Hi!
Could someone take a look at these lines from fixup_bigphys_addr():
// in au1000.h
#define Au1500_PCI_MEM_START 0x440000000ULL
#define Au1500_PCI_MEM_END 0x44FFFFFFFULL
// in setup.c
start = (u32)Au1500_PCI_MEM_START;
end = (u32)Au1500_PCI_MEM_END;
/* check for pci memory window */
if ((phys_addr >= start) && ((phys_addr + size) < end)) {
return (phys_addr - start) + Au1500_PCI_MEM_START;
}
For the (unlikely?) case that I want to use a size of 0x0 1000 0000,
'phys_addr+size == end+1'. IOW I need 'phys_addr+size-1' to get the last
address and use '<= end' to compare with the last valid address in the range.
Right?
Uli
