"reset" without arguments now execute a "reset run".

the reset mode argument to the target command is deprecated(ignored w/error message).

Endianess may be @option{little} or @option{big}.
The reset_mode specifies what should happen to the target when a reset occurs:

@item @b{reset_halt}
@cindex reset_halt
Immediately request a target halt after reset. This allows targets to be debugged
from the very first instruction. This is only possible with targets and JTAG
interfaces that correctly implement the reset signals.
@item @b{reset_init}
@cindex reset_init
Similar to @option{reset_halt}, but executes the script file defined to handle the
'reset' event for the target. Like @option{reset_halt} this only works with
correct reset implementations.
@item @b{reset_run}
@cindex reset_run
Simply let the target run after a reset.
@item @b{run_and_halt}
@cindex run_and_halt
Let the target run for some time (default: 1s), and then request halt.
@item @b{run_and_init}
@cindex run_and_init
A combination of @option{reset_init} and @option{run_and_halt}. The target is allowed
to run for some time, then halted, and the @option{reset} event script is executed.
