Compiling BL31 for the Allwinner platform now produces a message about
the deprecation of gic_common.c.
Follow the advice and use include gicv2.mk instead.

* changes:
  dualroot: add chain of trust for Platform owned SPs
  cert_create: add Platform owned secure partitions support

* changes:
  Specify signed-ness of constants
  Prevent colliding identifiers

This resolves MISRA defects such as:

    plat/common/plat_bl1_common.c:63:[MISRA C-2012 Rule 14.4 (required)]
    The condition expression "1" does not have an essentially boolean type.

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.

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 f3ccf036

 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.

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.
Earlier a single certificate file "sip-sp-cert" was generated which
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.

This patch fixes the bug when AMUv1 group1 counters was
always assumed being implemented without checking for its
presence which was causing exception otherwise.
The AMU extension code was also modified as listed below:
- Added detection of AMUv1 for ARMv8.6
- 'PLAT_AMU_GROUP1_NR_COUNTERS' build option is removed and
number of group1 counters 'AMU_GROUP1_NR_COUNTERS' is now
calculated based on 'AMU_GROUP1_COUNTERS_MASK' value
- Added bit fields definitions and access functions for
AMCFGR_EL0/AMCFGR and AMCGCR_EL0/AMCGCR registers
- Unification of amu.c Aarch64 and Aarch32 source files
- Bug fixes and TF-A coding style compliant changes.

BL31 binary size is aligned to 4KB because of the
code in include\plat\arm\common\arm_reclaim_init.ld.S:
    __INIT_CODE_UNALIGNED__ = .;
    . = ALIGN(PAGE_SIZE);
    __INIT_CODE_END__ = .;
with all the zero data after the last instruction of
BL31 code to the end of the page.
This causes increase in size of BL31 binary stored in FIP
and its loading time by BL2.
This patch reduces the size of BL31 image by moving
page alignment from __INIT_CODE_END__ to __STACKS_END__
which also increases the stack size for secondary CPUs.

MISRA defect cleanup and general code cleanup in mem_region.c and
semihosting.c.  This task also called for cleanup of the ARM NOR flash
driver but that was removed at some point since the Jira task was
created.  This patch fixes all MISRA defects in these files except for a
few "Calling function "console_flush()" which returns error information
without testing the error information." errors which can't really be
avoided.

If the user tries to change BUILD_BASE to put the build products outside
the build tree the compile will fail due to hard coded assumptions that
$BUILD_BASE is a relative path. Fix by using $(abspath $(BUILD_BASE))
to rationalize to an absolute path every time and remove the relative
path assumptions.

This patch also adds documentation that BUILD_BASE can be specified by
the user.
