Hi all,
I have playing around with a Malta board which has a MIPS32 24KEc core
(PR.ID = 2.0.1).
I was testing the CACHE instruction and I observed the following
*weird* behavior:
I try to lock a given range of addresses within the cache. I tried to
do so with both operations (i.e. Index store tag and Fetch&Lock). What
I observe is that the Fetch&Lock is locking much *less* lines than
what the index store tag does. Is there anyone who is aware of any
constrains/errata regarding this issue?

Best regards,
