feat(imx8m): detect console base address during runtime

Provide a helper to detect the enabled UART device during runtime. This
lower the integration effort and make it more straight forward for
'simple' use-cases with a single UART enabled. If multiple UARTs are
enabled the first enabled is returned.

The auto-detection is enabled by setting IMX_BOOT_UART_BASE=0 to keep
the backward compatibility. For more advanced use-cases (multiple UARTs
are enabled) the user still has to provide the correct base address.

refactor(build): distinguish BL2 as TF-A entry point and BL2 running at EL3

BL2_AT_EL3 is an overloaded macro which has two uses:
1. When BL2 is entry point into TF-A(no BL1)
2. When BL2 is running at EL3 exception level
These two scenarios are not exactly same even though first implicitly
means second to be true. To distinguish between these two use cases we
introduce new macros.
BL2_AT_EL3 is renamed to RESET_TO_BL2 to better convey both 1. and 2.
Additional macro BL2_RUNS_AT_EL3 is added to cover all scenarious where
BL2 runs at EL3 (including four world systems).

BREAKING CHANGE: BL2_AT_EL3 renamed to RESET_TO_BL2 across the
repository.

Enable PIE support so the BL31 firmware can be loaded from anywhere

need to enable it by setting ENABLE_PIE := 1.

Introduce support for High Assurance Boot (HABv4), which is used to
establish and extend the Root-of-Trust during FW loading at any given

This commit introduces support for HAB ROM Vector Table (RVT) API, which
is normally used by post-ROM code to authenticate additional boot images
(Kernel, FDT, FIT, etc.) that are taking part in the Root-of-Trust.

feat(imx8mm): add hab and map required memory blocks

In order for HAB to perform operations, memory regions has to be mapped
in TF-A, which HAB ROM code would use internally.

Include those memory blocks for i.MX8MM SoC. Of a special note, the DRAM
block is mapped with complete size available on the platform and uses
MT_RW attributes, this is required to minimize the size of translation
tables and provide a possibility to exchange the execution results
between EL3 and EL1&2, see details in [1].

fix(imx8m): move caam init after serial init

CAAM provides serial output during initialization, but the serial init
occurs after CAAM. This leads to serial output produced by CAAM init
function to be omitted and not displayed.

Change the order of initialization and call CAAM init after Serial. This
has no impact as Serial does not require CAAM to be initialized upfront.

fix: make TF-A use provided OpenSSL binary

Currently Tf-A uses whatever openssl binary is on the system to sign
images. However if OPENSSL_DIR is specified in the build flags this can
lead to linking issues as the system binary can end up being linked
against shared libraries provided in OPENSSL_DIR/lib if both binaries
(the system's and the on in OPENSSL_DIR/bin) are the same version.
This patch ensures that the binary used is always the one given by
OPENSSL_DIR to avoid those link issues.
