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

These directives are only used when stabs debugging information

Clang assembler doesn't support these directives, and removing

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.

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.

This patch changes all Rockchip platforms to use the new
MULTI_CONSOLE_API. The platform-specific plat_crash_console
implementations are removed so that the platform can use the ones from
the common platform code instead.
Also change the registers used in plat_crash_print_regs. The existing
use of x16 and x17 has always been illegal, since those registers are
reserved for use by the linker as a temporary scratch registers in
intra-procedure-call veneers and can never be expected to maintain their
values across a function call.

When defining different sections in linker scripts it is needed to align
them to multiples of the page size. In most linker scripts this is done
by aligning to the hardcoded value 4096 instead of PAGE_SIZE.
This may be confusing when taking a look at all the codebase, as 4096
is used in some parts that aren't meant to be a multiple of the page
size.

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.

For rk3399, the L2ACTLR[14] is 0 by default, as ACE CCI-500 doesn't
support WriteEvict. and you will hit the condition L2ACTLR[3] with 0,
as the Evict transactions should propagate to CCI-500 since it has
snoop filters.
Maybe this erratum applies to all Cortex-A53 cores so far, especially
if RK3399's A53 is a r0p4. we should enable it to avoid data corruption,
