RE: [ECOS] Possible typo inhal/arm/arm9/var/current/include/hal_cache.h

OK, I'll have a look at that.  So far I have avoided running any of the
kernel tests because I have been focusing very intently on getting RedBoot
up and running, and have ignored anything not directly related to RedBoot.
Thus, I will feel comfortable saying at the end of the week that "I have
ported RedBoot to the OMAP", but there is still somme work to be done to
claim that I have ported eCos to the OMAP (most noticably, I have not done
any work at all with interrupts, consequently, I have not done any work at
all with the real time clock, consequently, I have not tried running any of
the "kernel specific" tests).

Anyway, I'll look at it.  Perhaps it will run fine even if I don't have
interrupts and the real time clock enabled.  Thanks.
