There are an increasing number of ARM Cortex-M based boards around, and I'd like to get a cross-compilation toolchain for them into the Fedora repositories.
I hope you're more successful with that than I was. I found a resounding lack of interest when I put an arm-none-eabi binutils up for review some time back, in preparation for corresponding gcc and gdb packages.
I agree with Ralf that this is a different target than arm-gp2x-linux, and should be totally independent of it. However, there might be overlap with the cross-gcc package, which builds a gcc-arm-linux-gnu package. That triple sounds like it is for cross compiling to a Linux ARM platform, but note that some of the other triples that they build, e.g., c6x-linux-gnu arm-h8300-linux-gnu, are actually for non-Linux target platforms, so possibly the gcc-arm-linux-gnu package might be suitable for non-Linux ARM Cortex-M3 development.
I've personally had much better luck with the Mentor Sourcery (formerly CodeSourcery) distribution of the GNU tools for targeting ARM than with the official FSF distribution. The Mentor Sourcery team seems to be one of the largest contributors to maintaining the GCC ARM target, and their distribution has bug fixes and such *much* earlier than the official FSF distribution. It was my intent to package the Sourcery toolchain, but I didn't push it any further when there was no interest in the binutils.
I'm doing cross-development for a custom board with an Energy Micro EFM32GG380F1024, which is a "Giant Gecko" part containing a Cortex-M3 core, 1MB flash, 128KB RAM, full-speed USB, and a bunch of other peripherals. I started with the original Gecko part because it was the only ultra-low-power ARM chip with a decent amount of RAM back in 2010, but there may be a few others getting close to it now.
