/*
 * Memory functions.  64-bit and 32-bit accesses are done through
 * dense memory space, everything else through sparse space.
 * 
 * For reading and writing 8 and 16 bit quantities we need to 
 * go through one of the three sparse address mapping regions
 * and use the HAE_MEM CSR to provide some bits of the address.
 * The following few routines use only sparse address region 1
 * which gives 1Gbyte of accessible space which relates exactly
 * to the amount of PCI memory mapping *into* system address space.
 * See p 6-17 of the specification but it looks something like this:
 *
 * 21164 Address:
 * 
 *          3         2         1                                                               
 * 9876543210987654321098765432109876543210
 * 1ZZZZ0.PCI.QW.Address............BBLL                 
 *
 * ZZ = SBZ
 * BB = Byte offset
 * LL = Transfer length
 *
 * PCI Address:
 *
 * 3         2         1
