在网上搜索到了3B的UEFI，想着能不能把它完善下，里面显示对于acpi的支持是有限的，但是现在没有任何参考的情况下求教如何添加相关的支持，没有思路。
Hi hzhxhljy
For the UEFI/edk2 support in ARM architecture, there the open source project on different vendor platform, the project can be found from below:
https://github.com/tianocore/edk2-platforms
For example, it include below vendor and platforms:
## AMD* [Cello](Platform/LeMaker/CelloBoard)* [Overdrive](Platform/AMD/OverdriveBoard)* [Overdrive 1000](Platform/SoftIron/Overdrive1000Board)
## ARM* [Juno](Platform/ARM/JunoPkg)* [Versatile Express](Platform/ARM/VExpressPkg)
## Hisilicon* [D02](Platform/Hisilicon/D02)* [D03](Platform/Hisilicon/D03)* [D05](Platform/Hisilicon/D05)* [HiKey](Platform/Hisilicon/HiKey)
## Marvell* [Armada 70x0](Platform/Marvell/Armada)
In addition, there is some spec related with UEFI boot in ARM architecture as below:
Server Base Boot Requirements Specification(System Software on ARM® Platforms)

Hope these can help you development.
