The SH7750 is indeed an SH4, and yes, there is a HAL for that variant,
but it's presently unsupported by Red Hat (i.e., if it breaks you get
to keep both halves).
I know that there are some issues with caching in that HAL, but
otherwise it passes all our tests. Patches to rectify the caching
issues will obviously be accepted gladly :)
