Currently, we only have DM_FLAG_ACTIVATED to indicate the device

binding or probing.
This commit introduces a new flag, DM_FLAG_BOUND, which is set when
the device is really bound, and cleared when it is unbound.

With devm_kzalloc(), device_unbind() and the failure path in
device_bind() can be much cleaner.
We no longer need such flags as DM_FLAG_ALLOC_PDATA etc. because
we do not have to remember if the memory has been really allocated.
The memory is freed when the device is unbind.

These two declarations in arch/x86/include/asm/interrupt.h conflict
with ones in include/linux/compat.h, so x86 boards cannot include

The comment /* arch/x86/lib/interrupts.c */ is bogus now, and we do

In U-Boot's driver model, memory is basically allocated and freed
in the core framework. So, low level drivers generally only have
to specify the size of needed memory with .priv_auto_alloc_size,
.platdata_auto_alloc_size, etc. Nevertheless, some drivers still
need to allocate memory on their

The output looks like
Currently, Devres requires additional 16 byte for each allocation,
which is not so insignificant for SPL in some cases.
If CONFIG_DM_DEVICE_REMOVE is disabled, we never remove devices,
so we do not have to manage resources in the first place.
In this case, devres_alloc() can fall back to the

Currently, kzalloc() returns zero-filled memory, while kmalloc()
