Hi Utkarsh, Please also fix some whitespace problems .git/rebase-apply/patch:23: trailing whitespace. ``Correct configuration of Newlib -`` .git/rebase-apply/patch:28: trailing whitespace. ``Threading in GCC support libraries -`` .git/rebase-apply/patch:31: trailing whitespace. done by the RTEMS specific cross-compiler. .git/rebase-apply/patch:32: trailing whitespace. .git/rebase-apply/patch:33: trailing whitespace. ``Provide preprocessor define __rtems__ -`` warning: squelched 1 whitespace error
And only use one blank line before the new section.
