Subject: X86: Change how the default disk image gets set up.
X-Git-Tag: stable_2012_02_02~627
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=c4b81d311e824580666e1a620576a59528702b27;p=gem5.git

X86: Change how the default disk image gets set up.

The disk image to use was always being forced to a particular value. This
change changes what disk image is selected as the default based on the
architecture being built. In the future, a more sophisticated system might be
used that selected a path based on certain rules instead of relying on one off
file names.
