scripts: imx-image: Allow to create HAB signed images suitable for USB upload ...

For USB upload we must execute the DCD table manually and
invalidate the DCD table in the uploaded image afterwards
to prevent the ROM from executing the DCD data again. Doing this
changes the image and thus also invalidates the signature. To
make HAB signed images suitable for USB upload possible we add an
option to create HAB signed images suitable for USB upload. With
this option the image is created like this:

- The image is created like usual, but with already invalidated DCD
  data (DCD length is set to zero)
- This image is then signed using the CST
- After this the DCD data is made valid (Set DCD length to the real
  length)

imx-usb-loader now finds valid DCD data, executes it and by invalidating
the DCD data it restores the state the image had during signing.

scripts: imx-usb-loader: Use dcd len to invalidate dcd data ...

We invalidate the dcd data in the uploaded image since we already
processed it manually. To do so we have set the dcd pointer to 0.
Doing it this way prevents the ROM from executing the HAB code in
debug mode. Use the dcd length instead to invalidate the dcd data.

scripts: imx: Generate signed images with imx-image ...

The imx-image tool can now generate signed images itself, so we can
switch to this mechanism:

- Move the CSF templates to header files which can be included by the
  flash config files
- remove images/Makefile.imxhabv4 which is no longer necessary.

scripts: imx: Allow to create signed images ...

This patch allows to call CST directly from imx-image to create signed
images. CST is called whenever the config file contains the hab <str>
commands which means a CSF is generated.
Calling CST requires some quirks. First of all CST returns successfully
whenever a CSF exists, no matter is the CSF actually contains something
sensible or not. So to detect if CST has been called successfully we
have to check if it generated output, not if it returned successfully.
Then CST uses csfsig.bin as a temporary file which breaks when the tool
is called multiple times at once, something which often happens in
parallel builds. We therefore have to lock accesses to this file using
flock().

scripts: imx: Create CSF files from imx config file ...

This is the first step to support creating signed images directly
with the imx-image tool. i.MX images must be signed using the Freescale
CST tool. CST needs informations already present in the imx-image tool,
so it's convenient to call CST directly from imx-image.
CST takes CSF files (Command Sequence Files) as input. This patch
supports generating CSF files from the imx-image configuration file.
This adds three new commands to the config file:

hab <str>:  All options to the hab command are directly passed through to
            the CSF.
hab_blocks: This generates the "Blocks =" line in the CSF. This is the
            place where the CSF needs information which is contained in
	    the imx-image tool: The image size, the image filename and
	    the load address.
super_root_key <file>: For HABv3 the super root key hash is needed in
                       the i.MX flash header. This command is used to
		       specify the path to the super root key. Needed
		       for HABv3 only.

    Very rarely, the KSZ9031 will appear to complete autonegotiation, but
    will drop all traffic afterwards.  When this happens, the idle error
    count will read 0xFF after autonegotiation completes.  Reset the PHY
    when in that state.

bitops: Fix shift overflow in GENMASK macros ...

Based on the original patch for linux:

	commit 00b4d9a
	Author: Maxime COQUELIN <maxime.coquelin@st.com>
	Date:   Thu Nov 6 10:54:19 2014

	On some 32 bits architectures, including x86, GENMASK(31, 0) returns 0
	instead of the expected ~0UL.

	This is the same on some 64 bits architectures with GENMASK_ULL(63, 0).

	This is due to an overflow in the shift operand, 1 << 32 for GENMASK,
	1 << 64 for GENMASK_ULL.

sequentialy numbered "/dev/phy%d" with "/dev/mdio%d-phy%02x". This way

schematic) corresponds to which device in /dev.

Also, replace asprintf with xasprintf to provide some form of memory
