Normally imx-usb-loader interprets and executes the DCD table from
an uploaded image and invalidates the DCD before uploading the image
itself to prevent the i.MX ROM code from executing it again. With HAB
signed images this is not possible since invalidating the DCD table
modifies the image which also makes the signature invalid.
To support this usecase add two new options to imx-usb-loader:
The -i option allows to pass in an external config file which can be
used to setup SDRAM. The DCD table in the image can then be made empty
so that the ROM does not see a second SDRAM setup.
The -s option allows to skip interpreting the DCD table in the image.
This may when some setup stuff is still in the images DCD table but
shall be executed by the ROM and not by imx-usb-loader.

This adds a context struct to the config parser. This is a first
step to make the config parser usable from both imx-image and
imx-usb-loader which will be needed later.

Both imx-image and imx-usb-loader use their own variants of the

imx-usb-loader tries to safe memory by reading the image in chunks.
This is unnecessarily complicated. The images are small, so fully read
them into memory and store them in a single buffer. This makes handling
them a lot easier.

For signing i.MX images with HABv3 we need several certificates. Add
their pathes to Kconfig variables to make them available to the build

This imports the tools/include dir from the Kernel as of 4.5-rc1 to
barebox.
The Kernel has many useful defines and helpers which are often
duplicated in the different tools. Let's create a copy of them
in a common place for all tools.
Some files have been skipped for now as I currently see no use for them:
include/linux/filter.h
include/linux/hash.h
include/linux/rbtree.h
include/linux/rbtree_augmented.h
They can be added later if needed.

With CONFIG_BOOTM_FORCE_SIGNED_IMAGES the bootm code will refuse to boot
unsigned images. Since currently FIT is the only image type which
supports signing, this means with this option we enforce using FIT
images. All additionally passed in device trees and initrds will be
ignored, so that only the ones from the FIT image can be used.

This implementation is inspired by U-Boot's FIT support. Instead of
using libfdt (which does not exist in barebox), configuration signatures
are verified by using a simplified DT parser based on barebox's own
code.
Currently, only signed configurations with hashed images are supported,
as the other variants are less useful for verified boot. Compatible FIT
images can be created using U-Boot's mkimage tool.

So long struct bootm_data.verify is a bool which enables CRC checking
(hashing). Extend this to a enum and add support for signature checking
in the same option. This also adds the corresponding globalvar and a

In barebox the function digest_alloc() allocates a digest based on a string.
When a subsystem already uses an integer value to identify a digest it makes no
sense to create a string and pass it to digest_alloc(), where it is parsed
again. This patch adds the possibility to get a digest by an enum.
