imx: hab: Convert DCD non-NULL error to warning

2018-03-13T11:51:32+00:00

commit 8c4037a09a5c ("imx: hab: Ensure the IVT DCD pointer is Null prior
to calling HAB authenticate function.") makes the DCD field being NULL a
dependency.

This change though will break loading and executing of existing pre-signed
binaries on a u-boot update i.e. if this change is deployed on a board you
will be forced to redo all images on that board to NULL out the DCD.

There is no prior guidance from NXP that the DCD must be NULL similarly
public guidance on usage of the HAB doesn't call out this NULL dependency
(see boundary devices link).

Since later SoCs will reject a non-NULL DCD there's no reason to make a
NULL DCD a requirement, however if there is an actual dependency for later
SoCs the appropriate fix would be to do SoC version checking.

Earlier SoCs are capable (and happy) to authenticate images with non-NULL
DCDs, we should not be forcing this change on downstream users -
particularly if it means those users now must rewrite their build systems
and/or redeploy signed images in the field.

to calling HAB authenticate function.")

doc: mxc_hab: Move HAB related info to the appropriate doc

2018-03-11T15:00:16+00:00

Currently the High Assurance Boot procedure is documented in two
places:

- doc/README.imx6
- doc/README.mxc_hab

It is better to consolidate all HAB related information into
README.mxc_hab file, so move the content from README.imx6 to
README.mxc_hab.

imx: hab: Make usage of packed attribute consistent

2018-03-11T15:00:00+00:00

commit cd2d46003ce1 ("arm: imx: hab: Add IVT header definitions") declares
struct ivt_header as "__attribute__((packed))".

commit ed286bc80e9d ("imx: hab: Check if CSF is valid before
authenticating image") declares struct hab_hdr with __packed.

This patch makes the __packed convention consistent.

imx: hab: Fix usage of packed attribute

commit ed286bc80e9d ("imx: hab: Check if CSF is valid before authenticating

With my compiler "gcc version 7.2.1 20171011 (Linaro GCC 7.2-2017.11)" we
get:
