state: backend_bucket_circular: fix for non power of 2 writesize ...

backend_bucket_circular currently assumes writesize is power of 2,
which makes it fail on dataflash devices, where this assumption
is false.

bootsource: handle SPI-NOR in the same way as SPI-EEPROM ...

The NOR flash device itself does not have an alias in the kernel DT, so

block: Do not ignore error in blk->ops->write() ...

Getting a error from blk->ops->write() is not a very unlikely
event (happens quite often during new board bringup), so we need to
catch and propagate them to upper layers so they can be at least
reported properly. Change the code of all of the callers to bail out
as soon as blk->ops->write() fails.

common: clock: Sample time before poller_call() ...

Change is_timeout() to sample current time before invoking poller
infrascructure to avoid occasional false timeout conditions.

Consider the following timeout loop (can be found in wait_on_timeout):

        while (!(condition)) {
	        if (is_timeout(...)) {
	       	        return -ETIMEDOUT;
                }
        }
	...

in the original logic of is_timeout() it was possible to end up in the
following situation:

        1. Immediate check of of "condition" yeilds false (not enough
           time for it to become true has passed yet)

	2. is_timeout is called which, in turn, calls poller_call()

	3. All registerd pollers take more than specified timeout time
	   to execute.

	4. Sometime during poller_call() "contition" becomes true

	5. As a result of #3 is_timeout() returns "true"

	6. Code bails out with -ETIMEDOUT early even though timeout
	   condition didn't really occur.

One concrete example of this problem was discovered on ZII RDU1
board (poller_call() is long due to a serdev) when doing large data
transfers over SPI to attached DataFlash chip.

This commit changes is_timeout() to sample the value of time before
calling poller_call(). This way first call to is_timeout() will almost
always return false thus checking the condition at least twice before
declaring a timeout.

putc_ll doesn't do newline conversion (and it shouldn't do, as it's

it uses putc_ll for printing early messages.

bootm: Split bootm_load_devicetree into two functions ...

It is not always desired to get the devicetree from image data and load
it to a SDRAM region at the same time. Sometimes it's enough to just
load it to an allocated address (in case the user has no constraints
where the devicetree should be placed.

This patch splits bootm_load_devicetree into bootm_get_devicetree which
returns a pointer to the allocated devicetree and bootm_load_devicetree
which loads the devicetree to a specified region.
