The size of the scatter-gather map table is determined by the size of the PCI
target window as defined by the PCI mask register (see Table 5–8). Because the
scatter-gather map is located in system memory, bit sysBus<33> is always zero.
Bits sysBus<32:2> are obtained from the translated base register and the PCI
address.
