nrf: support debugging the PCA10056

aykevl · deadprogram · commit 4e4b5955db2d · 2020-06-08T19:54:41.000+02:00
This change adds support for `tinygo gdb` on the PCA10056.

The board is normally flashed with the MSD programmer. Debugging needs a
real debugger interface however, which is relatively simple by just
adding the right OpenOCD configuration.
