OpenOCD errors summary

TODO: verify the following errors and workarounds.


- Error: JTAG scan chain interrogation failed: all zeroes

This is solved by a board power-cycle and OpenOCD restart.

- Error: Jazelle debug entry -- BROKEN!

Restarting OpenOCD then brings it to a state where the following
occurs:

- Error: address + size wrapped(0xffffffff, 0x00000004)

This seems to be a generic error caused by GDB getting confused by
what it gets from OpenOCD, or some other GDB-related issue.

This is fixable by "nudging", i.e. "reset" + "continue" on the GDB
prompt: finally it does seem to run reliably, stepping + breakpoints.
