Secure FLASH0 memory map looks like:
- Offset: 0 to 256K -> bl1.bin
- Offset: 256K to 4.25M -> fip.bin

FLASH1 is normally used via UEFI/edk2 to keep varstore.

Following build flags have been added to support optional firmware
encryption:

- FW_ENC_STATUS: Top level firmware's encryption numeric flag, values:
    0: Encryption is done with Secret Symmetric Key (SSK) which is
       common for a class of devices.
    1: Encryption is done with Binding Secret Symmetric Key (BSSK) which
       is unique per device.

- ENC_KEY: A 32-byte (256-bit) symmetric key in hex string format. It
    could be SSK or BSSK depending on FW_ENC_STATUS flag.

- ENC_NONCE: A 12-byte (96-bit) encryption nonce or Initialization Vector
    (IV) in hex string format.

- ENCRYPT_BL31: Binary flag to enable encryption of BL31 firmware.

- ENCRYPT_BL32: Binary flag to enable encryption of Secure BL32 payload.

Similar flags can be added to encrypt other firmwares as well depending
on use-cases.

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
  Tegra: spe: use CONSOLE_T_BASE to save MMIO base address

Since commit ac71344e

 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.

Commit ac71344e

 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.

* changes:
  SPMD: loading Secure Partition payloads
  fvp: add Cactus/Ivy Secure Partition information
  fconf: Add Secure Partitions information as property

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.

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.

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.
