+* This function sets new base and size for one the memory banks
+* (CS0 - CS3). It is the programmer`s responsibility to make sure that
+* there are no conflicts with other memory spaces. When two memory spaces
+* overlap, the MVÂ’s behavior is not defined .If a bank needs to be closed,

+* DESCRIPTION:
+* In addition to the address decoding mechanism, the CPU has an address

+* window can be remaped to a desired address target according to the remap
+* value within the remap register. The address remapping is useful when a
+* CPU address range must be reallocated to a different location on the
+* PCI bus. Also, it enables CPU access to a PCI agent located above the
+* 4Gbyte space. On system boot, each of the PCI memory spaces is maped to
+* a defualt value (see CPU interface section in the MV spec for the
+* default values). The remap mechanism does not always produce the desired
+* address on the PCI bus because of the remap mechanism way of working
+* (to fully understand why, please see the 'Address Remapping' section in
+* the MV's spec). Therefor, this function sets a desired remap value to
+* one of the PCI memory windows and return the effective address that
+* should be used when exiting the PCI memory window. You should ALWAYS use
+* the returned value by this function when remapping a PCI window and
+* exiting it. If for example the base address of PCI0 memory 0 is
+* 0x90000000, the size is 0x03ffffff and the remap value is 0x11000000,
+* the function will return the value of 0x91000000 that MUST
+* be used to exit this memory window in order to achive the deisred
+* remapping.
