Subject: [U-Boot-Users] do_bootm() and flush_cache()
Date: Tue, 22 Mar 2005 20:40:38 -0500 [thread overview]
Message-ID: <4240C916.30901@psyent.com> (raw)
I'm looking for some guidance:
On some processors (e.g. Nios-II), the instruction and
data caches can't be disabled. The code for loadb, loads,
etc. call flush_cache() ... so life is good.
But after reviewing do_bootm(), I don't see where the
caches are flushed. A call to flush_cache() after
moving/decompressing the image seems appropriate, but
I'm not sure if this would break other architectures ...
... do I need to wrap an ifdef around a call to
flush_cache() ?
Regards,
--Scott
