Outdated information in Readme

[maxking]

Customization section of the readme.txt mentions about the build script at pre_os/build_xmon_pkg_linux.sh which can be used to change the memory size of the xmon but I couldn't find any such scripts in the ikgt-loader repo (which I think is inside xmon/loader). Also, since the repo has basically no history, I am not exactly sure if the information is incorrect or outdated.

Yes, good catch. That's probably an outdated information that was in 1.0 release and didn't get removed when 1.1 was released.

The new location for that is probably in pre_os/starter/xmon_desc.h (see STARTER_DEFAULT_LOAD_ADDR) though I have not tried that.
