crypto: caam: use dma_alloc_coherent instead of dma_alloc ...

dma_alloc return non-coherent memory, but the driver does no cache
maintenance on the buffer, causing memory corruption. Fix this by
requesting coherent memory for the DMA transfer.

According to the Errata ERR004346 (WDOG: WDOG SRS bit requires to be written

Without this two additional writes, the system will not reset always.

sandbox: fix registering multiple consoles ...

Consoles need to be registered with the "console" device name so that
they are probed by the correct driver. The barebox_register_console()
was already forcing this as it was overwriting the name that was being
passed as argument, but it was failing to provide a unique id for
each new console, so the underlying register_device() would just
return an error when wanting to re-register a device with device name
"console" and id 0.

We remove the unused name parameter from barebox_register_console() as
it is really nowhere used, and also specify DEVICE_ID_DYNAMIC as id,
so that a new unique device id is given to each newly registered
console device.

usb: imx: Only use clock when it exists ...

Fixes: bbe0df9

I assumed all chipidea devices actually have a clock. This is true
when looking at the device tree, but in barebox not all i.MX SoCs
use the clocks provided by the device tree. Most instead use
clkdev_add_physbase() to attach a clocks to devices. For these the
chipidea device does not have a clock.

mtd: nand_omap_gpmc: fix BCH error correction ...

BCH error detection and correction was only looking at the first
of four syndrome polynomials, which meant it was failing to detect
and correct bitflips in the last 3/4 of the data. In effect, only
the first 512 bytes of a 2048 byte page were being protected by ECC.

The syndrome polynomials (BCH error codes) are stored in the NAND's
OOB, each of which protects 512 bytes of data. The driver used
eccsteps = 1 which effectively made it only use the first polynomial,
and therefore was only protecting the first 512 bytes of the page.

The fix is to pull over a bit of code from the kernel's
omap_correct_data() that sets eccsteps = 4 when the page size is 2048
bytes and hardware ECC is being used.
