17659d7de9 Timer: Remove reset_timer_masked()
In some circumstances, reset_timer_masked() was called be timer_init() in
order to perform architecture specific timer initialisation. In such
cases, the required code in reset_timer_masked() has been moved into
timer_init()

aadcfc179a OMAP[34]: fix broken timer
As implemented now the timer used to implement __udelay counts
to 0xffffffff and then gets stuck there because the the programmed
reload value is 0xffffffff.  This value is not only wrong but
illegal according to the reference manual.

One can reproduce the bug by leaving a board at the u-boot prompt
for sometime then issuing a sleep command.  The sleep will hang
forever.

The timer is a count up timer that reloads as it rolls over
from 0xffffffff so the correct load value is 0.

Change TIMER_LOAD_VAL from 0xffffffff to 0 and introduce
a new constant called TIMER_OVERFLOW_VAL set to 0xffffffff.

b03c8403cd OMAP: Timer: Replace bss variable by gd
Reuse the gd->tbl value for timestamp and add gd->lastinc for lastinc bss
values in the OMAP timer driver.

The usage of bss values in drivers before initialisation of bss is forbidden.
In that special case some data in .rel.dyn gets corrupted.

674e0b217f ARMV7: Fix udelay for OMAP4
The OMAP4 x-load code sets gptimer1 clock source to 32Khz.  This isn't
acceptable for udelay.  This patch changes from gptimer1 to gptimer2,
which uses sys_clk at 38.4 Mhz.
