This patch adds dependency rule generation and inclusion to the M0
Makefile, so that M0 objects will get correctly remade with an
incremental build if a header file they included changed.

The dependencies in the M0 Makefile are not correctly laid out, which
may lead to errors with make -j if the binary target gets evaluated
before the target that creates the directory. In addition, the M0
Makefile just calls mkdir without using the platform-independent macros
from the main ARM TF build system. This patch fixes those issues,
removes some unused (and broken) M0 build targets and merges the two M0
output directories into one (since there's no real point splitting it up
and it creates more hassle).

The default value of L2CTLR_DATA_RAM_LATENCY is 2, depends to
the test result on rk3399, the A72 will need lower voltage for
high frequency if it's set to be 5, and almost no effect on performance.

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.

This CL supports add M0 source code to built into the bl31.bin, the
goal is that we can load the M0 code binary into SRAM and execute it.
We need the M0 help us to clean the power_mode_en bit during the AP
PMU enter the state machine with interrupt, and avoid to the AP can
not exit the loop forever.

Add the common extra.ld.S and customized rk3399.ld.S to extend
to more features for different platforms.
For example, we can add SRAM section and specific address to
load there if we need it, and the common bl31.ld.S not need to
be modified.
Therefore, we can remove the unused codes which copying explicitly
from the function pmusram_prepare(). It looks like more clear.

The `toc_entry` and `image` data structures had a cyclic
relationship. This patch removes the explicit dependencies and introduces
functions to link them via the UUID.
This change highlights the intent of the code better and makes it more
flexible for future enhancements.

The values of CP15BEN, nTWI & nTWE bits in SCTLR_EL1 are architecturally
unknown if EL3 is AARCH64 whereas they reset to 1 if EL3 is AArch32. This
might be a compatibility break for legacy AArch32 normal world software if
these bits are not set to 1 when EL3 is AArch64. This patch enables the
CP15BEN, nTWI and nTWE bits in the SCTLR_EL1 if the lower non-secure EL is
AArch32. This unifies the SCTLR settings for lower non-secure EL in AArch32
mode for both AArch64 and AArch32 builds of Trusted Firmware.

In order to quantify the overall time spent in the PSCI software
implementation, an initial collection of PMF instrumentation points
has been added.
Instrumentation has been added to the following code paths:
- Entry to PSCI SMC handler. The timestamp is captured as early
as possible during the runtime exception and stored in memory
before entering the PSCI SMC handler.
- Exit from PSCI SMC handler. The timestamp is captured after
normal return from the PSCI SMC handler or if a low power state
was requested it is captured in the bl31 warm boot path before
return to normal world.
- Entry to low power state. The timestamp is captured before entry
to a low power state which implies either standby or power down.
As these power states are mutually exclusive, only one timestamp
is defined to describe both. It is possible to differentiate between
the two power states using the PSCI STAT interface.
- Exit from low power state. The timestamp is captured after a standby
or power up operation has completed.
To calculate the number of cycles spent running code in Trusted Firmware
one can perform the following calculation:
(exit_psci - enter_psci) - (exit_low_pwr - enter_low_pwr).
The resulting number of cycles can be converted to time given the
frequency of the counter.

The user guide incorrectly claimed that it is possible to load a
bootwrapped kernel over JTAG on Juno in the same manner as an EL3
payload. In the EL3 payload boot flow, some of the platform
initialisations in BL2 are modified. In particular, the TZC settings
are modified to allow unrestricted access to DRAM. This in turn allows
the debugger to access the DRAM and therefore to load the image there.
In the BL33-preloaded boot flow though, BL2 uses the default TZC
programming, which prevent access to most of the DRAM from secure state.
When execution reaches the SPIN_ON_BL1_EXIT loop, the MMU is disabled
and thus DS-5 presumably issues secure access transactions while trying
to load the image, which fails.
One way around it is to stop execution at the end of BL2 instead. At
this point, the MMU is still enabled and the DRAM is mapped as
non-secure memory. Therefore, the debugger is allowed to access this
memory in this context and to sucessfully load the bootwrapped kernel in
DRAM. The user guide is updated to suggest this alternative method.

This patch adds necessary updates for building and running Trusted
Firmware for AArch32 to user-guide.md. The instructions for running
on both `FVP_Base_AEMv8A-AEMv8A` in AArch32 mode and
`FVP_Base_Cortex-A32x4` models are added. The device tree files for
AArch32 Linux kernel are also added in the `fdts` folder.

The `fvp-base-gicv3-psci` and `fvp-foundation-gicv3-psci` device tree source
files did not have psci node entries for `system off` and `system reset`.
Also the DTS files included `rtsm_ve-motherboard-no_psci.dtsi` instead of
`rtsm_ve-motherboard.dtsi`. As a result, the Linux kernel failed to invoke
the PSCI_SYSTEM_OFF/RESET API when being shutdown/reset. This patch corrects
this problem and also updates the corresponding DTB files.
This patch also removes `rtsm_ve-motherboard-no_psci.dtsi` and
`fvp-foundation-motherboard-no_psci.dtsi` files as they are no longer used.
