5c9f7b1a91 Initialize vm_max_kernel_address on non-FDT platforms. (This should have 
been included in r246926.)

The second parameter to pmap_bootstrap() is redundant.  Eliminate it.

6859e74003 Use the RTC unit to get the time. This works on all known AT91SAM9* 
processors, either on reboot or after power down with battery backup.
However, the AT91RM9200 RTC always resets on reboot making it just
about useless at the moment (if we support a low-power mode or an
extended sleep mode, it might become useful).

1161298251 Create a common set_stackptrs in sys/arm/machdep.c. 
On single core devices set_stackptrs is only ever called with cpu = 0 in
initarm and will be identical to the existing function. On SMP this needs
to be implemented for sys/arm/mp_machdep.c, but the implementations are
identical for each SoC.

f22f156e0b Make this work on the AT91SAM9G20: 
o Disable multi-block operations: they sometimes fail.
o Don't use the PROOF bits yet: they hang the system hard.
o Disable the the multi-block operations for !rm9200, but it
  still doesn't help.
o Fix writing < 12 bytes errata to actually work.
o Enable, for the moment, reporting extra bytes soaked up.

683bb97c9f When copying data, use memcpy instead of bcopy. It matches the

Also, set the need to use the workaround flag before we actually need
to use it, rather than after.

0f30f5d36b Bring in the multi-block patches for mci. These required extensive 
restructuring of the driver.  I've tried to preserve the other silicon
workarounds that we've added over the years, but haven't had a chance
to extensively test on other hardware.  On my AT91RM9200 with 30MHz/1
wire/64 block transfers, I've been able to go from ~.66MB/s to
2.25MB/s in the simple tests I performed, almost a 3.5x improvement.
This cuts the boot time almost in half when everything else goes
right (timed from rtc message to login: prompt).

b8e36ef7e0 Don't puprosely overclock the SD bus to 30MHz, make the user 
explicltly enable that.  The driver chose to use 60MHz / 2 (30MHz)
most of the time rather than 60MHz / 4 (15MHz) based on the Linux
driver of the time.  This pushes the spec a little in order to not
suffer the penalty of running at 15MHz.  However, when other bus
masters are active in the system, and the user tries 4-wire mode, the
internal bus arbitration would fail with data loss as a result.

86bce74937 Move unmask IRQ function call up to nexus device level. 
FDT-enabled targets were broken after r238043 that relies
on device up the hierarchy to properly setup interrupt.
nexus device for ARM platforms did job only partially:
setting handler but not unmasking interrupt. Unmasking
was performed by platform code.
