e482b3bee6 mx25: fix clock's calculation
* 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.

6136a6ddc9 ARM: imx: add lost 3rd imx-i2c device for mx35
During the reorganisation of the imx-i2c devices
(in 64de5ec168) the 3rd imx-i2c device
for the mx35 got lost. This patch adds the missing device.

68a2f7301a ARM: imx: Add iram allocator functions
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

9524705c86 MX35: Fix bogus L2 cache settings
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

35bab0589b ARM: imx: change the way spi-imx devices are registered
Group soc specific data in a global struct instead of repeating it for
each call to imxXX_add_spi_imxX.  The structs holding the actual data
are placed in .init.constdata and so don't do much harm.  Compared to
the previous approach this reduces code size to call imx_add_spi_imx.
