Ah sorry I missed that part of the email. I have no idea about this 
patch and what it attempts to do. I have not seen any posts or 
discussion about it and same goes for the SOURCES/4.11 directory.

IMO we should not have a SOURCES/4.11 directory until 4.11 is released 
so I think it should be emptied. When 4.11 is released this directory 
should contain all the approved source and to be approved there needs to 
be real test results from RTEMS where possible. Just building the tools 
and RTEMS is not sufficient. We have not reached a point where every 
architecture or BSP can be tested however we have made real progress and 
so as I said where possible we should run the tests and get the results. 
RTEMS should also make available the ability for users to run the tests 
and compare the results. Users being able to validate the tools they 
have against the expected results is very important.

The 4.11 tools are currently a mix of 4.8.3 and 4.9.1 with some upstream 
patches and newlib-26-Jul-2014 [1]. The gcc-4.9.1 release is being used 
for some targets that do not build or are not supported on 4.8.3, eg 
NIOS2. The recent newlib is required to get the RTEMS head to build.

Back to the point on rtems-tools being the master. It is as well as 
references to suitable web sites that host and provide support for the 
upstream project. For example the NIOS2 patch being used by the RSB is 
http://patchwork.ozlabs.org/patch/364504/. The RSB references this patch 
directly 
http://git.rtems.org/rtems-source-builder/tree/rtems/config/4.11/rtems-nios2.bset#n19.

The RTEMS project defines the tool set at the source level for a release 
and anyone can take that and package it anyway they like where ever they 
like. The RSB is just one possible way. Anyone packaging the tools can 
vary them anyway they like and so users need to decide on using those 
tools based on there merits.
