checkpatch: ignore GIT_COMMIT_ID

By default, the checkpatch script requires that commit references
included in commit messages follow a predefined format. Github
merge commits do not follow this convention, causing the code
style test to fail when a new pull request is created.

This patch adds the ignore GIT_COMMIT_ID option to the checkpatch
parameters. This flag indicates the tool to ignore the commit
message format.

Juno: Disable workaround for Cortex-A57 erratum #806969

Cortex-A57 erratum #806969 applies to revision r0p0 of the CPU
but does not manifest itself on Juno r0. It is not applicable
to Juno r1 in any case.

This patch modifies the Juno platform Makefile to no longer
compile this erratum workaround in.

TBB: remove PolarSSL SHA1 functions from the binary

Commit ea4ec3aad5e1 ("TBB: use SHA256 to generate the certificate
signatures") updated the cert_create tool to generate the
signatures using SHA256 instead of SHA1. Therefore, SHA1 is no
longer required.

This patch removes the SHA1 option from the PolarSSL configuration
file. The source file sha1.c is no longer needed and has been
excluded from the build. The SHA1 functions are no longer included
in the binary, reducing the memory footprint of BL1 and BL2 by
approximately 6 KB.

Update help message printed by the Makefile

The message printed by 'make help' is incomplete. It doesn't
mention all relevant supported targets. This patch updates it.

The format of the first line of the help message has been changed
so that it no longer lists all supported targets. This eases the
maintenance as we don't need to update the list in 2 places
anymore whenever a new target is added.

Also add a reference to the user guide to get the list of
supported options.

Enable type-checking of arguments passed to printf() et al.

This patch modifies the declarations of the functions printf() et al.
and adds the right GCC attribute to request the compiler to check
the type of the arguments passed to these functions against the given
format string. This will ensure that the compiler outputs warning
messages like the following whenever it detects an inconsistency:

file.c:42: warning: format ‘%d’ expects type ‘int’, but argument 3 has type ‘long int’

It also fixes the type mismatch inconsistencies that it revealed
across the code base.

NOTE: THIS PATCH MAY FORCE PLATFORM PORTS OR SP/SPDS THAT USE THE
PRINTF FAMILY OF FUNCTIONS TO FIX ANY TYPE MISMATCH INCONSISTENCIES.

TBB: fix build target 'all' dependency on certificates

Build target 'all' fails when GENERATE_COT=1 and no BL3-3 or
BL3-0 (if required) images are specified. The reason is that,
when GENERATE_COT=1, a dependency on the certificates is added
to the target 'all', and the certificates depend on the BL3-3
and BL3-0 images, causing the build process to fail if the
images are not specified.

This patch moves the dependency on the certificates from 'all' to
'fip'. Target 'all' may be used to build the individual images.
The certificates will be created by calling the target 'fip', where
BL3-3 and BL3-0 (if required) must be specified.

Ignore C library files when checking coding style

The C library source files embedded into the Trusted Firmware
tree are not required to comply to the Linux Coding Style.
Unfortunately, 'make checkpatch' does take them into account.

This patch modifies the Makefile so that the C library source
and header files are now ignored by 'make checkpatch'.

It also instructs the checkpatch.pl script to not treat the
presence of a 'Change-Id' line in the commit message as an error.

Juno: clear DMA-330 SMMU security state

By default the SMMU for the DMA-330 is configured to mark some stream IDs
as always belonging to the Secure world. As a result, if EL1 software turns
the SMMU on, certain Non-Secure accesses get rewritten as Secure, making
them bypass translation and access Secure physical addresses directly.

Since the current Juno board firmware configures the DMA-330 hardware as
Non-Secure, rewrite the SMMU's default SSD table as well to prevent any
unexpected behaviour in EL1.

Export maximum affinity using PLATFORM_MAX_AFFLVL macro

This patch removes the plat_get_max_afflvl() platform API
and instead replaces it with a platform macro PLATFORM_MAX_AFFLVL.
This is done because the maximum affinity level for a platform
is a static value and it is more efficient for it to be defined
as a platform macro.
