[v2] Nios II generic board config and semihosting support

[Qemu-devel] [PATCH v2 0/2] Nios II generic board config and semihosting support

Posted by Julian Brown 7 years, 5 months ago

This is a second attempt at sending this patch series:

http://lists.gnu.org/archive/html/qemu-devel/2018-05/msg04259.html

with some git format-patch/send-email hiccups ironed out
(hopefully). The patch contents are unchanged.

OK, or any comments?

Thanks,

Julian

[Qemu-devel] [PATCH v2 1/2] Add generic Nios II board.

Posted by Julian Brown 7 years, 5 months ago

This patch adds support for a generic MMU-less Nios II board that can
be used e.g. for bare-metal compiler testing.  Nios II booting is also
tweaked so that bare-metal binaries start executing in RAM starting at
0x00000000, rather than an alias at 0xc0000000, which allows features
such as unwinding to work when binaries are linked to start at the
beginning of the address space.

The generic_nommu.c parts are by Andrew Jenner, based on code by Marek
Vasut.

Originally by Marek Vasut and Andrew Jenner.
