TBB: Add an IO abstraction layer to load encrypted firmwares ...

TBBR spec advocates for optional encryption of firmwares (see optional
requirement: R060_TBBR_FUNCTION). So add an IO abstaction layer to
support firmware decryption that can be stacked above any underlying IO/
packaging layer like FIP etc. It aims to provide a framework to load any
encrypted IO payload.

Also, add plat_get_enc_key_info() to be implemented in a platform
specific manner as handling of encryption key may vary from one platform
to another.

imx: console: Use CONSOLE_T_BASE for UART base address ...

Since commit ac71344e9eca we have the UART base address in the generic
console_t structure. For most platforms the platform-specific struct
console is gone, so we *must* use the embedded base address, since there
is no storage behind the generic console_t anymore.

Replace the usage of CONSOLE_T_DRVDATA with CONSOLE_T_BASE to fix this.

Tegra: spe: use CONSOLE_T_BASE to save MMIO base address ...

Commit ac71344 moved the base address
for the MMIO aperture of the console inside the console_t struct. As
a result, the driver should now save the MMIO base address to console_t
at offset marked by the CONSOLE_T_BASE macro.

This patch updates the SPE console driver to use the CONSOLE_T_BASE macro
to save/access the MMIO base address.

SPMD: loading Secure Partition payloads ...

This patch implements loading of Secure Partition packages using
existing framework of loading other bl images.

The current framework uses a statically defined array to store all the
possible image types and at run time generates a link list and traverse
through it to load different images.

To load SPs, a new array of fixed size is introduced which will be
dynamically populated based on number of SPs available in the system
and it will be appended to the loadable images list.

to service both EL1 and EL2 as opposed to serving only EL1.

fvp: add Cactus/Ivy Secure Partition information ...

Add load address and UUID in fw config dts for Cactus and Ivy which are
example SP's in tf-test repository.

For prototype purpose these information is added manually but later on
it will be updated at compile time from SP layout file and SP manifests
provided by platform.

fconf: Add Secure Partitions information as property ...

Use the firmware configuration framework to retrieve information about
Secure Partitions to facilitate loading them into memory.

To load a SP image we need UUID look-up into FIP and the load address
where it needs to be loaded in memory.

This patch introduces a SP populator function which gets UUID and load
address from firmware config device tree and updates its C data
structure.

uniphier: prepare uniphier_soc_info() for next SoC ...

The revision register address will be changed in the next SoC.

The LSI revision is needed in order to know where the revision
register is located, but you need to read out the revision
register for that. This is impossible.

We need to know the revision register address by other means.
Use BL_CODE_BASE, where the base address of the TF image that is
currently running. If it is bigger than 0x80000000 (i.e. the DRAM
base is 0x80000000), we assume it is a legacy SoC.
