When EEPROM is detected by board init code, read MAC out of EEPROM and
call the EMAC init routine passing the MAC address.  If EEPROM is not
found, then device code has a backup call to EMAC init.

Also, original i2c-emac code removed.

This patch adds an interface by which other kernel code can read/write
detected EEPROM.

The platform code registers a 'setup' callback with the
at24_platform_data.  When the at24 driver detects an EEPROM, it fills
out the read and write functions of at24_iface and calls the setup
callback.  The platform code can then use the read/write functions in
the at24_iface struct for reading and writing the EEPROM.

re-assert THRE correctly.

Recent changes to tighten the check for UARTs that don't correctly
re-assert THRE caused problems when such a UART was opened for the second
time - the bug could only successfully be detected at first initialization.
This patch stores the information about the bug in the bugs field of the
port structure when the port is first started up so subsequent opens can
check this bit even if the test for the bug fails.

This patch fixes the following annoying warning:

INFO: task twl4030 gpio:283 blocked for more than 120 seconds.
"echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message.
twl4030 gpio  D c027e9dc     0   283      2

 r5:00000000 r4:00000000

Which is printed every 120 seconds by the softlockup code (see
'check_hung_task()' function, introduced by on Jan 2008 by commit
82a1fcb9).

The reason is that the "twl4030 gpio" kthread is created but is not started
immediatelly. And in fact it may never start, because TWL3040 interrupts
may never happen and hence, the 'twl4030_gpio_unmask_irqchip()' function
is never run. This makes the softlockup detection code unhappy.

Fix this by running the "twl4030 gpio" kernel thread in at the end of the
'gpio_twl4030_init()' initialization function. Since the 'gpio_pending_unmask'
global variable is 0 at that time, the tread ('twl4030_gpio_unmask_thread()')
will effectively do nothing and go sleep. This makes the softlocup detection
code happy.

There is suspicion that the 32kHz input clock to the OMAP may be noisy
on BeagleBoards.  On OMAP2/3 GPTIMER1, this can cause the timer
counter register to warp to unknown values or miss interrupt
conditions.  So, use GPTIMER12 instead, which apparently has its own
secure 32kHz oscillator and will hopefully not be prone to the
suspected sys_32k glitches.

This is only a workaround.  If sys_32k is noisy, other system peripherals
may be affected.

This workaround is a collective product of several people, most notably

Add Kbuild code to allow the builder to select which GPTIMER block to use
for the Linux clockevents timer.  Practical choices at this point are
GPTIMER1 or GPTIMER12.  Both of these timers are in the WKUP powerdomain,
and so are unaffected by chip power management.  GPTIMER1 can use sys_clk
as a source, for applications where a high-resolution timer is more important
than power management.  GPTIMER12 has the special property that it has
the secure 32kHz oscillator as its source clock, which may be less prone
to glitches than the off-chip 32kHz oscillator.  But on HS devices, it may
not be available for Linux use.

At this point, it appears that most boards are fine with GPTIMER1, but
Beagle should use GPTIMER12.
