* get_rate_arm : when 400MHz clock is selected (cctl & 1<<14),
ARM clock is 400MHz (MPLL * 3 / 4) and not 800MHz
* get_rate_per : peripherals's clock is derived from AHB and not
from IPG (ref manual : figure 5-1)
* can2_clk : use the correct ID
* without this patch, peripherals getting their clock from PER
clocks work fine because of the 2 errors which fix themselves
(ARM clock x 2 and per clock actually based on IPG which is AHB/2)
but flexcan can't work as it gets its clock from IPG and thus
calculates its bitrate using a reference value which is twice
what it really is.

Add IRAM(Internal RAM) allocation functions using GENERIC_ALLOCATOR.
The allocation size is 4KB multiples to guarantee alignment. The
idea for these functions is for i.MX platforms to use them
to dynamically allocate IRAM usage.
Applies on 2.6.36-rc7

Documentation/gpio.txt specifies that the value argument to
gpio_set_value() should be handled as a boolean (E.G. != 0 is high),
so use the same logic as in _set_direction().

i.MX35 CPUs marked with "MCIMX357CJQ5C M99V CTHA0943B" are coming with bogus
L2 cache settings. If these settings are kept unmodified prior enabling the L2
cache the CPU runs amok immediately when its enabled.
This fix should not hurt already working CPUs, as they are using the written
register value already.
Its currently unknown if its possible to detect the production lot from the
software to fix only affected CPUs.
While at it, make sure that mxc_init_l2x0 is only executed on i.MX31/35

The first argument to I2C_BOARD_INFO is used to assign .type, so it should
not be specified a second time.
