- What I did
Added support for secure upgrade.
- How I did it
During sonic_installer install, added secure upgrade image verification.
HLD can be found in the following PR: sonic-net/SONiC#1024
- Why I did it
Feature is used to allow image was not modified since built from vendor. During installation, image can be verified with a signature attached to it.
- How I did it
Feature includes image signing during build (in sonic buildimage repo) and verification during image install (in sonic-utilities).
- How to verify it
In order for image verification - image must be signed - need to provide signing key and certificate (paths in SECURE_UPGRADE_DEV_SIGNING_KEY and SECURE_UPGRADE_DEV_SIGNING_CERT in rules/config) during build , and during image install, need to enable secure boot flag in bios, and signing_certificate should be available in bios.
- Feature dependencies
In order for this feature to work smoothly, need to have secure boot feature implemented as well.
The Secure boot feature will be merged in the near future.
Refactors the SONiC Installer to support greater flexibility in building for a given architecture and bootloader.
#### Why I did it
Currently the SONiC installer assumes that if a platform is ARM based that it uses the `uboot` bootloader and uses the `grub` bootloader otherwise. This is not a correct assumption to make as ARM is not strictly tied to uboot and x86 is not strictly tied to grub.
#### How I did it
To implement this I introduce the following changes:
* Remove the different arch folders from the `installer/` directory
* Merge the generic components of the ARM and x86 installer into `installer/installer.sh`
* Refactor x86 + grub specific functions into `installer/default_platform.conf`
* Modify installer to call `default_platform.conf` file and also call `platform/[platform]/patform.conf` file as well to override as needed
* Update references to the installer in the `build_image.sh` script
* Add `TARGET_BOOTLOADER` variable that is by default `uboot` for ARM devices and `grub` for x86 unless overridden in `platform/[platform]/rules.mk`
* Update bootloader logic in `build_debian.sh` to be based on `TARGET_BOOTLOADER` instead of `TARGET_ARCH` and to reference the grub package in a generic manner
#### How to verify it
This has been tested on a ARM test platform as well as on Mellanox amd64 switches as well to ensure there was no impact.

Introduce new sonic-buildimage images for Broadcom DNX ASIC family.
sonic-broadcom-dnx.bin
sonic-aboot-broadcom-dnx.swi
How I did it
NO CHANGE to existing make commands
make init; make configure PLATFORM=broadcom; make target/sonic-aboot-broadcom.swi; make target/sonic-broadcom.bin
The difference now is that it will result in new broadcom images for DNX asic family as well.
sonic-broadcom.bin, sonic-broadcom-dnx.bin
sonic-aboot-broadcom.swi, sonic-aboot-broadcom-dnx.swi
Note: This PR also adds support for Broadcom SAI 5.0 (based on 1.8 SAI ) for DNX based platform + changes in platform x86_64-arista_7280cr3_32p4 bcm config files and platform_env.conf files
ARM Architecture support in SONIC
make configure platform=[ASIC_VENDOR_ARCH] PLATFORM_ARCH=[ARM_ARCH]
SONIC_ARCH: default amd64
armhf - arm32bit
arm64 - arm64bit

1. "make target/sonic-broadcom.raw" will create the compressed dd'able image.
2. This will also update the grub config files (device/dell/*/nos_to_sonic_grub.cfg) with the image versions.
