Some OSes (e.g. Ubuntu 18.04 LTS on Raspberry Pi 3) may disable the runtime UART in a manner that prevents the system from rebooting if ATF tries to send runtime messages there. Also, we don't want the firmware to share the UART with normal world, as this can be a DoS attack vector into the secure world. This patch fixes these 2 issues by introducing new build option RPI3_RUNTIME_UART, that disables the runtime UART by default. Fixes ARM-software/tf-issues#647 Signed-off-by: Pete Batard <pete@akeo.ie>

When a device tree blob is present at a known address, instead of, for example, relying on the user modifying the Linux command line to warn about the memory reserved for the Trusted Firmware, pass it on the DTB. The current code deletes the memory reserved for the default bootstrap of the Raspberry Pi and adds the region used by the Trusted Firmware. This system replaces the previous one consisting on adding ``memmap=16M$256M`` to the Linux command line. It's also meant to be used by U-Boot and any other bootloader that understands DTB files.

The Raspberry Pi 3 port doesn't actually depend on any Arm platform code, so the dependencies can be removed. Change-Id: Ic2f47f5001bebde3862815b1d880a169d82b3f65 Signed-off-by: Antonio Nino Diaz <antonio.ninodiaz@arm.com>

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. Change-Id: I2b22e8933fad6a614588ace559f893e97329801f Signed-off-by: Antonio Nino Diaz <antonio.ninodiaz@arm.com>

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. Change-Id: I8b3adb61f5a5623716e0e8b6799404c68dd94c60 Signed-off-by: Antonio Nino Diaz <antonio.ninodiaz@arm.com>

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. Change-Id: I3229fbc080f5996cff47efce8e799bae94e0d5cb Signed-off-by: Antonio Nino Diaz <antonio.ninodiaz@arm.com>

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: https://github.com/raspberrypi/firmware/wiki Change-Id: I11943b99b52cc1409f4a195ebe58eb44ae5b1d6c Signed-off-by: Antonio Nino Diaz <antonio.ninodiaz@arm.com>

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. Change-Id: Id5b5b1b7b9f87767db63fd01180ddfea855a7207 Signed-off-by: Antonio Nino Diaz <antonio.ninodiaz@arm.com>

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. Tested-by: Antonio Nino Diaz <antonio.ninodiaz@arm.com> Signed-off-by: Ying-Chun Liu (PaulLiu) <paul.liu@linaro.org>

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.
