Add the imx sdhci controller.

Move Open Firmware device root on PowerPC, ARM, and MIPS systems to
a sub-node of nexus (ofwbus) rather than direct attach under nexus. This
fixes FDT on x86 and will make coexistence with ACPI on ARM systems easier.
SPARC is unchanged.

Add the missing ')' at end of sentence. Reword it to use a more common idiom.

Pass the kernel physical address to initarm through the boot param struct.

Make functions only used in vfp.c static, and remove vfp_enable.

Fix __syscall on armeb EABI. As it returns a 64-bit value it needs to
place 32-bit data in r1, not r0. 64-bit data is already packed correctly.

Use abp_physaddr for the physical address over KERNPHYSADDR. This helps us
remove the need to load the kernel at a fixed address.

Remove references to PHYSADDR where it's used only in debugging output.

Dynamically generate the page table. This will allow us to detect the
physical address we are loaded at to change the mapping.

Add common bus_space tag definition shared for most supported ARMv6/v7 SoCs.
Correct license statements to reflect the fact that these files were all
derived from sys/arm/mv/bus_space.c.

In pmap_unmapdev(), remember the size, and use that as an argument to
kva_free(), or we'd end up always passing it a size of 0

In pmap_mapdev(), first check whether a static mapping exists,

Convert TI static device mapping to use the new arm_devmap_add_entry(),

Use the common armv6 fdt_bus_tag defintion for tegra instead of a local copy.

Eliminate use of fdt_immr_addr(), it's not needed for tegra

Convert lpc from using fdt_immr style to arm_devmap_add_entry() to make
static device mappings.

Retire machine/fdt.h as a header used by MI code, as its function is now
obsolete. This involves the following pieces:
- Remove it entirely on PowerPC, where it is not used by MD code either
- Remove all references to machine/fdt.h in non-architecture-specific code
(aside from uart_cpu_fdt.c, shared by ARM and MIPS, and so is somewhat
non-arch-specific).
- Fix code relying on header pollution from machine/fdt.h includes
- Legacy fdtbus.c (still used on x86 FDT systems) now passes resource
requests to its parent (nexus). This allows x86 FDT devices to allocate
both memory and IO requests and removes the last notionally MI use of
fdtbus_bs_tag.
- On those architectures that retain a machine/fdt.h, unused bits like
FDT_MAP_IRQ and FDT_INTR_MAX have been removed.

Add #include <machine/fdt.h> to a few files that used to get it via pollution

Enable the mv cesa security/crypto device by providing the required property
in the dts source, and adding the right devices to the kernel config.

Remove dev/fdt/fdt_pci.c, which was code specific to Marvell ARM SoCs,
related to setting up static device mappings. Since it was only used by
arm/mv/mv_pci.c, it's now just static functions within that file, plus
one public function that gets called only from arm/mv/mv_machdep.c.

Switch RPi to using arm_devmap_add_entry() to set up static device mapping.

Allow 'no static device mappings' to potentially work.

Don't try to find a static mapping before calling pmap_mapdev(), that logic
is now part of pmap_mapdev() and doesn't need to be duplicated here.

Switch a10 to using arm_devmap_add_entry() to set up static device mapping.

Add vt support for RPi. (No early stage yet.)

Add vt support for RPi. (No early stage yet.)

Teach nexus(4) about Open Firmware (e.g. FDT) on ARM and MIPS, retiring
fdtbus in most cases. This brings ARM and MIPS more in line with existing
Open Firmware platforms like sparc64 and powerpc, as well as preventing
double-enumeration of the OF tree on embedded PowerPC (first through nexus,
then through fdtbus).

This change is also designed to simplify resource management on FDT platforms
by letting there exist a platform-defined root bus resource_activate() call
instead of replying on fdtbus to do the right thing through fdt_bs_tag.
The OFW_BUS_MAP_INTR() and OFW_BUS_CONFIG_INTR() kobj methods are also
available to implement for similar purposes.

MFC after: 6 weeks

Remove #include <machine/frame.h> from all the arm code that doesn't
really need it. That would be almost everywhere it was included. Add
it in a couple files that really do need it and were previously getting
it by accident via another header.

Convert bcm2835_mbox to the new mbox interface.

Enable syscons framebuffer support for bcm2835. It makes possible to run Xorg
on Raspberry Pi.
o convert mmap address to physical.
o add FBIOGTYPE ioctl handler - allow to get screen resolution by new
xf86-video-scfb driver.

Fix background color calculation

Add makeshift implementation for framebuffer console's cursor

Basically it's replica of VersatilePB code which is replica of XBox FB
code. All of them are linear framebuffers and should have common bits
moved to reusable framework.

- Add colors support for text console

Add barebone Raspberry Pi port. Supported parts:
- Interrupts controller
- Watchdog
- System timer
