The BSEC (Boot and Security and OTP control) is intended to control an OTP
(one time programmable) fuse box, used for on-chip non-volatile storage
for device configuration and security parameters.

rpi3: fix RPI3_PRELOADED_DTB_BASE usage

Add i.MX8 SoC SRTC/cpu-freq SIP runtime service support

Tegra downstream rebase 1.3.19

On i.MX8QM/i.MX8QX with system controller inside, the CPU's clock
rate is managed by SCFW(system controller firmware) and can ONLY be
changed from secure world, so SIP runtime service is needed for
setting CPU's clock rate, this patch adds cpu-freq SIP runtime service
support.
Signed-off-by: Anson Huang <Anson.Huang@nxp.com>

On i.MX8QM/i.MX8QX with system controller inside, the SRTC is
managed by SCFW(system controller firmware) and some functions
like setting SRTC's time etc. can ONLY be requested from secure
world, so SIP runtime service is needed for such kind of operations,
this patch adds SRTC SIP runtime service support for i.MX8QM and
i.MX8QX.

NXP's i.MX8 SoCs have system controller (M4 core) which takes
control of timer management, including watchdog, srtc and system
counter etc., other clusters like Cortex-A35 can send out command
via MU (Message Unit) to system controller for timer operation.

This patch adds timer IPC(inter-processor communication) support.

In case if `RPI3_PRELOADED_DTB_BASE` isn't defined explicitly with
proper pre-loaded DTB address, `add_define` macro defined in
`make_helpers/build_macros.mk` still supplies this definition to the
compiler like `-DRPI3_PRELOADED_DTB_BASE`, and it's obviously is set to
default value 1.

This simply leads to the wrong `MAP_NS_DTB` region definition (base_va
is set `0x1` instead of `0x00010000`) in `plat/rpi3/rpi3_common.c`:

Which causes aligment check to fail in `mmap_add_region_check()`:
VERBOSE: base_pa: 0x00000001, base_va: 0x00000001, size: 0x00010000

This patch skips the BTB invalidate workaround for Tegra210-B01 chips, as
they have already been fixed in the hardware. To allow the .S file to
include macros, add proper guards to tegra_platform.h.

This patch memmaps all the IRAM memory banks during boot. The BPMP
firmware might place the channels in any of the IRAMs, so it is better
to map all the banks to avoid surprises.

DRBG must be initialized to guarantee SRK has a random

an SRK on boot and during resume for SE1 and SE2. This SRK
value is not saved to PMC scratch, and should be overwitten

This patch adds the driver to communicate with the BPMP processor
for power management use cases. BPMP controls the entry into cluster
and system power states. The Tegra210 platform port queries the BPMP
to calculate the target state for the cluster. In case BPMP does not
allow CCx entry, the core enters a power down state.
