Subject: arm: fix bare-metal memory setup.
X-Git-Tag: stable_2015_04_15~160
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=3a5c975fd7a0e6c8f25067c1794581056c01c22c;p=gem5.git

arm: fix bare-metal memory setup.

The bare-metal configuration option still configured memory with the old scheme
that no-longer works. This change unifies the code so there aren't any differences.
