0cc53faf59 arm: meson: board-gx: Setup VPU in fdt
If VIDEO_MESON is enabled, we need to setup the fdt for the framebuffer.

Call meson_vpu_rsv_fb() which reserves the framebuffer memory region for
EFI, and sets up simple-framebuffer nodes if simplefb support is
enabled.

d96a782d09 ARM: meson: Add boot device discovery
The Amlogic Meson SoCs ROM supports a boot over USB with a custom protocol.

When no other boot medium are available (or by forcing the USB mode), the
ROM sets the primary USB port as device mode and waits for a Host to
enumerate.

When enumerated, a custom protocol described at [1] permits writing to
memory and execute some specific FIP init code to run the loaded
Arm Trusted Firmware BL2 and BL3 stages before running the BL33 stage.

In this mode, we can load different binaries that can be used by U-boot
like a script image file.

This adds support for a custom USB boot stage only available when the
boot mode is USB and the script file at a pre-defined address is valid.
This support was heavily copied from the Sunxi Allwinner FEL U-Boot support.

The tool pyamlboot described at [2], permits using this boot mode on boards
exposing the first USB port, either as OTG or Host port.

485bba395e ARM: meson: Add support for AXG family
This patch adds support for the Amlogic AXG SoC, which is very close from
the Amlogic GXL SoCs with :
- Same 4xCortex-A53 CPUs but clocked at 1.2GHZ max
- DDR Interface limited to DDR4 16bit
- The whole physical register address space has been moved to 0xfxxxxxxx
- The pinctrl setup has changed
- The clock tree is different enough to use a different driver

96a739b460 ARM: rework amlogic configuration
Rework the board SYS_BOARD, SYS_VENDOR and SYS_CONFIG_NAME setup by moving
the board Kconfig into the mach-meson Kconfig to make it easier to add
new boards for a SoC architecture and add a custom config header or custom

This drops the board CONFIGs and the duplicate boards configs headers in
favor of a single meson64.h config header.

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

c7be3e5a79 ARM: arch-meson: build memory banks using reported memory from registers
As discussed at [1], the Amlogic Meson GX SoCs can embed a BL31 firmware
and a secondary BL32 firmware.
Since mid-2017, the reserved memory address of the BL31 firmware was moved
and grown for security reasons.

But mainline U-Boot and Linux has the old address and size fixed.

These SoCs have a register interface to get the two firmware reserved
memory start and sizes.

This patch adds a dynamic reservation of the memory zones in the device tree bootmem
reserved memory zone used by the kernel in early boot.
To be complete, the memory zones are also added to the EFI reserved zones.

Depends on patchset "Add support for Amlogic GXL Based SBCs" at [2].

- reduced preprocessor load
- kept Odroid-C2 static memory mapping as exception
