d5d7606c0c Use the TSLOG framework to record entry/exit timestamps for DELAY and 
_vprintf; these functions are called in many places and can contribute
meaningfully to the total time spent booting.

55dae242e6 Add and use a MMC_DECLARE_BRIDGE macro for declaring mmc(4) bridges 
as kernel drivers and their dependency onto mmc(4); this allows for
incrementing the mmc(4) module version but also for entire omission
of these bridge declarations for mmccam(4) in a single place, i. e.
in dev/mmc/bridge.h.

b440e965da o Another round fixes for mmc(4), mmcsd(4) and sdhci(4) regarding 
comments, marking unused parameters as such, style(9), whitespace,
  etc.
o In the mmc(4) bridges and sdhci(4) (bus) front-ends:
  - Remove redundant assignments of the default bus_generic_print_child
    device method (I've whipped these out of the tree as part of r227843
    once, but they keep coming back ...),
  - use DEVMETHOD_END,
  - use NULL instead of 0 for pointers.
o Trim/adjust includes.

c214a270f5 Allow setting access-width for UART registers. 
This is required for FDT's standard "reg-io-width" property
(similar to "reg-shift" property) found in many DTS files.

This fixes operation on Altera Arria 10 SOC Development Kit,
where standard ns8250 uart allows 4-byte access only.

631f432b0d Remove redundant cache initialization in JZ4780 SMP startup code 
This was done out of pure paranoia when hunting for bugs in cache
and is not really required.

7fd348080f The JZ4780 I2S can feed either the internal audio codec or the HDMI 
transmitter, but not both at the same time. This patch:

 - Adds a dev.pcm.0.internal_codec sysctl node for selecting between
   internal and external codec
 - Changes playback sample rate from 96 kHz to 48 kHz for HDMI compatibility
 - Enables i2s clock on codec access

47abdb10a0 Do not use read-modify-write on MSC control register. 
The register is write-only, so just write only bits we want.
