8713fad4de Tune xDMA interface slightly:
o Move descriptors allocation to DMA engine driver
o Add generic xdma_request() routine
o Add less-generic scatter-gather application based on xdma interface

Typical operation flow in peripheral device driver is:

1. Get xDMA controller
sc->xdma_tx = xdma_ofw_get(sc->dev, "tx");

2. Allocate virtual channel
sc->xchan_tx = xdma_channel_alloc(sc->xdma_tx, caps);

3. Setup transfer status callback
xdma_setup_intr(sc->xchan_tx, my_tx_intr, sc, &sc->ih_tx);

4. Request a transfer(s)
ret = xdma_request(sc->xchan_tx, &req);

5. Free the channel
xdma_channel_free(sc->xdma_tx);

6. Free the controller
xdma_put(sc->xdma_tx);

3308d36a5e Align OF_getencprop_alloc API with OF_getencprop and OF_getprop_alloc
Change OF_getencprop_alloc semantics to be combination of malloc and
OF_getencprop and return size of the property, not number of elements
allocated.

For the use cases where number of elements is preferred introduce
OF_getencprop_alloc_multi helper function that copies semantics
of OF_getencprop_alloc prior to this change.

This is to make OF_getencprop_alloc and OF_getencprop_alloc_multi
function signatures consistent with OF_getencprop_alloc and
OF_getencprop_alloc_multi.

Functionality-wise this patch is mostly rename of OF_getencprop_alloc
to OF_getencprop_alloc_multi except two calls in ofw_bus_setup_iinfo
where 1 was used as a block size.

assym is only to be included by other .s files, and should never
actually be assembled by itself.

55fe5887ff 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.

b432c84c13 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.

804af8e481 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.

69f1ecb8f8 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.

1c2894456e 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.

9797927a90 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
