Subject: drivers/bitbang: blink LED on SWD
X-Git-Url: https://git.gag.com/?a=commitdiff_plain;h=3e6f4f8b213ce2c61b052b16606cfc81ba6d7cc4;p=fw%2Fopenocd

drivers/bitbang: blink LED on SWD

The blinking was implemented for JTAG only.

Extend it to SWD.
There is no error check on SWD exchange. Add a FIXME for further
fix.
