Earlier BeagleBoards were using pad AH8 muxed to GPIO29 for MMC write-protect.
However, this signal has been changed to pad AG9 in board revision C2.
Fix this by adding mux configuration for pad AG9, runtime check for board
revisions and set the gpio number and pad muxing accordingly.

The omap_device code provides a mapping of omap_hwmod structures into
the platform_device system, and includes some details on external
(board-level) integration. This allows drivers to enable, idle, and
shutdown on-chip device resources, including clocks, regulators, etc.
The resources enabled and idled are dependent on the device's maximum
wakeup latency constraint (if present).
At the moment, omap_device functions are intended to be called from
platform_data function pointers. Ideally in the future these
functions will be called from either subarchitecture-specific
platform_data activate, deactivate functions, or via an custom
bus/device type for OMAP.

OMAP SoCs can be considered a collection of hardware IP blocks
connected by various interconnects. The bus topology and device
integration data is somewhat more complex than platform_device can
encode. This patch creates code and structures to manage information
about OMAP on-chip devices ("hardware modules") and their integration
to the rest of the chip. Hardware module data is intended to be
generated dynamically from the TI hardware database for the OMAP4
chips and beyond, easing Linux support for new chip variants.
This code currently:
- resets and configures all hardware modules upon startup, reducing bootloader
dependencies;
- provides hooks for Linux driver model code to enable, idle, and shutdown
hardware modules (forthcoming patch);
- waits for hardware modules to leave idle once their clocks
are enabled and OCP_SYSCONFIG bits are set appropriately.
- provides a means to pass arbitrary IP block configuration data (e.g.,
FIFO size) to the device driver (via the dev_attr void pointer)
In the future this code is intended to:
- estimate interconnect bandwidth and latency characteristics to
ensure constraints are satisfied during DVFS
- provide *GRPSEL bit data to the powerdomain code
- handle pin/ball muxing for devices
- generate IO mapping information dynamically
- supply device firewall configuration data
- provide hardware module data to other on-chip coprocessor software
- allow the removal of the "disable unused clocks" code in the OMAP2/3
clock code
This patch represents a collaborative effort involving many people from TI,
Nokia, and the Linux-OMAP community.

Most board-*.c files read configuration data from the bootloader in
their .init_machine() function. This needs to happen earlier, at some
point before omap2_init_common_hw() is called. This is because a
future patch will use the bootloader serial console port information
to enable the UART clocks earlier, immediately after omap2_clk_init().
This is in turn necessary since otherwise clock tree usecounts on
clocks like dpll4_m2x2_ck will be bogus, which can cause the
currently-active console UART clock to be disabled during boot.

This patch provides the debugfs entries and a function which will be
called by the PM code to register the time spent per domain per
state. Also some new fields are added to the powerdomain struct to
keep the time information.
NOTE: As of v2.6.29, using getnstimeofday() after drivers are
suspended is no longer safe since the timekeeping subsystem is also
suspended as part of the suspend process. Instead use sched_clock()
which on OMAP returns the 32k SYNC timer in nanoseconds.
Also, do not print out status for meta powerdomains (dpll*)
