Warner Losh 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).

Warner Losh f535f4234a Minor style(9) nit. 2012-08-27 04:08:43 +00:00
Warner Losh 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.

Oleksandr Tymoshenko 86bce74937 Move unmask IRQ function call up to nexus device level. 
FDT-enabled targets were broken after r238043 that relies

nexus device for ARM platforms did job only partially:
setting handler but not unmasking interrupt. Unmasking
was performed by platform code.

Warner Losh a68d1f48b9 Complete the transition away from newbus to populate the children to 
the linker set of CPU modules.  The newbus method, although clever,
had many flaws: it didn't really support multiple SoC, many of the
comments about order were just wrong, and it did a few things far too
late to be useful.  delay and cpu_reset now work much earlier in the
boot process.
