1161298251 Create a common set_stackptrs in sys/arm/machdep.c.
On single core devices set_stackptrs is only ever called with cpu = 0 in
initarm and will be identical to the existing function. On SMP this needs
to be implemented for sys/arm/mp_machdep.c, but the implementations are
identical for each SoC.

64dc1cf395 Implement MSI support.
MSI are implemented via Inbound Shared Doorbell 1 interrupts. Interrupts
are triggered by writing to Software Triggered Interrupt registeri (PCIe
card using physical address of this register in BAR0 space). There are 32
interrupts available. It can be increased by using Doorbell 2 and
Doorbell 3 registers to 96 interrupts.

  address to iicbus.

0bb13a26f0 Create default_parse_boot_param which, if FreeBSD /boot/loader support
is enabled, sets values based on the metadata passed in.  Otherwise
fake_preload_metadata is called.  Change the default parse_boot_param
to default_parse_boot_param.  Enable this functionality only on the mv
platform, which is where most of the code is from.

d39655d7a4 Modify all the arm platform files to call parse_boot_param passing in
the boot parameters from initarm first thing.  parse_boot_param parses
the boot arguments and converts them to the /boot/loader metadata the
rest of the kernel uses.  parse_boot_param is a weak alias to
fake_preload_metadata, which all the platforms use now, but may become
more extensive in the future.

Since it is a weak symbol, specific boards may define their own
parse_boot_param to interface to custom boot loaders.

07042bef45 Fix OF_finddevice error return value in case of FDT.
According to the open firmware standard, finddevice call has to return
a phandle with value of -1 in case of error.

This commit is to:
- Fix the FDT implementation of this interface (ofw_fdt_finddevice) to
  return (phandle_t)-1 in case of error, instead of 0 as it does now.
- Fix up the callers of OF_finddevice() to compare the return value with
  -1 instead of 0 to check for errors.
- Since phandle_t is unsigned, the return value of OF_finddevice should
  be checked with '== -1' rather than '<= 0' or '> 0', fix up these cases
  as well.

  (bus_generic_driver_added(9) since r52045 and bus_generic_print_child(9)

e4623c22fe Fix mv_gpio_in() for pin numbers that occupy bits 8-31 in GPIO registers.
The compiler will truncate the 32-bit return value of mv_gpio_value_get()
to match the 8-bit return value of mv_gpio_in(). A conditional expression
is used to have mv_gpio_in() always return 0 or 1 instead.

078b894c69 In arm_get_next_irq(), use the last IRQ argument in order to prevent
a hard hang due to an interrupt storm or stuck interrupt pin. We
return the next IRQ that is larger than the last one returned and
in doing so give all interrupts a fair chance of being handled.
Consequently, we're able to break into the kernel debugger in such
an event.

bda55b6adb Set of legacy mode SATA enchancements:
- Implement proper combined mode decoding for Intel controllers to properly
identify SATA and PATA channels and associate ATA channels with SATA ports.
This fixes wrong reporting and in some cases hard resets to wrong SATA ports.
- Improve SATA registers support to handle hot-plug events and potentially
interface errors. For ICH5/6300ESB chipsets these registers accessible via
PCI config space. For later ones they may be accessible via PCI BAR(5).
- For controllers not generating interrupts on hot-plug events, implement
periodic status polling. Use it to detect hot-plug on Intel and VIA
controllers. Same probably could also be used for Serverworks and SIS.
