[coreboot] x60 and macbook21 builds fail

[Mono]

is it just me? trying to build coreboot for a X60 motherboard or a macbook21 fails with tons of the following error:

src/northbridge/intel/i945/gma.c: In function 'gtt_setup':
src/northbridge/intel/i945/gma.c:72:10: error: passing argument 1 of 'write32' makes pointer from integer without a cast [-Werror]
  write32(mmiobase + GFX_FLSH_CNTL, 0);
          ^

 static inline __attribute__((always_inline)) void write32(volatile void *addr, uint32_t value)
                                                   ^

  write32(mmiobase + PGETBL_CTL, PGETBL_save);

I figured this error occurs since commit bde6d309 (x86: Change MMIO addr in readN(addr)/writeN(addr, val) to pointer). I don't know how to fix it though or did I configured any wrong? Any help is much appreciated.
