This option allows the Trusted Firmware to pass the correct arguments to
a 32 or 64-bit Linux kernel without the need of an intermediate loader
such as U-Boot.

It uses the hardware RNG in a similar way as Juno (it gets 128 bits of
entropy and does xor on them).

It is disabled by default.

There is no way to boot BL31 at the addresses specified in the platform
memory map unless an extra loader is used at address 0x00000000. It is
better to remove it to prevent confusion. Having it enabled was a bug.

Implement VideoCore mailbox interface driver and use it to get the board
revision identifier.

For now it is only used to print the model for debug purposes.

This wiki contains the documentation of the mailbox interface:

Add a new default makefile target to concatenate BL1 and the FIP and
generate armstub8.bin. This way it isn't needed to do it manually.

Documentation updated to reflect the changes.

This patch adds support for TBB to rpi3. The ROTPK is generated at build
time and is included into BL1/BL2. The key and content certificates are
read over semihosting.

Support for loading optee images as BL32 secure payload.

Switch to the new console APIs enabled by setting MULTI_CONSOLE_API=1.

The crash console doesn't use this API, it uses internally the core
functions of the 16550 console.

`bl31_plat_runtime_setup` is no longer needed. When this platform port
was introduced, that function used to disable the console. It was needed
to override that behaviour. The new behaviour is to switch to the
runtime console. The console is registered for all scopes (boot, crash
and runtime) in `rpi3_console_init` so it is not needed to override the
default behaviour anymore.

Update documentation.

This port can be compiled to boot an AArch64 or AArch32 payload with the
build option `RPI3_BL33_AARCH32`.

Note: This is not a secure port of the Trusted Firmware. This port is
only meant to be a reference implementation to experiment with an
inexpensive board in real hardware.
