- Why I did it
Add support for mellanox platform building for target architecture arm64.
- How I did it
Contains the following changes:
1. Change instances of hard-coded amd64 to $(CONFIGURED_ARCH)
2. Add logic to download correct binary for MFT package
3. Add TARGET_BOOTLOADER=grub definition to rules.mk to override default arm64 bootloader
- How to verify it
Build mellanox platform with TARGET_ARCH set as arm64
Adjust the SDK makefiles so that it reflects the dependencies among libraries in SDK 4.3.2104.
This is a supplement of PR [Mellanox]Update SDK(4.3.2104), SAI-Implementation(1.15) and firmware 2162. It doesn't impact the sonic-mellanox.bin image but makes the future SDK-integration easier.
