The hardware timings for SWITCH_RESET at power-up might not be
sufficient for a proper reset, so let's make sure we put the switch into
reset for at least 10ms (80E6063 requirement) during the boot-up
sequence.
(somehow barebox-state resolves to the entire EEPROM, not the partition
with its offset, so let's move the partition to the start to make sure
barebox and linux agree about this)
This solves a problem which causes boot failure when using a uImage with
device tree. It should also speed up boot because the kernel can skip
copying itself out of the way.

The partition layout is board-specific, so only the barebox partitions
need to be in the fixed location expected by the MLO code.

We need to wait some time between activating the ethernet and
being able to send the first frame. I have not investigated why
that is the case.
Fixes: SYS#488
As this is the bootm image handler implementation for the kwbootimage
it is of no use if BOOTM is missing and fails to link.

The wdog1 pinctrl got fixed with linux upstream commit 213e51ca8df1 ("ARM:
dts: imx7: Add "LPSR" to LPSR iomux pin names").
Remove the old workaround, since it triggers a build error.

fsl,imx7d-iomuxc is provided by selecting PINCTRL_IMX_IOMUX_V3. Select it
since a system without it will not be very usefull.

As stated in the routine's description this routine is to return void,
hence fix its declaration to remove compiler warning.

Move PIT driver code to 'drivers/clocsource' and accomodate it by
adjusting Kconfig variables. Rename the file to 'timer-atmel-pit.c' to
re-align the driver with code in Linux kernel.

if not set, barebox will use first console by default.
On this board first console is KEYBOARD_GPIO, so we will end
in unusable state.

The CPU write buffer needs to be coherent with the cache, otherwise
we might flush stale entries with the actual data stuck in the cache.
This is really important on newer CPU core with bigger write buffers.

The ARMv6 K/Z derivatives have a v7 compatible MMU, but all other parts
(including the cache handling) is still at v6. As we don't make use of
the more advanced features of the v7 MMU in Barebox, it's okay to just
override this to properly identify the CPU as ARMv6.
