2021-04-06arm: meson: remove static ethernet link setupNeil Armstrong1-22/+0
The static ethernet link type config code is no more needed because now handled by the meson8b glue driver, delete it. Signed-off-by: Neil Armstrong <narmstrong@baylibre.com>

Move this uncommon header out of the common header. Signed-off-by: Simon Glass <sjg@chromium.org>
2018-11-26ARM: meson: Add boot device discoveryNeil Armstrong1-0/+1
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.

2018-11-26ARM: meson: Add support for AXG familyNeil Armstrong1-0/+51
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 Signed-off-by: Jerome Brunet <jbrunet@baylibre.com> Signed-off-by: Neil Armstrong <narmstrong@baylibre.com>
