Some boards have board specific special clock setups. These are now
done in the SoC specific clock drivers.
It is assumed that most board specific clock setup is done based on
copy/paste from U-Boot. The generalized clock setup differs from
some boards:
- ioclk are adjusted to 480MHz
- ssp clocks are adjusted to 96MHz
- enet out clock is enabled
Some boards adjusted the ioclk to 320MHz and the ssp clock to 160MHz.

MXS needs some special MXS specific clock types:
- pll
- ref (fractional divider)
- busy divider (divider with additional busy bit to poll on a rate change)
- lcdif (Combined clock out of a fractional divider, a divider and a gate.

On MXS we need to poll the busy bit when changing a clock rate, but only
when the parent clocks are enabled. This exposes the already present
function clk_is_enabled which is suitable for this job.

Some tftp servers (for example netkit-tftp) do not pass the filesize.
Add a workaround for read_file which reads the file into a temporary
file which then is copied to a buffer.

The i.MX gpio driver doesn't have dependencies, so initialize
it in a core_initcall to have the gpio functions available earlier.
Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
This moves the CCM drivers to core_initcall since this has no dependencies.
This way we can be sure that the clock for the clocksource is available in
at postcore_initcall time.

The same value as used in Mainline and Freescale U-Boot. This might
increase the stability of i.MX51 boards. The 5:1 ratio we have in barebox
probably goes back to copy/paste from the i.MX53 code.

imx_silicon_revision() can't be used from early init context, so
use imx51_silicon_revision() instead.
Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
The IROM is located at physical address 0x0, so reading the
silicon revision from it leads to a NULL pointer dereference
if done too late when the MMU is already enabled. Use the IIM
instead which is also done in the Kernel. This limits the silicon
revisions to 2.0 and 3.0, but I assume the earlier versions are
not seen in the wild anyway.
This also moves the call to imx_set_silicon_revision() out of
imx51_silicon_revision() so that imx51_silicon_revision() can be called
in early init context.
