In [changeset:"bdcc81434353ee4f1d01aafe1a85627889fe53bc/rtems" bdcc814/rtems]:

sparc: Add workaround for GRLIB-TN-0011

Affected components are the GR712RC, UT699, UT699E, UT700, and
LEON3FT-RTAX. Strictly, the workaround is only necessary if the MMU is
enabled. Use FIX_LEON3FT_B2BST to enable the workaround. This is not
100% appropriate, but the best thing we can use to enable the
workaround.

Close #4551.
