Implemented features related to secure boot and DRI (downloading the image and storing on flash),
library has utility of file read and write operations for fat and raw flash partition, it reads file path
and load the file content using configuration file.

I will mention it once here but it applies to all patches:
please don't put spaces after ( or before )
please do put spaces before (
please don't use 'backward' (yoda style) comparisons
