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.

  To: edk2-devel; +Cc: Ard Biesheuvel

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.

Please remove the sections about which toolchain to use and how to
build the package. edk2-build.sh is a Linaro invention that does not
exist upstream, and building platforms should be the same for all
platforms in edk2-platforms.

If your platform relies on SECURE_BOOT_ENABLE and/or HTTP_BOOT_ENABLE,
you can just change the default value to TRUE

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

So the line above becomes
