The current implementation may cause BUG_ON() in blkfront_aio()
BUG_ON(n > BLKIF_MAX_SEGMENTS_PER_REQUEST);
In pvblock_iop(), a read/write operation will be split into smaller
chunks of data so that the size in one access (aio_nbytes) is limited
to, at the maximum,
BLKIF_MAX_SEGMENTS_PER_REQUEST * PAGE_SIZE
But this works only if when the *buffer* passed in to pvblock_io()
is page-aligned. If not, the given data region may stand across
(BLKIF_MAX_SEGMENTS_PER_REQUEST + 1) pages. See the logic in
blkfront_aio():
start = (uintptr_t)aiocbp->aio_buf & PAGE_MASK;
end = ((uintptr_t)aiocbp->aio_buf + aiocbp->aio_nbytes +
PAGE_SIZE - 1) & PAGE_MASK;
Then this will lead to BUG_ON() above.
This can be fixed by decreasing the maximum size of aio_nbytes.

Currently the "clock-frequency" DT property is only being considered as an
fallback if either there is no clock driver, the clock driver implements
the request-op correctly or there is no clock defined for the timer at all.
This patch makes "clock-frequency" also being picked as a fallback if
getting the clock-rate fails, since clk_get(_by_index) will return no
error, if a clock driver does not implement the request-op and does also
not support getting the rate of the clock in question.
timer_post_probe will take care if the property does not exist in the DT or
is defined as 0.

To quote the author:
The show_board_info() function was adjusted to weak so that it could be
entirely replaced with a board-specific implementation.
The intended way for boards to provide their own information is via a
sysinfo driver. But currently there is no way to show anything other
than the model name.
This series adds support for showing a few more items, in a way that is
easy for boards to extend.
Since there is already a weak checkboard() function, we don't need to
have two levels of weak function here. So this series drops the weak
attribute from show_board_info()
Existing boards will see a slight change in output, in that the model
name will appear first, before any custom output. If that is a problem,
then the solution is to implement a sysinfo driver for the board.
At present only the model name is shown on start. Some boards want to
display more information. Add some more options to allow display of the
manufacturer as well as the version and date of any prior-stage
firmware.
This is useful for coreboot, at least. If other boards have more
information to display, it is easy to add it, now.
