[edk2] [PATCH v1 0/4] edk2-platforms:Comcast:Rdk Qemu platform for RDK UEFI applications
Posted by kalyan-nagabhirava, 1 week ago
Linaro and RDK are  working on standardizing the boot process for RDK  STB boxes using Uefi.
we implmented couple of RDK UEFI apllications(secure boot and DRI ) which are  tested on
RDK qemu platform.

[edk2] [PATCH v1 2/4] edk2-platforms:comcast: RDK boot manger Library implementation
Posted by kalyan-nagabhirava, 1 week ago
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.
