Subject: mpc85xx: allow mapping of cpu1 spin-table page
X-Git-Tag: v23.05.3~166
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=6261ae12e1161ebefa94f61a1c96f9febd7ed985;p=openwrt%2Fopenwrt.git

mpc85xx: allow mapping of cpu1 spin-table page

The no-map property was incorrectly added, which kept the system-memory
available on the WS-AP3825 limited to 190MB. We are allowed to map the
page containing the CPU1 spin-table, we are just not allowed to write to
it.

Fixes: 57d7382cb159 ("mpc85xx: increase available RAM on Extreme Networks WS-AP3825i")
