SimpleFB

To get SimpleFB working add this to omap4-samsung-t1.dts: 

/ {
	/* ... */
	chosen {
		#address-cells = <1>;
		#size-cells = <1>;
		ranges;

		bootargs = "console=tty0";

		framebuffer@bef00000 {
			compatible = "simple-framebuffer";
			reg = <0xbef00000 (480 * 800 * 4)>;
			width = <480>;
			height = <800>;
			stride = <(480 * 4)>;
			format = "a8r8g8b8";

			vci-supply = <&vaux3>;
			vdd3-supply = <&v1v8>;

			/*
			 * That's a lot of clocks, but it's necessary due
			 * to unused clk cleanup & no panel driver yet..
			 */
			clocks = <&l3_dss_clkctrl OMAP4_DSS_CORE_CLKCTRL 0>,
				 <&l3_dss_clkctrl OMAP4_DSS_CORE_CLKCTRL 8>,
				 <&l3_dss_clkctrl OMAP4_DSS_CORE_CLKCTRL 9>,
				 <&l3_dss_clkctrl OMAP4_DSS_CORE_CLKCTRL 10>,
				 <&l3_dss_clkctrl OMAP4_DSS_CORE_CLKCTRL 11>,
				 <&l3_div_ck>;
		};
	};
};

Now disable the following node in omap4.dtsi: 

/ {
	/* ... */
	ocp {
		/* ... */
		target-module@58000000 {
			/* ... */
			status = "disabled";
		};
	};
};

If CONFIG_FB_SIMPLE is enabled, SimpleFB should work now and you should be able to see kernel logs on the phone.

JTAG

Pin 10 is TX and pin 12 is RX.

Note: The phone won't output much through UART, all it outputs is this:
