For one at least pci_mem_start has to be precisely 32 bits wide, so use uint32_t for both. Otherwise expressions like "pci_mem_start <<= 1" won't have the intended effect (in their context). Further since its introduction pci_mem_end was never written to. Mark it const to make this explicit. Finally drop PCI_MEM_END: It is used just once and needlessly disconnected from the other constant (RESERVED_MEMBASE) it needs to match. Use RESERVED_MEMBASE as initializer of pci_mem_end instead.
