#### Why I did it
Facilitate Automatic integration of sdk kernel patches into SONiC.
**Inputs to the Script:**
1) `MLNX_SDK_VERSION` Eg: `4.5.4206`
2) `MLNX_SDK_ISSU_VERSION` Eg: `101`
**Note: If nothing is provided the one already present in the sdk.mk file is used**
3) `MLNX_SDK_SOURCE_BASE_URL:`
**Note: If nothing is provided the upstream sdk drivers url is used**
4) `CREATE_BRANCH: (y|n)` Creates a branch instead of a commit (optional, default: n)
5) `BRANCH_SONIC`: Only relevant when CREATE_BRANCH is y. `Default: master`.
Note: These should be provided through `SONIC_OVERRIDE_BUILD_VARS ` parameter
**Output:**
1) Script creates a commit in sonic-linux-kernel with any updates to sdk-kernel patches in sonic in accordance with the version provided by `MLNX_SDK_VERSION`
**Note: Script Doesn't commit anything to linux-kernel when there aren't any changes required..**
#### How I did it
1) Added a new make target which can be invoked by calling `make integrate-mlnx-sdk`
```
user@server:/sonic-buildimage/src/sonic-linux-kernel$ git rev-parse --abbrev-ref HEAD
master_6f38dca_integrate_4.5.4206
user@server:/sonic-buildimage/src/sonic-linux-kernel$ git log --oneline -n 1
d64d1e7 (HEAD -> master_6f38dca_integrate_4.5.4206) Intgerate MLNX SDK 4.5.4206 Kernel Patches
```
Changes made will be summarized under `sonic-buildimage/integrate-mlnx-sdk_user.out` file. Debugging and troubleshooting output is written to `sonic-buildimage/integrate-mlnx-sdk.log` files

#### Limitations:
1) Assumes that the sdk kernel patches are always upstreamed
#### How to verify it
Build the Kernel and test
- Why I did it
To optimize Mellanox platform build
- How I did it
sdk debs are now downloaded as Spectrum-SDK-Drivers-SONiC-Bins release
sx kernel is downloaded as zip from Spectrum-SDK-Drivers
- How to verify it
configure/build for Mellanox platform
Signed-off-by: Yakiv Huryk <yhuryk@nvidia.com>
- 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
