+U-Boot for the Congatec Conga-QEVAl Evaluation Carrier board
+
+This file contains information for the port of U-Boot to the Congatec
+Conga-QEVAl Evaluation Carrier board.
+
+1. Boot source, boot from SD card
+---------------------------------
+
+This version of u-boot works only on the SD card. By default, the
+Congatec board boot from the SPI-NOR.
+With the uboot version provided with the board you can write boot
+registers to force the board to reboot and boot from the SD slot:
+
+conga-QMX6 U-Boot > mw.l 0x20d8040 0x3850
+conga-QMX6 U-Boot > mw.l 0x020d8044 0x10000000
+conga-QMX6 U-Boot > reset
+resetting ...
+
+The the board will reboot and, if you burnt your SD correctly the
+board (see (2) for instructions) will use u-boot that live into the SD
+card.
+
+2. Build
+--------
+
+To build U-Boot for the Congatec board:
+
+ make cgtqmx6_config
+ make u-boot.imx
+
+To copy the resulting u-boot.imx to the SD card:
+
+ sudo dd if=u-boot.imx of=/dev/sXx bs=512 seek=2&&sudo sync
+
+Note: Replace sXx with the device representing the SD card in your system.
