The PLAT_XLAT_TABLES_DYNAMIC build option, defined in platform_def.h
in Arm platforms, is checked by several headers, affecting their
behaviour. To avoid issues around the include ordering of the headers,
the definition should be moved to the platform's makefile.

Use full include paths like it is done for common includes.

This cleanup was started in commit d40e0e08283a ("Sanitise includes
across codebase"), but it only cleaned common files and drivers. This
patch does the same to Arm platforms.

plat/arm: Save BL2 descriptors to reserved memory.

spd: trusty: trusty_setup should bail on unknown image

Add more SIP runtime service for i.MX8

ti: k3: common: Add support for runtime detection of GICR base address

Enable necessary A53 erratas for i.MX8QM and i.MX8MQ

Tf2.0 tegra downstream rebase 1.22.19

When an unknown Trusty image is found, there's no point of still trying
to register the BL32 init handler. Instead, we just should bail out of
the trusty_setup() and allow the system to continue to boot.

This patch adds a platform setup handler that gets called after
the MMU is enabled. Platforms wanting to make use of this handler
should declare 'plat_late_platform_setup' handler in their platform
files, to override the default weakly defined handler.

There are Tegra platforms which have limited UART ports and so
all the components have to share the console. The SPE helps out
by collecting all the logs in such cases and prints them on the
shared UART port.

This patch adds a driver to communicate with the SPE driver, which
in turn provides the console.

makefiles and removes it from tegra_common.mk. This allows future

This patch adds support to save the system suspend entry and exit
markers to TZDRAM to help the trampoline code decide if the current
warmboot is actually an exit from System Suspend.

The Tegra186 platform handler sets the system suspend entry marker
before entering SC7 state and the trampoline flips the state back to
system resume, on exiting SC7.

This patch adds a helper function to get the SMMU context's offset
and uses another helper function to get the CPU trampoline offset.
These helper functions are used by the System Suspend entry sequence
to save the SMMU context and CPU reset handler to TZDRAM.

This patch renames all the secure scratch registers to reflect their
usage.

This is a list of all the macros being renamed:

- SECURE_SCRATCH_RSV1_* -> SCRATCH_RESET_VECTOR_*
- SECURE_SCRATCH_RSV6 -> SCRATCH_SECURE_BOOTP_FCFG
- SECURE_SCRATCH_RSV11_* -> SCRATCH_SMMU_TABLE_ADDR_*
- SECURE_SCRATCH_RSV53_* -> SCRATCH_BOOT_PARAMS_ADDR_*
- SECURE_SCRATCH_RSV55_* -> SCRATCH_TZDRAM_ADDR_*

NOTE: Future SoCs will have to define these macros to
      keep the drivers functioning.

This patch adds the driver to communicate with the BPMP firmware on Tegra
SoCs, starting Tegra186. BPMP firmware is responsible for clock enable/
disable requests, module resets among other things.

MRQ is short for Message ReQuest. This is the general purpose, multi channel
messaging protocol that is widely used to communicate with BPMP. This is further
divided into a common high level protocol and a peer-specific low level protocol.
The higher level protocol specifies the peer identification, channel definition
and allocation, message structure, message semantics and message dispatch process
whereas the lower level protocol defines actual message transfer implementation
details. Currently, BPMP supports two lower level protocols - Token Mail Operations
(TMO), IVC Mail Operations (IMO).

This driver implements the IMO protocol. IMO is implemented using the IVC (Inter-VM
Communication) protocol which is a lockless, shared memory messaging queue management
protocol.

The IVC peer is expected to perform the following as part of establishing a connection
with BPMP.

1. Initialize the channels with tegra_ivc_init() or its equivalent.
2. Reset the channel with tegra_ivc_channel_reset. The peer should also ensure that
   BPMP is notified via the doorbell.
3. Poll until the channel connection is established [tegra_ivc_channel_notified() return
   0]. Interrupt BPMP with doorbell each time after tegra_ivc_channel_notified() return
   non zero.

The IPC driver currently supports reseting the GPCDMAand XUSB_PADCTL hardware blocks. In
future, more hardware blocks would be supported.
