+**************
+NXP LS1028ARDB
+**************
+
+This file documents the Buildroot support for the LS1028A Reference Design Board.
+
+for more details about the board and the QorIQ Layerscape SoC, see the following pages:
+  - https://www.nxp.com/design/qoriq-developer-resources/layerscape-ls1028a-reference-design-board:LS1028ARDB
+  - https://www.nxp.com/LS1028A
+
+Build
+=====
+
+First, configure Buildroot for the LS1028ARDB board:
+
+  make ls1028ardb_defconfig
+
+Build all components:
+
+  make
+
+You will find in output/images/ the following files:
+  - bl2_sd.pbl
+  - fip.bin
+  - fsl-ls1028a-rdb.dtb
+  - Image
+  - PBL.bin
+  - rootfs.ext2
+  - rootfs.ext4 -> rootfs.ext2
+  - sdcard.img
+  - u-boot.bin
+
+Create a bootable SD card
+=========================
+
+To determine the device associated to the SD card have a look in the
+/proc/partitions file:
+
+  cat /proc/partitions
+
+Buildroot prepares a bootable "sdcard.img" image in the output/images/
+directory, ready to be dumped on a SD card. Launch the following
+command as root:
+
+  dd if=output/images/sdcard.img of=/dev/sdX
+
+*** WARNING! This will destroy all the card content. Use with care! ***
+
+For details about the medium image layout, see the definition in
+board/freescale/ls1028ardb/genimage.cfg.
+
+Boot the LS1028ARDB board
+=========================
+
+To boot your newly created system:
+- insert the SD card in the SD slot of the board;
+- Configure the switches SW2[1:4] = 1000 (select SD Card boot option)
+- put a DB9F cable into the UART1 Port and connect using a terminal
+  emulator at 115200 bps, 8n1;
+- power on the board.
