David Cunado 5724481fdd Update ULL() macro and instances of ull to comply with MISRA
MISRA C-2012 Rule 7.3 violation: lowercase l shall not be used as literal suffixes.

This patch resolves this for the ULL() macro by using ULL suffix instead
of the ull suffix.

Leo Yan e1b27425ec Revert "Hikey960: Change to use recommended power state id format"
This reverts commit fdae60b6ba.

The commit fdae60b6ba changed the
parameter encoding for the hikey960.  However that implies a DT change
in the kernel side.  After submitting the DT change for upstreaming,
the backward compatibility issue and the interface change raise some
concerns from the Linux community about the issues related to kernel <->
ATF alignment.  There is no way to detect a mis-alignment of those
without a deep knowledge of the ATF and the kernel.  Furthermore, the
failing calls to PSCI in the idle path (because of bad parameters), will
lead to busy looping, implying: thermal issues and extra energy
consumption.

In regard of the Linux community concerns, the potential issues when the
ATF and the kernel are not aligned, it is preferable to revert the
commit.

Leo Yan fdae60b6ba Hikey960: Change to use recommended power state id format
ARM Power State Coordination Interface (ARM DEN 0022D) chapter
6.5 "Recommended StateID Encoding" defines the state ID which can be
used by platforms. The recommended power states can be presented by
below values; and it divides into three fields, every field has 4 bits
to present power states corresponding to core level, cluster level and
system level.

  0: Run
  1: Standby
  2: Retention
  3: Powerdown

This commit changes to use upper recommended power states definition on
Hikey960; and changes the power state validate function to check the
power state passed from kernel side.

Roberto Vargas e8a87acd4b Fix usage of IMAGE_BLx macros
These macros are only defined for corresponding image,
and they are undefined for other images. It means that we have
to use ifdef or defined() instead of relying on being 0 by default.

Otherwise, BL2 tries to load a BL32 image and triggers

Haojian Zhuang 2f2abcf4ba hikey960: support BL1 on hikey960 platform
Support BL1 on HiKey960 platform. When recovery mode is detected,
BL1 loads NS BL1U that flushs images into UFS. When normal boot
mode is detected, BL1 loads BL2.

Fix for https://github.com/ARM-software/tf-issues/issues/486
