Antonio Nino Diaz 09d40e0e08 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: e0ea0928d5 ("Fix gpio includes of mt8173 platform
to avoid collision."). More recently, this patch has had similar
problems: 46f9b2c3a2 ("drivers: add tzc380 support").

This problem was introduced in commit 4ecca33988 ("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.

Antonio Nino Diaz c3cf06f1a3 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

Daniel Boulby a08a201430 Ensure the flow through switch statements is clear
Ensure case clauses:
*   Terminate with an unconditional break, return or goto statement.
*   Use conditional break, return or goto statements as long as the end
    of the case clause is unreachable; such case clauses must terminate
    with assert(0) /* Unreachable */ or an unconditional  __dead2 function
    call
*   Only fallthough when doing otherwise would result in less
    readable/maintainable code; such case clauses must terminate with a
    /* Fallthrough */ comment to make it clear this is the case and
    indicate that a fallthrough is intended.

This reduces the chance of bugs appearing due to unintended flow through a
switch statement

Paul Kocialkowski fb83888b61 rockchip: Move stdint header to the offending header file
The stdint header was introduced to rk3399's plat_sip_calls.c in order
to fix missing stdint definitions. However, ordering headers
alphabetically caused the fix to be ineffective, as stint was then
included after the offending header file (dfs.h).

Move the stdint include to that header to properly fix the issue.

Derek Basehore 5b886432dc 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.

Caesar Wang c3710ee7a2 rockchip/rk3399: fixes the typo and the WARNINGS during suspend/resume
This patch fixes the two things as follows:

1) rk3399_flash_l2_b" seems to be a typo. That's "flush", not "flash".

2) fixes the warnings log.
We always hit the warnings thing during the suspend, as below log:
..
[   51.022334] CPU5: shutdown
[   51.025069] psci: CPU5 killed.
INFO:    sdram_params->ddr_freq = 928000000
WARNING: rk3399_flash_l2_b:reg 28830380,wait

When the L2 completes the clean and invalidate sequence, it asserts the
L2FLUSHDONE signal. The SoC can now deassert L2FLUSHREQ signal and then
the L2 deasserts L2FLUSHDONE.

Then, a loop without a delay isn't really great to measure time. We should
probably add a udelay(10) or so in there and then maybe replace the WARN()
after the loop. In the actual tests, the L2 cache will take ~4ms by
default for big cluster.

In the real world that give 10ms for the enough margin, like the
ddr/cpu/cci frequency and other factors that will affect it.

Xing Zheng 43f52e92e4 rockchip: rk3399: disable training modules after DDR DFS
On resume, we use the DFS hardware to switch frequency index,
followed by a full training sequence on that index. Leaving
the DFS training modules enabled causes issues with the full
training done at resume. We also only needs these enabled
during a call to ddr_set_rate during runtime, so there's no
issue disabling them at the end of ddr_set_rate.
