not have enough information to reliably setup GPIO pins. Do it when

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.

Convert Marvell ARM platforms to FDT convention.

Convert Marvell ARM platforms to FDT convention.

The following systems are involved:

- DB-88F5182
- DB-88F5281
- DB-88F6281
- DB-78100
- SheevaPlug

This overhaul covers the following major changes:

- All integrated peripherals drivers for Marvell ARM SoC, which are
currently in the FreeBSD source tree are reworked and adjusted so they
derive config data out of the device tree blob (instead of hard coded /
tabelarized values).

- Since the common FDT infrastrucutre (fdtbus, simplebus) is used we say
good by to obio / mbus drivers and numerous hard-coded config data.

Note that world needs to be built WITH_FDT for the affected platforms.

Adjust Marvell Discovery (MV78xxx) support to recognize newest chip revisions,
handle Z0 revision (early silicon) explicitly due to its quirks.

Obtained from: Marvell, Semihalf

Improve and extend Marvell SOCs platform code.

- Allow for setting per platform MPP/GPIO configuration in the kernel, so
that we can override all settings firmware might set.

- Set decode windows

- Allow for setting per platform MPP/GPIO configuration in the kernel, so
that we can override all settings firmware might set.

- Set decode windows for the remaining on-chip peripherals: CESA, SATA and XOR.

- Improve handling of USB controllers so that all port are available on the
given SOC/platform (e.g. up to three on DB-78xxx), this includes rework of
USB decode windows set-up.

- Other minor fixes and cosmetics.

Minor style(9) corrections.

Introduce basic support for Marvell families of system-on-chip ARM devices:

* Orion

* Orion
- 88F5181
- 88F5182
- 88F5281

* Kirkwood
- 88F6281

* Discovery
- MV78100

The above families of SOCs are built around CPU cores compliant with ARMv5TE
instruction set architecture definition. They share a number of integrated
peripherals. This commit brings support for the following basic elements:

* GPIO
* Interrupt controller
* L1, L2 cache
* Timers, watchdog, RTC
* TWSI (I2C)
* UART

Other peripherals drivers will be introduced separately.
