0, the base address is 0x00000000. If MSR[IP] is 1, the base address
+ *  is 0xfff00000. In the case of a Power On Reset or Hard Reset, the value
+ *  of MSR[IP] is determined by the CIP field in the HRCW.
+ *
+ *  Other bits in the HRCW set up the Base Address and Port Size in BR0.
+ *  This determines the location of the boot ROM (flash or EPROM) in the
+ *  processor's address space at boot time. As long as the HRCW is set up
+ *  so that we eventually end up executing the code below when the processor
+ *  executes the reset exception, the actual values used should not matter.
+ *
+ *  Once we have got here, the address mask in OR0 is cleared so that the
+ *  bottom 32K of the boot ROM is effectively repeated all throughout the
+ *  processor's address space, after which we can jump to the absolute
+ *  address at which the boot ROM was linked at compile time, and proceed
+ *  to initialise the memory controller without worrying if the rug will be
+ *  pulled out from under us, so to speak (it will be fine as long as we
+ *  configure BR0 with the same boot ROM link address).
