-3. Mainline status
+3. Building
+
+ ex. configure and build for zc702 board
+ $ make zynq_zc702_config
+ $ make
+
+4. Bootmode
+
+Zynq has a facility to read the bootmode from the slcr bootmode register
+once user is setting through jumpers on the board - see page no:1546 on [5]
+
+All possible bootmode values are defined in Table 6-2:Boot_Mode MIO Pins
+on [5].
+
+board_late_init() will read the bootmode values using slcr bootmode register
+at runtime and assign the modeboot variable to specific bootmode string which
+is intern used in autoboot.
+
+SLCR bootmode register Bit[3:0] values
+#define ZYNQ_BM_NOR 0x02
+#define ZYNQ_BM_SD 0x05
+#define ZYNQ_BM_JTAG 0x0
+
+"modeboot" variable can assign any of "norboot", "sdboot" or "jtagboot"
+bootmode strings at runtime.
