Subject: [PATCH] MIPS: BMIPS: Fix thinko to release slave TP from reset
|
|
|
|
Commit 4df715aa ["MIPS: BMIPS: support booting from physical CPU other
|
|
than 0"] introduced a thinko which will prevents slave CPUs from being
|
|
released from reset on systems where we boot from TP0. The problem is
|
|
that we are checking whether the slave CPU logical CPU map is 0, which
|
|
is never true for systems booting from TP0, so we do not release the
|
|
slave TP from reset and we are just stuck. Fix this by properly checking
|
|
that the CPU we intend to boot really is the physical slave CPU (logical
|
|
and physical value being 1).
