Signalyzer: H2 and H4 support
This patch includes partial support for these new JTAG adapters. More complete support will require updates to the libftdi code, for EEPROM access. [dbrownell@users.sourceforge.net: fix whitespace, linelen, etc ] Signed-off-by: David Brownell <dbrownell@users.sourceforge.net>
