The core has a bit for swapping packet data endianism.
Reset default from Cadence is off. Xilinx however, that uses this core on the
Zynq SoCs, opted for on. Turn it off for all devices.

The macb/gem core is used by the Zynq SoC. In preparation of sharing
the macb driver between at91 and Zynq, rename the platform data to
'struct macb_platform_data', and move the definition to a common
location.

If a key is pressed but not released before booting and the key is
connected to an active low gpio it's not detected. This patch solves
that.

This allows us to better detect whether a clk is enabled or not.
- If we can ask a clk, ask it. If it's enabled, go on and ask parents
- If we can't ask it, but it can be enabled, depend on the enable_count.
if it's positive, go on and ask parents
- If we can't ask it and it cannot be enabled, assume it is enabled
and ask parents.
This makes the CLK_ALWAYS_ENABLED unnecessary, since the fixed clk now
always returns 1 in its is_enabled callback.

Some systems are runnignfrom a very limited SRAM, but have a huge
malloc space in SDRAM. The bss normally is in SRAM, so we should
avoid having big structures there. The gpio_desc table is 3072 bytes
big, so allocate it dynamically instead.

struct bus_type contains an embedded struct device_d which is quite
a big structure. Dynamically allocate this instead to save the space

This patch fix chipidea-imx usb initialization.
"imx_chipidea_port_init" was moved before PORTSC setup in the
commit "USB i.MX chipidea: implement post init support". This
change breaks usb function with ULPI. Patch moves port initialization
back after PORTSC setup, so it works again.

With 2k NAND flashes the data layout in memory is not what is
written on the flash device. This leads to the result that the
factory provided bad block markers are not recognized correctly.
To preserve the factory bad block information the i.MX NAND driver
will not scan for the bad blocks itself when there is no flash based
bbt available, because the mtd layer would do so based on wrong
information. Instead, a new command is introduced which allows to
manually create a flash bbt based on the correct information.
As this command is tightly coupled to mtd and the i.MX NAND driver
the command is placed under drivers/mtd/nand/ instead of commands/
where a command normally belongs to.

The information which kind of bbt (if any) is used is hidden somewhere
in the NAND layer. Expose it to a device parameter to make it detectable
and visible during runtime.
