=> R0 = flags: bit 4 => bufferable
bit 5 => cacheable
bits 6-8 => policy (see OS_DynamicArea)
bit 30 => IO else Memory
R1 = PCI address
R2 = length
<= R4 = logical address
This call maps in the given PCI address (found with PCI_HardwareAddress) into the logical memory map subject to the flags in bits 4 to 8 of R0.
If bit 30 is set it will be marked as IO, else marked as Memory.
