+This is the buildroot board support for the Avnet Spartan6 LX9 MicroBoard.
+
+The Avnet S6LX9 Microboard is a small USB-Stick sized module containing
+a Spartan6 FPGA capable of running the Microblaze softcore processor
+together with RAM and FLASH memory.
+
+The board can be bought from Avnet (avnet.com) or from Trenz Electronic
+(www.trenz-electronic.de) for a low price.
+
+To run the Linux built with buildroot you have to install the FPGA bitfile
+and u-boot as described in the tutorial AvtS6LX9MicroBoard_SW302_PetaLinux
+available on http://www.em.avnet.com/s6microboard
+
+On this site also is a forum containing information on how to build your own
+Microblaze processor for the Microboard.
+
+The image file (default name is simpleImage.lx9_mmu.ub) has to be copied
+to your tftp folder (often /tftpboot/) or can be programmed into the
+board's SPI flash.
+
+Sample session:
+
+$ make s6lx9_microboard_defconfig
+$ make
+$ cp build/linux-<version>/arch/microblaze/boot/simpleImage.lx9_mmu.ub /tftpboot/br12.2a.ub
+$ minicom
