- Improve random number generation during early Sonic initialization by providing SW updates to Linux entropy value.
- Improve handling of platform In-Band management port
This commit provides the following updates to the Nokia ixs7215 platform
1. The Marvell Armada-38x SOC requires SW assistance to improve the system
entropy value available early on in the Sonic boot sequence.
2. The Nokia ixs7215 platform does not have a dedicated Out-Of-Band (OOB) mgmt
port and thus requires additional logic to optionally support configuring
front panel port 48 as an In-Band mgmt port. This commit provides additional
logic to manage and maintain the operation of this In-Band mgmt port.
