[Qemu-devel] [PATCH v5 0/4] Misc sam460ex improvements

[BALATON Zoltan <balaton@eik.bme.hu>]

These are the remaining patches for sam460ex needed to implement RTC
and get AmigaOS to boot. The sm501 patches are also needed but that's
now a separate series. I'd appreciate if this could be reviewed and
merged before the imminent 3.0 freeze.

I think only patch 1/4 (i2c rewrite) is a bit more complex but given
that originally it was only a stub and previous patches just hacked it
for u-boot IMO it does not worth trying to make incremental changes to
the previous nonsense behaviour instead of replacing it with a more
proper implementation which is what this patch does. Basically it
implements the 4 byte FIFO for mdata register and implements
interrupts the device should generate. Considering that this device is
only used on some not too well maintained boards it should be low risk
to make this change.

Patches 1-3 are for RTC emulation, patch 4 is new and is needed by
AmigaOS.
