Hi Supreeth,

This patch can't be applied to the lasted code base SHA-1: 33022e.

Subject: [edk2] [edk2-test][PATCH v2] SctPkg/Tools: Fix incorrect line ending detection by GenBin tool

From: Lokesh B V <lokesh.bv@arm.com>

Some windows editors uses "\r\n" for line feed. While processing uefi sct testcase info file, the GenBin tool logic to skip line feed doesn't consider the presence of carraige return(\r) in line feed. So this results in incorrect format error.

Fixed this issue by changing logic of Trim and Getline functions used in GenBin source code.
