To: buildroot; +Cc: Maxime Leroy, Vladimir Oltean, Vincent Jardin
From: Vladimir Oltean <olteanv@gmail.com>
Add Buildroot support for the NXP LX2160A-RDB (reference design board).
This is configured here to boot from the SD card. To my surprise, NXP
RCWs for LX2160A rev2 silicon don't have a pre-existing example for SD
boot, so until one is available, include the RCW through board files.
The boot uses U-Boot's bootstd framework with extlinux.conf. The DPAA2
Management Complex firmware is loaded from the filesystem during U-Boot
board init. EFI boot support is disabled since we use extlinux.

Changes v6 -> v7:
- resend with correct authorship (v6 was sent with wrong sender
addresses)
Changes v5 -> v6:
- increase BR2_TARGET_ROOTFS_EXT2_SIZE from 130M to 256M: on
current master the rootfs needs about 148M (Linux ~100M,
eudev/hwdb ~25M)

+**************
+NXP LX2160ARDB
+**************
+
+This file documents the Buildroot support for the LX2160A Reference Design Board.
+
+For more details about the board and the QorIQ Layerscape SoC, see the
+following pages (notably the "LX2160A Reference Design Board Getting Started
+Guide", for which this guide serves as an addition, not a replacement):
+ - https://www.nxp.com/design/design-center/software/qoriq-developer-resources/layerscape-lx2160a-reference-design-board:LX2160A-RDB
+ - https://www.nxp.com/LX2160A
+
+Layerscape platforms are officially supported by NXP under the Layerscape
+Debian Linux SDK (LDLSDK). This uses components from Linux Factory (project
+common with i.MX), but has a slower release cadence than LF. The currently used
+tag is lf-6.12.34-2.1.0, which is in line with the latest LF tag. Generally, in
+Buildroot, the latest Linux Factory release tag is always used, which may be
+considered pre-release software, as it may contain features which are not yet
+documented, and it generally undergoes less testing.
+
+For the software Layerscape Debian Linux SDK User Guide, see:
+ - https://docs.nxp.com/bundle/UG10143/page/topics/about_this_document.html
+ - https://www.nxp.com/docs/en/user-guide/UG10143.pdf
+
+The components from NXP are:
+ - atf (fork), lf-6.12.34-2.1.0
+ - linux (fork), lf-6.12.34-2.1.0
+ - qoriq-ddr-phy-binary (blob), lf-6.12.34-2.1.0
+ - qoriq-firmware-inphi (blob), static commit
+ - qoriq-mc-binary (blob), mc_release_10.39.0
+ - qoriq-mc-utils, mc_release_10.39.0
+ - qoriq-rcw, lf-6.12.34-2.1.0
+ - qoriq-restool, lf-6.12.34-2.1.0
+ - uboot (fork), lf-6.12.34-2.1.0
+
+Build
+=====
+
+First, configure Buildroot for the LX2160ARDB board:
+
+ make lx2160ardb_defconfig
+
+Build all components:
+
+ make
+
+You will find in output/images/ the following files:
+ - bl2_sd.pbl - RCW + ATF BL2 stage
+ - dpc-usxgmii.dtb - the default DPC file
+ - dpc-warn.dtb
+ - dpl-2dpni.dtb
+ - dpl-eth.19.dtb - the default DPL file
+ - fip_ddr.bin - DDR PHY firmware
+ - fip.bin - U-Boot packaged as ATF payload
+ - fsl-lx2160a-rdb.dtb
+ - Image
+ - in112525-phy-ucode.txt - Firmware file for 25GbE SFP+ retimer
+ - mc.itb - MC firmware
+ - PBL.bin
+ - rootfs.ext2
+ - rootfs.ext4
+ - sdcard.img
+ - u-boot.bin
+ - uboot-env.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
+
+The SD card image can also be programmed from a live system running U-Boot:
+
+ => setenv autoload off && tftp $load_addr sdcard.img && mmc dev 0 && mmc write $load_addr 0 0x80000
+
+*** WARNING! This will destroy all the card content. Use with care! ***
+
+For details about the medium image layout, see the definition in
+board/freescale/lx2160ardb/genimage.cfg.
+
+Boot the LX2160ARDB board
+=========================
+
+To boot your newly created system:
+- insert the SD card in the SD slot of the board;
+- Configure the switches SW1[1:4] = 0b1000 (select SD Card boot option),
+ or alternatively, run "qixis_reset sd" from a U-Boot booted from a different
+ boot source (NOR, eMMC etc).
+- put a DB9F cable into the UART1 Port and connect using a terminal
+ emulator at 115200 bps, 8n1;
+- power on the board.
+
+The DPL and DPC files provided by NXP are not maximal configurations.
+They only contain a static description for:
+- the 40GbE QSFP+ MAC2 (which implicitly has MAC_LINK_TYPE_FIXED, because its
+ entry is missing from the DPC, and this means that the link state is provided
+ by the MC firmware)
+- the 1GbE RGMII MAC17 (specified as MAC_LINK_TYPE_PHY in the DPC, which means
+ that the link state is provided by phylink).
+
+The extra interfaces routed to front panel ports are endpmac3, endpmac4,
+endpmac5, endpmac6 and endpmac18. Among the more usual networking choices, one
+could create individual DPNIs for each MAC:
+
+$ ls-addni dpmac.3 && ls-addni dpmac.4 && ls-addni dpmac.5 && ls-addni dpmac.6 && ls-addni dpmac.18
+
+or a DPSW object to accelerate L2 forwarding between them:
+
+$ ls-addsw --num-ifs=4 --max-fdbs=4 --flooding-cfg=DPSW_FLOODING_PER_FDB \
+ --broadcast-cfg=DPSW_BROADCAST_PER_FDB dpmac.3 dpmac.4 dpmac.5 dpmac.6
+$ ip link add br0 type bridge vlan_filtering 1 && ip link set br0 up

+Once the runtime configuration is satisfactory, it can be converted back into a
+permanent DPL file which can be plugged back into the build system:
+
+$ restool dprc generate-dpl > dpl-new.dts
+
+Using the device tree compiler (dtc), the new DPL can be transformed into a
+.dtb file and deployed as a custom networking configuration upon the next boot.
