Prior to that, seeing the debug() messages required to enable DM_DEBUG
which defines DEBUG (and then _DEBUG) which in turn makes failing
assert() calls reset U-Boot which isn't necessarily what is desired.

Instead, let's migrate to dm_warn which is using log_debug when unset or
log_warn when set.

While at it, reword the DM_DEBUG symbol in Kconfig to explain what it
now actually does.

outp always point to an unsigned type in ofnode_read_u* functions but
the format specifier is currently always using signed type.

This is an issue since the signed type can only contain half of the
unsigned type values above 0.

However, this now breaks another usecase. Indeed,
ofnode_read_s32_default is actually passing an s32 but it'll be printed
as a u32 instead. But since the function is called u32, it makes more
sense to have it print an unsigned value.

This was discovered because arm,smc-id = <0x82000010>; on RK3588S is
above the max signed value and therefore would return a negative signed
decimal value instead of its proper unsigned one.

As part of bringing the master branch back in to next, we need to allow
for all of these changes to exist here.

When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay
Ethernet"' I failed to notice that b4 noticed it was based on next and
so took that as the base commit and merged that part of next to master.

This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing
changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35.

Remove <common.h> from this driver directory and when needed
add missing include files directly.

Check the header before starting to use it, since this could provide
very confusing later, when ofnode calls start to fail.

The baudrate configured in .config is taken by default by serial. If
change of baudrate is required then the .config needs to changed and
u-boot recompilation is required or the u-boot environment needs to be
updated.

To avoid this, support is added to fetch the baudrate directly from the
device tree file and update.
The serial, prints the log with the configured baudrate in the dtb.
The commit c4df0f6f315c ("arm: mvebu: Espressobin: Set default value for
$fdtfile env variable") is taken as reference for changing the default
environment variable.

The default environment stores the default baudrate value, When default
baudrate and dtb baudrate are not same glitches are seen on the serial.
So, the environment also needs to be updated with the dtb baudrate to
avoid the glitches on the serial.

Also add test to cover this new function.

The PCI helpers read only the base address for a PCI region. In some cases
the size is needed as well, e.g. to pass along to a driver which needs to
know the size of its register area.

Update the functions to allow the size to be returned. For serial, record
the information and provided it with the serial_info() call.

A limitation still exists in that the size is not available when OF_LIVE
is enabled, so take account of that in the tests.

Add support for writing a single 64-bit value into a property.

Repurpose the existing tests to handle this case too.

Signed-off-by: Simon Glass <sjg@chromium.org>

Add functions to write a boolean property. This involves deleting it if
the value is false.

Add a new ofnode_has_property() as well. Add a comment about the behaviour
of of_read_property() when the property value is empty.
