EFI firmware determines where to load the GRUB EFI at runtime, and so the addresses of debug symbols are not known ahead of time. There is a command defined in the gdb_grub script which will load the debug symbols at the appropriate addresses, if given the application load address for GRUB. So add a command named "gdbinfo" to allow the user to print this GDB command string with the application load address on-demand. For the outputted GDB command to have any effect when entered into a GDB session, GDB should have been started with the script as an argument to the -x option or sourced into an active GDB session before running the outputted command. Documentation for the gdbinfo command is also added.

See the file NEWS for a description of recent changes to GRUB 2. See the file INSTALL for instructions on how to build and install the GRUB 2 data and program files. See the file MAINTAINERS for information about the GRUB maintainers, etc. If you found a security vulnerability in the GRUB please check the SECURITY file to get more information how to properly report this kind of bugs to the maintainers. Please visit the official web page of GRUB 2, for more information. The URL is <http://www.gnu.org/software/grub/grub.html>. More extensive documentation is available in the Info manual, accessible using 'info grub' after building and installing GRUB 2. There are a number of important user-visible differences from the first version of GRUB, now known as GRUB Legacy. For a summary, please see: info grub Introduction 'Changes from GRUB Legacy'
