meson/gxl: Add support for SHA256 DMA engine

In order to configure and boot SCP, BL31 has to compute and send
the SHA-256 of the firmware data via scpi. Luckily Amlogic GXL SOC
has a DMA facility that could be used to offload SHA-256
computations. This adds basic support of this hardware SHA-256

meson/gxl: Initial port of Amlogic Meson S905x (GXL)

The Amlogic Meson S905x is a SoC with a quad core Arm Cortex-A53 running
at 1.5Ghz. It also contains a Cortex-M3 used as SCP.

This port is a minimal implementation of BL31 capable of booting
mainline U-Boot and Linux:

- Partial SCPI support.
- Basic PSCI support (CPU_ON, SYSTEM_RESET, SYSTEM_OFF).
- GICv2 driver set up.
- Basic SIP services (read efuse data, enable/disable JTAG).

This port has been tested on a lepotato.

rockchip: add an fdt parsing stub for platform param

While Coreboot does submit the list of linked parameter structs as

This results in current ATF not running at all when started from U-Boot.

To fix this, add a stub that checks if the parameter is a fdt so we

Sandrine Bailleux [Wed, 13 Mar 2019 17:02:09 +0000 (18:02 +0100)]
Put Pointer Authentication key value in BSS section

The dummy implementation of the plat_init_apiakey() platform API uses
an internal 128-bit buffer to store the initial key value used for
Pointer Authentication support.

The intent - as stated in the file comments - was for this buffer to
be write-protected by the MMU. Initialization of the buffer would be
performed before enabling the MMU, thus bypassing write protection
checks.

However, the key buffer ended up into its own read-write section by
mistake due to a typo on the section name ('rodata.apiakey' instead of
'.rodata.apiakey', note the leading dot). As a result, the linker
script was not pulling it into the .rodata output section.

One way to address this issue could have been to fix the section
name. However, this approach does not work well for BL1. Being the
first image in the boot flow, it typically is sitting in real ROM
so we don't have the capacity to update the key buffer at any time.

The dummy implementation of plat_init_apiakey() provided at the moment
is just there to demonstrate the Pointer Authentication feature in
action. Proper key management and key generation would have to be a
lot more careful on a production system.

Therefore, the approach chosen here to leave the key buffer in
writable memory but move it to the BSS section. This does mean that
the key buffer could be maliciously updated for intalling unintended
keys on the warm boot path but at the feature is only at an
experimental stage right now, this is deemed acceptable.

Rename it to "PLAT_MHUV2_BASE", so that platforms other than arm
can use generic MHU doorbell driver.

plat/synquacer: enable SCMI support

Enable the SCMI protocol support in SynQuacer platform.
Aside from power domain, system power and apcore management protocol,
this commit adds the vendor specific protocol(0x80).
This vendor specific protocol is used to get the dram mapping information

Makefile: fix linking with pie and binutils > 2.27

Since binutils 1a9ccd70f9a7[1] TFA will not link when the PIE option is
used:

    aarch64-linux-gnu-ld: build/fvp/debug/bl31/bl31.elf: Not enough room
        for program headers, try linking with -N
    aarch64-linux-gnu-ld: final link failed: Bad value

This issue was also encountered by u-boot[2] and linux powerpc kernel
[3]. The fix is to provide --no-dynamic-linker for the linker. This
tells the linker that PIE does not need loaded program program headers.
