Sanitise includes across codebase
...
Enforce full include path for includes. Deprecate old paths.
The following folders inside include/lib have been left unchanged:
- include/lib/cpus/${ARCH}
- include/lib/el3_runtime/${ARCH}
The reason for this change is that having a global namespace for
includes isn't a good idea. It defeats one of the advantages of having
folders and it introduces problems that are sometimes subtle (because
you may not know the header you are actually including if there are two
of them).
For example, this patch had to be created because two headers were
called the same way: e0ea0928d5b7 ("Fix gpio includes of mt8173 platform
to avoid collision."). More recently, this patch has had similar
problems: 46f9b2c3a282 ("drivers: add tzc380 support").
This problem was introduced in commit 4ecca33988b9 ("Move include and
source files to logical locations"). At that time, there weren't too
many headers so it wasn't a real issue. However, time has shown that
this creates problems.
Platforms that want to preserve the way they include headers may add the
removed paths to PLAT_INCLUDES, but this is discouraged.

Standardise header guards across codebase
...
All identifiers, regardless of use, that start with two underscores are
reserved. This means they can't be used in header guards.
The style that this project is now to use the full name of the file in
capital letters followed by 'H'. For example, for a file called
"uart_example.h", the header guard is UART_EXAMPLE_H.
The exceptions are files that are imported from other projects:
- CryptoCell driver
- dt-bindings folders
- zlib headers

rockchip/rk3399: Add watchdog support in pmusram
...
To catch early hangs in resume, this sets up the watchdog before
anything else in the pmusram code (ignoring setting up the stack...).
This uses hard coded settings for the watchdog until the proper
watchdog restore later on in the firmware/kernel.
This also restores the old watchdog register values before the PLLs
are restored to make sure we don't temporarily switch over to a 1/3s
timeout on the watchdog when the pclk_wdt goes from 4MHz to 100MHz.

rockchip: disable watchdog during suspend
...
The CA53 and CM0 WDT clock gating in rk3399 SGRF, and ATF is in charge of
it because the kernel can't touch SGRF.
Basically the WDT didn't stop at suspend time, it just switched from the
24M to the 32k clock. That meant that the WDT would fire if you slept for
long enough. In other word, the watchdog timer over count will increase to
750 (24*1000/32) times.
The RK3399 HW watchdog interval is 21 seconds. When machine enters the
suspend, the watchdog will reset the system after 35.7 (750/21) hours.
BUG=chrome-os-partner:59257
TEST=daisydog checked and set value, powerd_dbus_suspend to verify.

rockchip: clear the power mode status via M0
...
Due to the PMU design, the PMU may not clear the WAKEUP bit after
wakeup, therefore, the state machine at the power mode may enter
the infinite loop during WFI.
There is a solution that we can use the M0 to monitor the WAKEUP
bit and clear it during power mode, then the state machine will be
recovered immediately. Then, the DUT can exit the WFI normally.

multi-cores ARM SoCs.
This patch adds support to boot the Trusted Firmware on RK3368/RK3399
SoCs, and adds support to boot secondary CPUs, enter/exit core
power states for all CPUs in the slow/fast clusters.
This is the initial version for rockchip SoCs.(RK3368/RK3399 and next SoCs)
* Support arm gicv2 & gicv3.
* Boot up multi-cores CPU.
* Add generic CPU helper functions.
* Support suspend/resume.
* Add system_off & system_reset implementation.
* Add delay timer platform implementation.
* Support the new porting interface for the PSCI implementation.
