The mxc_init_l2x0() should really be an imx31/35 specific call.
The patch removes early_initcall from mxc_init_l2x0() and get imx31
and imx35 soc specific function calls mxc_init_l2x0(), so that it's
not necessarily to be called for all imx socs when we build single
image for multiple imx socs.
Thus the function can be renamed to imx3_init_l2x0() and put into
mm-imx3.c. It also changes the return type from integer to void.
From what I see, the integer was picked just to satisfy early_initcall
prototype.
With the patch 'ARM: l2x0: add empty l2x0_of_init' applied, the code
compiles even without CONFIG_CACHE_L2X0 enabled.

Subject: [PATCH] i.MX25 GPT clock fix: ensure correct the clock source
This patch ensures, that Linux will take the correct clock source (AHB_DIV)
for gpt in the ARM i.MX25 implementation. The currect code depends on the reset
defaults of the CCM_MCR register. So on some boards it could happen that the
UPLL is used for clock source, which results in faulty time behavior in Linux.
In this case all delays or sleeps will will be faktor 1.8 too long.

It might be not good to use software defined version to identify sdma

cases
* Remove the use of flag ESDHC_FLAG_GPIO_FOR_CD
* Adjust some machine codes to adopt the platform_data changes

On the recent i.mx (mx25/50/53), there is a gasket inside fec
controller which needs to be enabled no matter phy works in MII
or RMII mode.
The current code enables the gasket only when phy interface is RMII.
It's broken when the driver works with a MII phy. The patch uses
platform_device_id to distinguish the SoCs that have the gasket and
enables it on these SoCs for both MII and RMII mode.

The patch removes all the uses of cpu_is_mx1(). Instead, it uses
the .id_table of platform_driver to distinguish the uart device type,
IMX1_UART and IMX21_UART. The IMX21_UART type runs on all i.mx
except i.mx1.
A couple of !cpu_is_mx1 logic gets turned into is_imx21_uart,
as the codes wrapped there are really IMX21 type uart specific.
It also removes macro MX1_UCR3_REF25 and MX1_UCR3_REF30 which are
not used anywhere.

Software defined version number is not stable enough to be used
in device type naming scheme. The patch changes it to use implicit
soc name for spi device type definition. In this way, we can easily
align the naming scheme with device tree binding, which comes later.
It removes fifosize from spi_imx_data and adds devtype there, so that
fifosize can be set in an inline function according to devtype.
Also, cpu_is_mx can be replaced by inline functions checking devtype.

It is not good to have cpu_name and to_version encoded into sdma
firmware name as variables. For example, there are three TOs of
imx51 soc, the sdma script never changes since TO1, which means
all three TOs of imx51 uses TO1 version of sdma script. But we
have to prepare three identical firmwares, sdma-imx51-to1.bin
sdma-imx51-to2.bin and sdma-imx51-to3.bin, to have the kernel
capable of running on all three TOs.
The patch removes cpu_name and to_version from sdma platform data,
and instead uses fw_name to pass the firmware name, so that we can
pass the TO version where it's relevant and skip it where only one
firmware exists.
