This serie introduces a new board.

The first commit tweak an existing module,
and the second commit introduces the new board.

v3 --> v4
- remove qoriq-cadence-dp-firmware part
- use imx_v8_defconfig from LSDK instead of arm64 default

v2 --> v3
- restore my SoB
- add Reviewed-by Giulio Benetti

v1 --> v2
- add missing udev rules
- improved commit messages
- tweak readme.txt
  - of=/dev/sdX
- minor cleanup in defconfig
  - BR2_TOOLCHAIN_BUILDROOT_GLIBC becomes BR2_TOOLCHAIN_BUILDROOT_WCHAR
  - BR2_PACKAGE_BUSYBOX_SHOW_OTHERS removed

[Buildroot] [PATCH v4 1/2] boot/arm-trusted-firmware: allow to generate BL2 from RCW

[Francois Perrad]

This patch adds option BR2_TARGETARM_TRUSTED_FIRMWARE_RCW that allows
TF-A to encapsulate a pre-loader RCW (Reset Configuration Word) file
into BL2.

Upcoming NXP QorIQ family board needs this option.

Thanks, I have applied with some changes.

I have moved this option further down, next to the options where we can
say what BL32 to use, what BL33 to use. It made more sense to me than
to have the option in the middle of the list of images to build.

> +	bool "Include RCW"

Changed to "Include NXP RCW" to hint it's some NXP-specific stufff.

> +	select BR2_PACKAGE_HOST_QORIQ_RCW

Changed to "depends on". Indeed, sub-options of
BR2_PACKAGE_HOST_QORIQ_RCW must be set for this to work correctly, so
the user needs to be aware that qoriq-rcw is used.

Thanks!

+
+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.

Here ^^^ there is a double Reviewed-by:
I think that the Maintainer that will commit this patch could reword it.

I dropped this since we're now using glibc by default.

I added:

BR2_PACKAGE_HOST_QORIQ_RCW=y

because the arm-trusted-firmware now depends on qoriq-rcw instead of
selecting it.

Applied to next with those two changes!

Thanks!
