Speed up RayeR SPIPGM driver by a factor of 2
Allow specification of an alternate base address with flashrom -p rayer_spi:iobase=0x278 Any base address is allowed as long as it is nonzero, below 65536 and a multiple of four. Read speed is now on par with original spipgm.exe. Corresponding to flashrom svn r1188. Signed-off-by: Carl-Daniel Hailfinger <> Tested-by: Martin Rehak <> Acked-by: Michael Karcher <>
