This driver is used with QEMU, to make it possible
to use networking.
This is not the MAC in ESP32, however, it can be used with QEMU.
The code was shamelessly copied from 31dac92e5f
Because the ratio between API value and ISX019 register value
is 128 : 90 about HUE, some different API values become the
same register value.
So, store the value specified by application in setting,
and return the stored value in getting so that the gotten value
is the same as the setting value by application.
About IMGSENSOR_ID_EXPOSURE_AUTO, IMGSENSOR_ID_ISO_SENSITIVITY_AUTO,
and IMGSENSOR_ID_EXPOSURE_METERING, enumerations are defined.
So, control type should be not integer but integer menu.
About parameter whose register size is less than 4 bytes,
when transfer read value to API parameter, cast appropriately
to avoid the following problems.
- Read value includes garbage value
- Negative value becomes huge positive value
Modify control id definition to avoid duplication even if
the control ids belong to the same control class.
Also, not refer to control class in driver.
This fixes calls like memmem("hello", 5, "lo", 2);
Also zero-length needle is deemed to exist at beginning of haystack.
This behavior matches memmem() on Linux, FreeBSD, NetBSD and OpenBSD.

The delete flag is not synchronized with the life cycle of the group,
if the flag set before waitpid(), the tcb will be mistakenly deleted
by group_del_waiter(), use-after-free will happen.

This patch adds rv64 targets support and checked with gdb-multiarch
on Ubuntu. It also marks `-arch` parameter optional as it often can
be learnt from ELF file.

This patch simplifies PMP handling for K230 using common APIs.
It also uses `g_misa` variable to expose the MISA issue.

check if interrupt is busy when IRQCHAIN is disabled
this allows user to catch configuration errors and fail early when the
already busy vector is reused
