+STMP157-OLinuXino-LIME2
+
+Intro
+=====
+
+These are open hardware boards, all based on the STmicro STMP157 SoC.
+
+for more details about the board see the following pages:
+ - https://www.olimex.com/Products/OLinuXino/open-source-hardware
+ - https://www.olimex.com/Products/OLinuXino/STMP1/STMP157-OLinuXino-LIME2/
+
+The following defconfigs are available:
+ - olimex_stmp157_olinuxino_lime_defconfig
+
+How to build it
+===============
+
+Configure Buildroot:
+
+    $ make <board>_defconfig
+
+Compile everything and build the rootfs image:
+
+    $ make
+
+Result of the build
+-------------------
+
+After building, you should get a tree like this:
+
+    output/images/
+    +-- rootfs.ext2
+    +-- rootfs.ext4 -> rootfs.ext2
+    +-- sdcard.img
+    +-- stm32mp1xx-olinuxino-lime.dtb
+    +-- u-boot-spl.stm32
+    +-- u-boot.img
+    `-- zImage
+
+
+How to write the SD card
+========================
+
+The sdcard.img file is a complete bootable image ready to be written
+on the boot medium. To install it, simply copy the image to a uSD
+card:
+
+    # dd if=output/images/sdcard.img of=/dev/sdX
+
+Where 'sdX' is the device node of the uSD.
+
+Eject the SD card, insert it in the STMP1-OLinuXino board, and power it up.
