u-boot

upstream u-boot with additional patches for our devices/boards: https://lists.denx.de/pipermail/u-boot/2017-March/282789.html (AXP crashes) ; Gbit ethernet patch for some LIME2 revisions ; with SPI flash support

History

Tom Rini 4549e789c1 SPDX: Convert all of our multiple license tags to Linux Kernel style When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have multiple licenses (in these cases, dual license) declared in the SPDX-License-Identifier tag. In this case we change from listing "LICENSE-A LICENSE-B" or "LICENSE-A or LICENSE-B" or "(LICENSE-A OR LICENSE-B)" to "LICENSE-A OR LICENSE-B" as per the Linux Kernel style document. Note that parenthesis are allowed so when they were used before we continue to use them. Reviewed-by: Fabio Estevam <fabio.estevam@nxp.com> Signed-off-by: Tom Rini <trini@konsulko.com>		6 years ago

README

Here is the step-by-step to boot to U-Boot on RK3368-uQ7

Get the Source and build ATF
============================

  > git clone git://git.theobroma-systems.com/arm-trusted-firmware.git
  > cd arm-trusted-firmware
  > make CROSS_COMPILE=aarch64-linux-gnu- PLAT=rk3368 bl31
  > cp build/rk3368/release/bl31.bin ../u-boot/bl31-rk3368.bin

Configure U-Boot
================

  > cd ../u-boot
  > make lion-rk3368_defconfig

Build the TPL/SPL stage
=======================

  > make CROSS_COMPILE=aarch64-unknown-elf- ARCH=arm
  > tools/mkimage -n rk3368 -T rksd -d tpl/u-boot-tpl.bin spl-3368.img
  > cat spl/u-boot-spl-dtb.bin >> spl-3368.img

Build the full U-Boot and a FIT image including the ATF
=======================================================

  > make CROSS_COMPILE=aarch64-unknown-elf- ARCH=arm u-boot.itb

Flash the image
===============

Copy the SPL to offset 32k and the FIT image containing the payloads
(U-Boot proper, ATF, devicetree) to offset 256k card.

SD-Card
-------

  > dd if=spl-3368.img of=/dev/sdb seek=64
  > dd if=u-boot.itb of=/dev/sdb seek=512

eMMC
----

rkdeveloptool allows to flash the on-board eMMC via the USB OTG interface with
help of the Rockchip loader binary.

  > git clone https://github.com/rockchip-linux/rkdeveloptool
  > cd rkdeveloptool
  > autoreconf -i && && ./configure && make
  > git clone https://github.com/rockchip-linux/rkbin.git
  > ./rkdeveloptool db rkbin/rk33/rk3368_loader_v2.00.256.bin
  > ./rkdeveloptool wl 64 ../spl.img
  > ./rkdeveloptool wl 512 ../u-boot.itb


If everything went according to plan, you should see the following
output on UART0:
