- * 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).

- * is 0, the base address is 0x00000000. If MSR[IP] is 1, the base address

- * Other bits in the HRCW set up the Base Address and Port Size in BR0.

- * 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

- * 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).
