[PATCH] Documentation: zii-vf610-dev: Fix 'halt' in openocd configuration script

[PATCH] Documentation: zii-vf610-dev: Fix 'halt' in openocd configuration script

[Cory Tusar]

When attempting to use the existing configuration file to bootstrap
an SCU4 AIB board, openocd would consistently fail on the 'halt' command
with a "Target not examined yet" error.  Dumping target information
showed that vf610.cpu1 was the active target, rather that vf610.cpu0.

Adding a command prior to the halt to explicitly set the target core
resulted in proper operation.

Tested with openocd-0.10.0+dev-00924-g16496488 on a Zodiac SCU4 AIB.

There's nothing wrong with this fix as is, however I think this is
something that should be fixed in OpenOCD itself. Both
tcl/target/imx6.cfg and tcl/target/vybrid_vf6xx.cfg are missing proper
"targets" directive, compared to e.g. tcl/target/imx7.cfg.

Thanks,
Andrey Smirnov
