* Reduce realloc syscall overhead for FT2232 and bitbangCarl-Daniel Hailfinger2009-11-251-2/+5
| | | | | | | | | | | | 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.

* This is the bitbanging SPI driver infrastructureCarl-Daniel Hailfinger2009-09-281-0/+161
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. Signed-off-by: Carl-Daniel Hailfinger <c-d.hailfinger.devel.2006@gmx.net> Acked-by: Uwe Hermann <uwe@hermann-uwe.de>
