This looks ok, along with the copyright clean-up. In the future please separate non-functional (style, copyright, etc) changes from functional patches to simplify review/approval/revision process. One question I do have from this: the minimum APPROX size is 180 (+CPU_PER_CPU_CONTROL_SIZE + CPU_INT

grub2 on old Linux Distributions (at least CentOS 7)

Hi Looking over the build sweep failures, I spotted this one (https://lists.rtems.org/pipermail/build/2021-November/030118.html) which would lean to their being a floor on older distributions. There is a software collection for a gcc8 for CentOS 7 but do we want to require it? This is for x86_64 t

Hi Looking in https://lists.rtems.org/pipermail/build/2021-November/030083.html, I'm not sure what explains this error: CC libfdt/fdt.o libfdt/fdt.c: In function 'fdt_ro_probe_': libfdt/fdt.c:27:11: error: 'FDT_ERR_ALIGNMENT' undeclared (first use in this function) return -FDT_ERR_ALIGNMENT;

Hi This looks like we need to bump the hash, submit a patch, or change to building with -Wno-error (https://lists.rtems.org/pipermail/build/2021-November/030047.html). Any ideas? FYI Chris.. this one may be on you to see if a hash bump fixes it. /usr/bin/cc -O2 -pipe -fbracket-depth=1024 -I/opt/

Re: grub2 on old Linux Distributions (at least CentOS 7)

Hi, indeed, centos 7 is bundled with gcc 4.8.5. Now, the question is, is centos 7 still supported by RTEMS? If so, then we will need to invent some machinery to check not only for commands but also for versions in cfg files? Also if we're doing this we need to check firmly we're really on old ce
