The enumeration process for composite and non-composite devices
has a lot of duplicate code. Treating the code for composite
devices as universal enumeration code can reduce redundant code.

Add documentation referring to sim:alsa defconfig, about how to
mount host system files in the simulator using `hostfs` and
playing them using the ALSA adapter.

This provides the initial hooks for Flattened Device Tree support
with QEMU RV. It also provides a new procfs file that exposes the
fdt to userspace much like the /sys/firmware/fdt endpoint in Linux.
See https://www.kernel.org/doc/Documentation/ABI/testing/sysfs-firmware-ofw
Nodes in the fdt are not yet usable by the OS.

For TEE & REE, securefault & busfault are not banked, so the faults can
only forword to TEE/REE.
But how to crash dump the other core which not handled faults ?
Here we provide a way to resolve this problem:
1. Set the securefault & busfault to TEE
2. busfault happend from TEE, then directly dump TEE
3. busfault happend from REE, then generate nonsecurefault
4. Back to REE, and dump

replace *(.init_array .init_array.*) with KEEP(*(.init_array .init_array.*)).
The KEEP statement within a linker script will instruct the linker to keep the specified section, even if no symbols inside it are referenced. This statement is used within the SECTIONS section of the linker script. This becomes relevant when garbage collection is performed at link time, enabled by passing the --gc-sections switch to the linker. The KEEP statement instructs the linker to use the specified section as a root node when creating a dependency graph, looking for unused sections. Essentially forcing the section to be marked as used.

FlexCAN before used interrupts to process incoming frames.
This patch adds a HPWORK workqueue to process incoming frames in the workqueue
context instead. Also renamed mbi to txmb for better readability.
ni_buffer is defined in the initialized structure, put it in the data segment, it will increase the flash size

This introduces non-generic option interface for IO expanders.
Some IO expanders have more advance options for pins and communication.
This is used to pass driver dependend structure to expander driver.

unbind will call the adb_char_on_connect interface to wake up the adbd task,
adbd will then access the adb device and fail to return, at this time it will
close the adb device, we can do the final memory release operation in the
second unbind

* Error handling for abnormal interrupts and DMA errors is now
enabled for all builds, regardless of any DEBUG configuration.
* Error handling resets the MAC for the specific errors that
may halt the Ethernet operation, instead of everything as it
was before.
