Fix the devicetree used with sandbox. This is needed because the default (full) devicetree must be used by all phases of boot, with sandbox.

This will be confusing to a rookie. Please refer to sandbox_vpl_defconfig.

using::

using:

.. code-block:: bash

• /path/to/sandbox_vpl/tpl/u-boot-tpl -D

Please provide the full instructions:

make sandbox_vpl_defconfig make tpl/u-boot-tpl -d u-boot.dtb

• /path/to/sandbox_vpl/tpl/u-boot-tpl -d /tmp/b/sandbox_vpl/u-boot.dtb

Do we really use /tmp? We should place all build artifacts in the build directory instead.

I could not find any directory called sandbox_vpl in my /tmp directory.

I could not make the example work:

$ make sandbox_vpl_defconfig $ make $ tpl/u-boot-tpl -d u-boot.dtb

u-boot-vpl is not in tpl/ but in vpl/. The VPL example seems to need rework.

It starts up TPL (first-stage init), then VPL, then runs SPL and finally U-Boot proper, following the normal flow for a verified boot. At present, no
