* Decode a named region within a memory bank of a given type.
*
* This function handles selection of a memory region. The region is
* specified as an offset/size within a particular type of memory.
*
* The properties used are:
*
* <mem_type>-memory<suffix> for the name of the memory bank
* <mem_type>-offset<suffix> for the offset in that bank
*
* The property value must have an offset and a size. The function checks
* that the region is entirely within the memory bank.5

* @param mem_type Type of memory to use, which is a name, such as

* @param suffix String to append to the memory/offset

* @param basep Returns base of region
* @param sizep Returns size of region
* @return 0 if OK, -ive on error
