serial port

[s.bou...@free.fr]

Hi, I read in [1] that the serial console is activated on the Loongson platform.

See:

 	[MACH_LOONGSON_UNKNOWN]         {},
-	[MACH_LEMOTE_FL2E]              {PORT(4), {} },
-	[MACH_LEMOTE_FL2F]              {PORT(3), {} },
-	[MACH_LEMOTE_ML2F7]             {PORT_M(3), {} },
-	[MACH_LEMOTE_YL2F89]            {PORT_M(3), {} },
-	[MACH_DEXXON_GDIUM2F10]         {PORT_M(3), {} },
-	[MACH_LEMOTE_NAS]               {PORT_M(3), {} },
-	[MACH_LEMOTE_LL2F]              {PORT(3), {} },
+	[MACH_LEMOTE_FL2E]              {PORT(4, 1843200), {} },
+	[MACH_LEMOTE_FL2F]              {PORT(3, 1843200), {} },
+	[MACH_LEMOTE_ML2F7]             {PORT_M(3, 3686400), {} },
+	[MACH_LEMOTE_YL2F89]            {PORT_M(3, 3686400), {} },
+	[MACH_DEXXON_GDIUM2F10]         {PORT_M(3, 3686400), {} },
+	[MACH_LEMOTE_NAS]               {PORT_M(3, 3686400), {} },
+	[MACH_LEMOTE_LL2F]              {PORT(3, 1843200), {} },
+	[MACH_LEMOTE_A1004]             {PORT_M(2, 33177600), {} },
+	[MACH_LEMOTE_A1101]             {PORT_M(2, 25000000), {} },
+	[MACH_LEMOTE_A1201]             {PORT_M(2, 25000000), {} },
+	[MACH_LEMOTE_A1205]             {PORT_M(2, 25000000), {} },

However, various users reported the this is a quite tricky issue (see [2] and [3]).

Does anyone has confirmed the serial console on the 8133 laptop (1004 model, 3A cpu) and the Yeeloong laptop (8089, 2F CPU)?

Does it requires soldering (as it seems to be the case for the Yeeloong laptop) or could we use the USB port?
