Fwd: [PATCH] libgloss support for nios2 QEMU

[Joel Sherrill]

This looks like a solution for having a way to test the Nios II.

Sandra also mentioned a semi-hosted m68k so I wonder if that
is also an option.

If the BSP is no interrupts, console only like most of the gdb
based one, the BSP is easy and we get a way to test more.

This patch adds semihosting support for Nios II plus startup code and a
linker script for bare-board emulation with QEMU.  The QEMU side of things
requires this patch set

The semihosting code is pretty much a direct copy of the m68k
implementation, which was contributed by CodeSourcery years ago.  We've
been using this protocol in our toolchain distributions for Nios II for
some years now (plus other targets we've been asked to produce toolchains
for that don't already have some other semihosting protocol supported by
other tools).
