Subject: [PATCH  v4 21/21] gdbstub: do not split gdb_monitor_write payload
Date: Fri, 20 Dec 2019 12:04:38 +0000	[thread overview]
Message-ID: <20191220120438.16114-22-alex.bennee@linaro.org> (raw)
In-Reply-To: <20191220120438.16114-1-alex.bennee@linaro.org>

From: Damien Hedde <damien.hedde@greensocs.com>

Since we can now send packets of arbitrary length:
simplify gdb_monitor_write() and send the whole payload
in one packet.
