Upgrading Packages

[Vikram Chundawat]

Hello, I have upgraded some packages and they seem work fine without
any issues. I have upgraded GCC,GDB,Make,GMP to
GCC-9.2.0,GDB-9.1,Make-4.3,GMP-6.2.0.

Project compiled successfully with errors.

I want to submit my modifications for review but the guide at
https://review.coreboot.org/Documentation/user-upload.html#_git_push seems
a bit confusing.

Can anyone help me?
Thank you
