  To: buildroot; +Cc: Romain Naour

This configuration for the s6lx9 microboard was added back in March 2012
(commit 49084a198247575650c155b6f5f147fb034becc5), and has not been
updated in any significant way since then.

This defconfig still use a 4.4.7 (no longer maintained) and out of tree
devicetree (lx9_mmu.dts).

Remove its support.

Fixes:

-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
