Dear Tom Rini,
Hey all,
In commit b8adb12 the cache flushing behavior was changed for the EHCI stack. This change showed a few different problems on TI platforms (where our cacheline size is 64 not 32).
Good thing, it made a bug surface ;-)
First, the dcache_off call that ehci-omap had been doing was now not happening soon enough to paper over the cache issues.
Hm, is the dcache_off() call implemented properly so nothing is lost when you shut off the cache btw?
As best I can tell, yes. It will do a dcache_flush_all() and then set the correct bits.
