configs/ls1043a-rdb: new defconfig

This is a reference design board for the NXP LS1043A SoC.

The config is heavily based on the ls1046a-frwy_defconfig.

+***************
+NXP LS1043A-RDB
+***************
+
+This file documents the Buildroot support for the LS1043A Reference Design Board.
+
+for more details about the board and the QorIQ Layerscape SoC, see the following pages:
+  - https://www.nxp.com/design/design-center/development-boards-and-designs/LS1043A-RDB
+  - https://www.nxp.com/products/LS1043A
+
+for the NXP LDP (Linux Distribution POC), see
+  - https://www.nxp.com/design/design-center/software/embedded-software/linux-software-and-development-tools/layerscape-linux-distribution-poc:LAYERSCAPE-SDK
+
+the components provided by NXP are:
+  - rcw, lf-6.6.52-2.2.0
+  - atf (fork), lf-6.6.52-2.2.0
+  - uboot (fork), lf-6.6.52-2.2.0
+  - qoriq-fm-ucode (blob), lf-6.6.52-2.2.0
+  - linux (fork), lf-6.6.52-2.2.0
+
+Build
+=====
+
+First, configure Buildroot for the LS1043A-RDB board:
+
+  make ls1043a-rdb_defconfig
+
+Build all components:
+
+  make
+
+You will find in output/images/ the following files:
+  - bl2_sd.pbl
+  - fip.bin
+  - fsl_fman_ucode_ls1043_r1.1_106_4_18.bin
+  - fsl_fman_ucode_ls1043_r1.1_108_4_9.bin
+  - fsl-ls1043a-rdb.dtb
+  - fsl-ls1043a-rdb-sdk.dtb
+  - Image
+  - PBL.bin
+  - rootfs.ext2
+  - rootfs.ext4
+  - 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/ls1043a-rdb/genimage.cfg.
+
+Boot the LS1043A-ARDB board
+===========================
+
+To boot your newly created system:
+- insert the SD card in the SD slot of the board;
+- Configure the DIP switches
+  SW3[1:8] = 10110011
+  SW4[1:8] = 00100000
+  SW5[1:8] = 00100010
+  (SW5[1:8] and SW4[1] should be set to 001000000_0 for the SD card boot)
+- put a Micro-USB cable into the console port and connect using a terminal emulator
+  at 115200 bps, 8n1.
+- power on the board.
+
+Alternatively, SD card boot can also be selected from the uboot command prompt:
+- insert the SD card in the SD slot of the board;
+- put a Micro-USB cable into console Port and connect using a terminal emulator
+- power on the board.
+- press any key to stop at the uboot command prompt.
+- run the following uboot command
+  => cpld reset sd
