+ *  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).

+(C) 2003 Arun Dharankar <ADharankar@ATTBI.Com>
+
+Attached is an IDMA example code for MPC8260/PPCBoot. I had tried to
+search around and could not find any for implementing IDMA, so
+implemented one. Its not coded in the best way, but works.
+
+Also, I was able to test the IDMA specific code under Linux also
+(with modifications). My requirement was to implement it for
+CompactFlash implemented in memory mode, and it works for it under
+PPCBoot and Linux.
