NOTE: __ASSEMBLY__ macro is now deprecated in favor of __ASSEMBLER__.

All common C compilers predefine a macro called __ASSEMBLER__ when
preprocessing a .S file. There is no reason for TF-A to define it's own
__ASSEMBLY__ macro for this purpose instead. To unify code with the
export headers (which use __ASSEMBLER__ to avoid one extra dependency),
let's deprecate __ASSEMBLY__ and switch the code base over to the
predefined standard.

px30 is a Quad-core soc and Cortex-a53 inside.
This patch supports the following functions:
1. basic platform setup
2. power up/off cpus
3. suspend/resume cpus
4. suspend/resume system
5. reset system
6. power off system

The current code doing power-management from sram is highly
arm64-specific so should live in a corresponding subdirectory
and not in the common area.

- Migrate to new GIC interfaces.
- Migrate to bl31_early_platform_setup2().
- Use bl31_warm_entrypoint() instead of psci_entrypoint().
- Use PLAT_VIRT_ADDR_SPACE_SIZE and PLAT_PHY_ADDR_SPACE_SIZE.
- Update Makefile paths.
- Remove references to removed build options.
- Use private definition of bl31_params_t.

These directives are only used when stabs debugging information
is used, but we use ELF which uses DWARF debugging information.
Clang assembler doesn't support these directives, and removing
them makes the code more compatible with clang.

when logic power rail shutdown, CRU register will back to reset
value, ddr use abpll as clock source when do suspend, we need to save
and dpll value in pmusram, then set back these ddr clock back to dpll
when dddr resume.

unlike rk3399 and rk3368, there are some rockchip 64bit SOC
do not have CPUPD, and pmu_cpuson_entrypoint() is common
function for rockchip platform, so we need to check wakeup
cpu when resume.

with PMU_PERILP_PD_EN bit enable, the soc will shutdown
cm0, crypto, dcf, imem(normal SRAM), dmac, bootrom, efuse_con,
spi, i2c, uart, saradc, tsadc when suspend, we have M0 code
need to run when suspend in normal SRAM, so we need to take
care of that.

we just copy bin file to pmusram before, now we add pmusram section

We used dcf do ddr frequency scaling, but we just include a dcf
binary, it hard to maintain later, we have M0 compile flow in ATF,
and M0 can also work for ddr frequency scaling, so let's use it.

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.

Sometimes this will cause the long delay for suspend/resume.
Since the 24M OCS will be turned off in power mode.
Also, remove the ERROR_DEPRECATED config define.

1. Remove the AP_PWROFF in ATF, should configure it in kernel.
2. Save and restore the PWMs pin/regs for suspend/resume.
3. The pmusgrf reset-hold bits needs to be released. since the
   pmusgrf reset-hold bits needs to be held.
4. Configure the PMU power up/down cycles about delay 3ms.
5. With the MMIO register block as one big mapping.
6. Fix the build error with psci_entrypoint since PSCI lib updated.

Fixes the commit
9ec78bdf ("rockchip: support the suspend/resume for rk3399").

This patch adds to support the RK3368 and RK3399 SoCs.

RK3368/RK3399 is one of the Rockchip family SoCs, which is an
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.
