+NVIDIA Jetson TX2
+
+Intro
+=====
+
+This configuration adds support for the Jetson TX2 devkit. It should be
+compatible with the other Jetson-series boards as well, but has not yet been
+tested. (Other boards include the tx2i, nano...)
+
+Building
+========
+
+Configure Buildroot
+-------------------
+
+For Jetson TX2:
+
+  $ make jetsontx2_defconfig
+
+Build the rootfs
+----------------
+
+You may now build your rootfs with:
+
+  $ make
+
+
+Flashing
+========
+
+Once the build process is finished you will have the target binaries in the
+output/images directory, with a symlink to linux4tegra.
+
+Flashing to the internal eMMC is done by booting to the official recovery mode,
+and flashing the system from there. The default factory-flashed TX2 is suitable.
+
+There are a lot of cases where the TX2 will not boot properly unless all of the
+peripherals are fully disconnected, power is disconnected, everything fully
+resets, and then the power is introduced back again.
+
+The recovery mode of the Jetson is used to flash. Entering recovery:
+
+ - Start with the machine powered off + fully unplugged.
+ - Plug in the device to power, and connect a HDMI display.
+ - Connect a micro-USB cable from the host PC to the target board.
+ - Power on the device by holding the start button until the red light is lit.
+ - Hold down the RST button and REC button simultaneously.
+ - Release the RST button while holding down the REC button.
+ - Wait a few seconds, then release the REC button.
+
+To flash over USB:
+
+```
+cd output/images/linux4tegra
+sudo bash ./flash.sh \
+     -I ../rootfs.ext2 \
+     -K ../Image \
+     -L ../u-boot-dtb.bin \
+     -C "ramdisk_size=100000 net.ifnames=0 elevator=deadline" \
+     -d ../tegra186-quill-p3310-1000-c03-00-base.dtb \
+     jetson-tx2-devkit mmcblk0p1
+```
+
+This will run the `flash.sh` script from L4T, and will setup the kernel, u-boot,
+persist + boot-up partition mmcblk0p1. This may overwrite your existing work so
+use it for initial setup only.
+
+## Bootup Process
+
+The TX2 and recent boards boot from the internal eMMC, at mmcblk0p1. The Jetson
+Nano can boot to a SD card.
+
+A "secure boot" process is used, with multiple bootloaders:
+
+ - BootROM -> MB1 (TrustZone)
+ - MB2/BPMP -> (Non-Trustzone)
+ - Cboot (uses Little Kernel)
+ - Uboot
+ - Kernel
+
+Uboot is flashed to the mmcblk0p1 emmc partition.
+
+Cboot could be compiled from source, and the source is available from the
+official sources, however, we do not (yet) compile cboot.
