[PATCH v2 3/3] arm: mvebu: Add Allied Telesis x220
Chris Packham

Thu Dec 18 20:42:18 CET 2025
Add the Allied Telesis x220 board. There are a number of other variants
with the same CPU block that are sold under some different brand names
but the x220 was first.
The x220 uses the AlleyCat3 switch chip with integrated ARMv7 CPU.
Because of this it is reliant on a binary blob for the DDR training. In
upstream u-boot this is replaced by an empty file.
