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.

efi_loader: split README.efi into two separate documents

2018-02-09T23:24:00+00:00

README.efi describes two different concepts:
* U-Boot exposing the UEFI API
* U-Boot running on top of UEFI.

This patch splits the document in two.
Religious references are removed.

The separation of the concepts makes sense before detailing the internals
of U-Boot exposing the UEFI API in a future patch.

doc: mxc_hab: Improve the config option list

2018-02-04T11:14:10+00:00

The original text is from the time that the config options were not
converted to Kconfig.

After the conversion to Kconfig only CONFIG_SECURE_BOOT and
CONFIG_CMD_DEKBLOB need to be selected by the user.

The other config options are automatically selected by the Kconfig
logic.

log: Add a way to log error-return values

2018-02-03T17:09:27+00:00

When functions return an error it propagates up the stack to the point
where it is reported. Often the error code provides enough information
about the root cause of the error that this is obvious what went wrong.

However in some cases the error may be hard to trace. For example if a
driver uses several devices to perform an operation, it may not be
obvious which one failed.

Add a log_ret() macro to help with this. This can be used to wrap any
error-return value. The logging system will then output a log record when
the original error is generated, making it easy to trace the call stack
of the error.

This macro can significantly impact code size, so its use is controlled
by a Kconfig option, which is enabled for sandbox.
