well, let's use that generic location and drop the UART driver specific
data structure at all.

The implementation of the heap function plat_get_mbedtls_heap() becomes
mandatory for platforms supporting TRUSTED_BOARD_BOOT.
The shared Mbed TLS heap default weak function implementation is
converted to a helper function get_mbedtls_heap_helper() which can be
used by the platforms for their own function implementation.

This patch defines the expected DTB overlay address in the memory map for
this platform. Its important that all points in the boot process agree on
this memory map even if not all elements utilize it.

Recently upstreamed changes to OP-TEE mean that it is possible for OP-TEE
to provide a DTB overlay directly to subsequent boot stages thus negating
the requirement to bundle a DTB in the FIP.
This patch switches off the dependency on the DTB in the FIP descriptor
instead we will provide the necessary data as an overlay from OP-TEE.

Enforce full include path for includes. Deprecate old paths.
The following folders inside include/lib have been left unchanged:
- include/lib/cpus/${ARCH}
- include/lib/el3_runtime/${ARCH}
The reason for this change is that having a global namespace for
includes isn't a good idea. It defeats one of the advantages of having
folders and it introduces problems that are sometimes subtle (because
you may not know the header you are actually including if there are two
of them).
For example, this patch had to be created because two headers were
called the same way: e0ea0928d5 ("Fix gpio includes of mt8173 platform
to avoid collision."). More recently, this patch has had similar
problems: 46f9b2c3a2 ("drivers: add tzc380 support").
This problem was introduced in commit 4ecca33988 ("Move include and
source files to logical locations"). At that time, there weren't too
many headers so it wasn't a real issue. However, time has shown that
this creates problems.
Platforms that want to preserve the way they include headers may add the
removed paths to PLAT_INCLUDES, but this is discouraged.

All identifiers, regardless of use, that start with two underscores are
reserved. This means they can't be used in header guards.
The style that this project is now to use the full name of the file in
capital letters followed by 'H'. For example, for a file called
"uart_example.h", the header guard is UART_EXAMPLE_H.
The exceptions are files that are imported from other projects:
- CryptoCell driver
- dt-bindings folders
- zlib headers

Even though at this point plat_crash_console_flush is optional, it will
stop being optional in a following patch.
The console driver of warp7 doesn't support flush, so the implementation
is a placeholder.
TI had ``plat_crash_console_init`` and ``plat_crash_console_putc``, but
they weren't global so they weren't actually used. Also, they were
calling the wrong functions.
imx8_helpers.S only has placeholders for all of the functions.

Previous changes in this series made the necessary driver additions and
updates. With those changes in-place we can add the platform.mk and
bl2_el3_setup.c to drive the boot process.
After this commit its possible to build a fully-functional TF-A for the
WaRP7 and boot from the BootROM to the Linux command prompt in secure or
non-secure mode.

This patch adds a callback into the BootROM's provided High Assurance Boot
(HAB) failsafe function when panicking i.e. the call is done without making
use of stack.
The HAB failsafe function allows a piece of software to call into the
BootROM and place the processor into failsafe mode.
Failsafe mode is a special mode which presents a serial download protocol
interface over UART or USB at the time of writing.
If the board has been set into secure mode, then only a signed binary can
be used to recover the board.
Thus failsafe gives a putatively secure method of performing a secure
recovery over UART or USB.

This patch adds entries to the mem params array for
- BL32
- BL32_EXTRA1
- BL32_EXTRA2
- BL33
- HW_CONFIG_ID
BL32 is marked as bootable to indicate that OPTEE is the thing that should
be booted next.
In our model OPTEE chain-loads onto u-boot so only BL32 is bootable.

In order to enable compile time differences in HAB interaction, we should
split out the definition of the base address of the HAB API.
Some version of the i.MX series have different offsets from the BootROM
base for the HAB callback table.
This patch defines the header into which we will define the i.MX7 specific
offset. The offset of the i.MX7 function-callback table is simultaneously
defined.
Once done, we can latch a set of common function pointer locations from the
offset given here and if necessary change the offset for different
processors without any other code-change.
For now all we support is i.MX7 so the only offset being defined is that
for the i.MX7.

In order to have some common code shared between similar SOCs its pretty
common to have IP blocks reused. In reusing those blocks we frequently need
to map compatible blocks to different addresses depending on the SOC.
This patch adds a basic memory map of the i.MX7 based on the "Cortex-A7
Memory Map" section 2.12 of "i.MX7Solo Applications Processor Reference
Manual, Rev 0.1 08/2016"
In memory map terms the i.MX7S and i.MX7D are identical with the D
variant containing two Cortex-A7 cores plus a Cortex-M core and the S
variant containing one Cortex-A7 and one Cortex-M.
