Hi,

The patch set of adding Firmware Update partition has been updated according to the published Firmware Update API spec(https://developer.arm.com/documentation/ihi0093/0000/). May I ask for your review on that again?

Hi,

Add some technical details.

The newly added Firmware Update service provides the functionality of updating firmware images. It provides a standard interface for updating firmware and it is designed as platform/bootloader independent. The nonsecure application can call this service to achieve the firmware update by integrating TF-M with, for example, OTA library in the nonsecure side.

The implementation provides a shim layer between the bootloader and the firmware update partition. Other bootloaders besides MCUboot should be easily ported with this partition.

Any comment is very welcomed!
