+Armadeus APFxx are Systems On Module (SOM) based on Freescale/NXP i.MX
+processors associated with an FPGA (except on APF28). Non volatile
+data are stored in on-module NOR or NAND Flash, depending on the
+model. These SOM can be used on Armadeus development boards or with
+custom docking boards.
+Buildroot currently supports the following Armadeus platforms with the
+ * APF9328 SOM + devt boards -> armadeus_apf9328_defconfig
+ * APF27 SOM + devt board -> armadeus_apf27_defconfig
+ * APF51 SOM + devt board -> armadeus_apf51_defconfig
+ * APF28 SOM + devt board -> armadeus_apf28_defconfig
+Vanilla Linux versions are preferred to Freescale's one in these
+How to build it
+Let's say you own an APFxx SOM with it's corresponding development
+board, all you have to do is:
+ $ make armadeus_apfxx_defconfig
+where "apfxx" is the version of your SOM.
+ $ make
+Result of the build
+When the build is finished, you will end up with:
+ ├── imx**-apfxxdev.dtb 
+ ├── rootfs.jffs2 
+ ├── rootfs.tar
+ ├── rootfs.ubi 
+ ├── rootfs.ubifs 
+ └── uImage
+ Only if the kernel version used uses a Device Tree.
+ .ubi/.ubifs images are not available on APF9328 and replaced by a
+ .jffs2 one in this case.
+Building U-Boot is currently not supported in these configurations.
+You will require a serial connection to the board and a TFTP server on
+your Host PC. Assuming your server is configured for exporting
+/tftpboot/ directory, you will have to copy the generated images to
+ $ cp output/images/uImage /tftpboot/apfxx-linux.bin
+ $ cp output/images/*.dtb /tftpboot/
+ $ cp output/images/rootfs.ubi /tftpboot/apfxx-rootfs.ubi
+ $ cp output/images/rootfs.jffs2 /tftpboot/apfxx-rootfs.jffs2
+where "apfxx" is the version of your SOM, as used with _defconfigs.
+Then on your serial terminal, all you have to do is:
+* interrupt the boot process and access U-Boot console by pressing any
+ key when booting,
+* configure board and server IP addresses with "ipaddr" and "serverip"
+ environment variables,
+* if you want to update kernel:
+ BIOS > run update_kernel
+* if you want to update device tree:
+ BIOS > run update_dtb
+* if you want to update rootfs:
+ BIOS > run update_rootfs
+That's it !
