arm-elf vs arm-linux

[Valentin Longchamp <valentin dot longchamp at epfl dot ch>]

Hello,

I'm working on a project where we are designing our open-hardware
embedded board for robotics. It's for future academic projects, so we
would like that every student and anyone can use the tools, that's why
we make open-hardware and we want to use the GNU toolchain.

Our target processor is going to be an ARM1136, so armv6. My question is
about the two main target toolchains I could build : what is the
difference between arm-elf and arm-linux.

Since we want to use RedBoot bootloader (and maybe want to use eCos as
well), I know that they tell to use the arm-elf toolchain.
But we also want to use linux (we have some kernel patches for our
processor and its dev board), they tell to use arm-linux.

What's the real difference between those two targets ? I know that of
course arm-elf won't give support for glibc of course ! Because if they
don't differ that much, it would be great not to have to build and use
two different toolchains for when I want to build my bootloader or when
I want to build my linux kernel or the application I would run on it !

Anyone has a clue ?

Regards,

Valentin Longchamp
