2013-05-08sysfsgpio: do not try to initialise absent signalsPaul Fertser
When e.g. SRST is not specified, the current code results in assigning 0 to srst_fd and subsequently a stray '1' is output on screen on reset. Avoid this by not doing bogus initialisation.

2013-02-08jtag_interface: .speed can be NULL when not neededFranck Jullien
adapter_init (core.c) won't check speed configuration of the selected interface if it's not needed (.speed = NULL). When it's not needed, we can now omit adapter_khz in init scripts and we don't have to implement dummy handlers for speed_div and khz functions. It also removes calls to adapter_khz in interface configuration files when not used anymore.

2012-09-26drivers: new jtag bitbang driver using sysfs gpioMarc Reilly
This driver implements a bitbang jtag interface using gpio lines exported via sysfs. The aim of this driver implementation is to use system GPIOs but to avoid the need for an additional kernel driver. A config suitable for RaspberryPi is included.
