Merge "plat/arm: Use common build flag for using generic sp804 driver" into integration

plat/arm: Use common build flag for using generic sp804 driver ...

SP804 TIMER is not platform specific, and current code base adds
multiple defines to use this driver. Like FVP_USE_SP804_TIMER and
FVP_VE_USE_SP804_TIMER.

This patch removes platform specific build flag and adds generic
flag `USE_SP804_TIMER` to be set to 1 by platform if needed.

SPM: Add owner field to cactus secure partitions ...

For supporting dualroot CoT for Secure Partitions a new optional field
"owner" is introduced which will be used to sign the SP with
corresponding signing domain. To demonstrate its usage, this patch adds
owners to cactus Secure Partitions.

SPM: Alter sp_gen.mk entry depending on owner of partition ...

With recently introduced dualroot CoT for SPs where they are owned
either by SiP or by Platform. SiP owned SPs index starts at SP_PKG1_ID
while Plat owned SPs index starts at SP_PKG5_ID.

This patch modifies SP makefile generator script to take CoT as an
argument and if it is "dualroot" then generates SP_PKG in order
mentioned above, otherwise generates it sequentially.

plat/arm: enable support for Plat owned SPs ...

For Arm platforms SPs are loaded by parsing tb_fw_config.dts and
adding them to SP structure sequentially, which in-turn is appended to
loadable image list.

With recently introduced dualroot CoT for SPs where they are owned
either by SiP or by Platform. SiP owned SPs index starts at SP_PKG1_ID
and Plat owned SPs index starts at SP_PKG5_ID. As the start index of SP
depends on the owner, there should be a mechanism to parse owner of a SP
and put it at the correct index in SP structure.

This patch adds support for parsing a new optional field "owner" and
based on it put SP details(UUID & Load-address) at the correct index in
SP structure.

doc: Refactor the contribution guidelines ...

Ensuring that each file changed by a patch has the correct copyright and
license information does not only apply to documentation files but to
all files within the source tree.

Move the guidance for copyright and license headers out of the paragraph
about updating the documentation to avoid any confusion.

Also do some cosmetic changes (adding empty lines, fitting in longer
lines in the 80-column limit, ...) to improve the readability of the RST
file.

doc: Stop advising the creation of Phabricator issues ...

We have noticed that Phabricator (the ticketing system on tf.org [1])
has far less visibility within the community than the mailing list [2].
For this reason, let's drop usage of Phabricator for anything else than
bug reports. For the rest, advise contributors to start a discussion on
the mailing list, where they are more likely to get feedback.

This resolves MISRA defects such as:

    The condition expression "1" does not have an essentially boolean type.

Specify signed-ness of constants ...

We relyed on the default signed-ness of constants, which is usually
signed. This can create MISRA violations, such as:

     bl1/bl1_main.c:257:[MISRA C-2012 10.8 (required)] Cast of composite
     expression off essential type signed to essential type unsigned

These constants were only used as unsigned, so this patch makes them
explicitly unsigned.

Prevent colliding identifiers ...

There was a collision between the name of the typedef in the CASSERT and
something else, so we make the name of the typedef unique to the
invocation of DEFFINE_SVC_UUID2 by appending the name that's passed into
the macro. This eliminates the following MISRA violation:

    bl1/bl1_main.c:233:[MISRA C-2012 Rule 5.6 (required)] Identifier
    "invalid_svc_uuid" is already used to represent a typedef.

This also resolves MISRA rule 5.9.

These renamings are as follows:
  * tzram -> secram. This matches the function call name as it has
  sec_mem in it's  name
  * fw_config_base -> config_base. This file does not mess with
  hw_conig, so there's little chance of confusion

Following f3ccf036ecb1ae1628 the INFO print in amu_enable is causing
a lot of print outs on UART1 in DEBUG mode especially on PSCI test
cases because CPU_ON or SUSPEND operations call:
cm_prepare_el3_exit => enable_extensions_nonsecure => amu_enable.
PSCI SUSPEND is also very frequent in linux boot cases causing test
timeout failures.

dualroot: add chain of trust for Platform owned SPs ...

For dualroot CoT there are two sets of SP certificates, one owned by
Silicon Provider(SiP) and other owned by Platform. Each certificate can
have a maximum of 4 SPs.

This patch reduces the number of SiP owned SPs from 8 to 4 and adds
the remaining 4 to Plat owned SP.
Plat owned SP certificate is signed using Platform RoT key and
protected against anti-rollback using the Non-trusted Non-volatile
counter.

Add support to generate a certificate named "plat-sp-cert" for Secure
Partitions(SP) owned by Platform.

contained hash of all 8 SPs, with this change SPs are divided into
two categories viz "SiP owned" and "Plat owned" containing 4 SPs each.

Platform RoT key pair is used for signing.
