Carl-Daniel Hailfinger	b7e01457d1	Reduce realloc syscall overhead for FT2232 and bitbang ... FT2232 ran realloc() for every executed command. Start with a big enough buffer and don't touch buffer size unless it needs to grow. Bitbang was slightly better: It only ran realloc() if buffer size changed. Still, the solution above improves performance and reliability. Corresponding to flashrom svn r780.

Carl-Daniel Hailfinger	547872b4ea	This is the bitbanging SPI driver infrastructure ... If you want support for a particular piece of hardware, just fill in a few functions in spi_bitbang_master_table. That's it. On top of this, the RayeR SPI flasher should be supportable in ~20 LOC. Tested, trace looks OK. Corresponding to flashrom svn r736.
