b96008e410 In pmap_mapdev we correctly round the address off to the nearest page 
boundary, but we must also add the offset back on to the va we return.

6449092f51 Uncomment the call to cpu_idcache_wbinv_all() after the MMU has been 
enabled. It has been commented out for a reason I forgot but I suspect
does not apply anymore.
Technically speaking it's not required to do it, has the data and the
instruction cache have been disabled in _start(). However, it may change
in the future, so I don't want to rely on this behavior.

2e58b61962 Resurrect Skyeye support : 
Add a new option, SKYEYE_WORKAROUNDS, which as the name suggests adds
workarounds for things skyeye doesn't simulate. Specifically :
- Use USART0 instead of DBGU as the console, make it not use DMA, and           manually provoke an interrupt when we're done in the transmit function.
- Skyeye maintains an internal counter for clock, but apparently there's
no way to access it, so hack the timecounter code to return a value which
is increased at every clock interrupts. This is gross, but I didn't find a
better way to implement timecounters without hacking Skyeye to get the
counter value.
- Force the write-back of PTEs once we're done writing them, even if they
are supposed to be write-through. I don't know why I have to do that.

627a93886f Move the call to cpu_setup() before the call to vm_ksubmap_init(). 
vm_ksubmap_init() calls pmap_copy_page(), which uses the mini data cache
to do the copy, but we're running uncaching before cpu_setup().
For some reason it hasn't been a problem so far, but it is for the
PXA255.

58dbe8e93e Setting the rid of the resource is a good idea, but we still need to return

Retire pmap_track_modified().  We no longer need it because we do not
create managed mappings within the clean submap.  To prevent regressions,
add assertions blocking the creation of managed mappings within the clean
submap.
