Subject: jtag: the post TAP state is now passed to the drivers
X-Git-Tag: v0.5.0-rc1~893
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=761d4555b8f8c8eb2b899dee16584656a43b6444;p=openocd

jtag: the post TAP state is now passed to the drivers

after clocking out a tms sequence, then the TAP will be
in some state. This state is now handed to the drivers.

TAP_INVALID is a possible state after a TMS sequence if
switching to SWD.
