We call phy_update_status only once in 5 seconds. This makes
sure we do not have great overhead when using ethernet devices.
However, if phylib tells us the link is down anyway, there won't
be ethernet transfers, so it doesn't hurt to call phy_update_status
in this case. This makes sure we can use the ethernet device when
the link comes up and do not have an additional 5 second penalty
in this case.

Some phys come up with this bit set, clear it so that these phys
can work. This has been observed with a ASIX compatible USB ethernet
adapter.

omap3 has a soc specific reset function, make sure it calls common_reset
so that the proper CPU flags are set.

We allow unaligned accesses on ARMv6 onwards, make sure the CR_A
flag is cleared so that unaligned accesses do not trap.

The fec has multiple clock inputs:
- 50MHz clock for generating the (R)MII clock
- bus clock
The MDIO clock is derived from the bus clock, not the 50MHz clock,
so pass this into the driver so that it can correctly configure
the MDIO clock divider.
This fixes several wrong MDIO register read problems on i.MX28 boards.

This adds the glue code for the i.MX SATA controller. This controller
needs some i.MX specific setup and some SoC specific setting outside
the controller itself. The code for setting up the correct clock source
for the SATA phy has been taken from U-Boot.

This adds ahci controller support based on U-Boot ahci support. Unlike
U-Boot we do not push the SCSI layer in between, but use the ata interface
directly. Tested on a Freescale i.MX53.

ATA devices using DMA may need a sufficiently aligned buffer, so use
dma_alloc instead of regular malloc.

Currently we only support oldschool IDE SFF devices. This is done
by registering a register layout struct and everything else is done
by the generic IDE SFF driver. Since modern ATA devices still use
ATA, but not the SFF interface anymore, split out the IDE SFF support
to a separate file to allow for other types of ata interfaces.

Using /dev/disk* for every type of device is not helpful. It increases
the chance that the user doesn't know which file corresponds to which
device. So rename ata device files to /dev/ata*. Also add a dev_info
about which device just has been registered.

mtd->write is supposed to loop around pages internally, no need
to do this in mtd_write. This fixes a huge write performance drop
with the m25p80 driver when it was converted to a mtd driver recently.
Since mtd->writesize is 1 for this driver mtd_write ended up doing
single byte writes on the flash.

The nand layer handles partial page writes just fine. If the start or
end of the data is not page aligned, the nand layer will copy the data
to a temporary page buffer.
Remove the check which disallows partial page writes since this is what
we want to do on barebox when for example an image is written to nand
which is not padded to page size.
