The HDMI driver will attach a framebuffer device when a display is
connected. If the EDID can be read and contains a preferred mode, it
will be used. Otherwise the framebuffer will default to 800x600.
In addition, if the EDID contains a CEA-861 extension block and the
"basic audio" flag is set, audio playback at 48kHz 16-bit stereo is
enabled on the controller.

This is a stub for PMSU driver. Note that it cannot be used to set the
secondary core boot address during attach because drivers are attached
later than SI_SUB_CPU sysinit where cores are started.
Setting the boot address should be done manually in platform_mp_start_ap().

Current functionality is somewhat limited: driver assumes that there
is only one active IPU unit (IPU1) and that video output is DI0 and
video mode is 1024x768. For more advanced functionality driver requires
proper clock management which is work in progress. At the moment driver
assumes that pixel clock is configured by u-boot for 1026x768 mode.

though free + inactive only goes from ~35MB to ~42MB. We can
also boot a nanobsd image mostly (I had to hand tweak what was

Move the FDT stuff to the top. We're almost ready to pull the trigger
to moving over to FDT, but something in the MCI driver is freaking out

This commit introduces support for etherswitch devices that utilize SMI as
a way of accessing its registers. SMI register is located in address space
of mge -- access to it was exported through MDIO interface.
Attachment functions were enhanced so as to ensure proper initialisation
in both cases: 1) PHYs attached directly to mge, 2) PHYs attached to
switch device and switch attached to mge. Attachment of etherswitch device
depends on dts entry with compatible="mrvl,sw" property. If none is found,
typical PHY attachment procedure follows.
In case of switch attached, PHYs' status and configuration is accessible
via etherswitchcfg, and ifconfig shows always-up, non-configurable mge
interfaces.
Due to the fact that there may be simultaneous accessess to SMI
registers (e.g. from PHY attached to one of mge instances and switch
to the other), SMI access interlock was added. It is SX lock,
because sleep ability is necessary -- busy-waiting would result
in poor performance due to long delays required by hardware.
Underlying switch driver is obliged to use sleepable locks as well.

The latter is required for INTRNG, because of the hardware erratum
workaround installed by the linux folks into the imx6 FDT data, which remaps
an ethernet interrupt to the gpio device. In the non-INTRNG world we
intercept the call to map the interrupt and map it back to the ethernet
hardware (because we don't need linux's workaround), but in the INTRNG world
we lose the hookpoint where that remapping was happening, but we gain the
ability to work the way linux does by having the gpio driver dispatch the
interrupt.

There are other boards (namely the banana pi) that use exactly the same

Additionally, we are moving from static FDT support (DTB compiled
in-kernel) to DTB passed to kernel by the boot loader (ubldr). The u-boot
for these boards are already available on ports and as the crochet support
for these boards isn't committed yet, this should not bring any issues.
