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
this partly revert 4123615621 which works OK for PCI serial and network cards
but breaks QEMU EDU due to usage of sem and usleep in IDLE thread context.
Another solution will be provided later.

When an application is being loaded `up_addrenv_create ` calls
`create_region` to create the address environment. Only the first
entry is mapped when the region is created. Virtual memory that is
not mapped will trigger an exception when accessed. Other memory
pages are allocated and mapped on-demand. This enables setting
larger heap and stack for the process without compromising the
overall system memory.
Current `CONFIG_PAGING` refers to an experimental implementation
to enable embedded MCUs with some limited RAM space to execute
large programs from some non-random access media.
On-demand paging should be implemented for the kernel mode with
address environment implementation enabled.
We will first check whether the target file path exists. If it does not exist, we will check whether the common exists. If not, we will restore the path that should be spliced at the beginning.

We'll look for ETC resources from two paths
1.board/src/etc
2.common/etc
Search for the content in the board/src/etc directory first

Previously we need turn off the PMP locks in K230 vendor u-boot to use
NuttX, this complicates the setup process. This patch supports running
NuttX with original vendor u-boot so that to reduce setup complexity.
It also enables empty NSH prompt string in AMP master config as the apps
side support is ready.

DEBUG_FULLOPT enables many x86 related optimizations which can
be broken in many ways (eg. not aligned stack).
With this change it's easier to catch changes that breaks x86_64.

Align _ebss to 16, otherwise g_idle_topstack is not correctly aligned.
For some reason the previous alignment worked with make buit but in case
of cmake with optimization enabled, the IDLE stack was misaligned which
caused vector instruction misalignment exception.

This patch update documents to reflect the fact that remote node is kicked
off by master node. It also adds debug dump to aid the MISA reading issue
investigation.

Add support for tricore TC397
1. Porting based on AURIX TC397 KIT_A2G_TC397_5V_TFT evaluation board
https://www.infineon.com/cms/en/product/evaluation-boards/kit_a2g_tc397_5v_tft/
2. In order to avoid license and coding style issues, The chip-level code
still uses the implementation of AURIX Development Studio SDK.
The SDK package will be downloaded as a third-party package during compilation:
https://github.com/anchao/tc397_sdk
3. Single core only, SMP implementation will be provided in the future.
4. Implemented the basic System Timer, ASCLIN UART driver.
5. Only the Tasking tool chain is supported (ctc/ltc, license maybe required)
6. 'ostest' can be completed on the TC397 development board.
How to run?
1. Setup the tasking toolchain and license
$ export TSK_LICENSE_KEY_SW160800=d22f-7473-ff5d-1b70
$ export TSK_LICENSE_SERVER=192.168.36.12:9090
2. Build nuttx ELF
$ ./tools/configure.sh tc397/nsh
$ make -j
...
artc I800: creating archive libc_fpu.a
LD: nuttx
3. Switch to windows PC, setup AURIX-studio to Debugger Launcher
4. Replace runing ELF to nuttx, and re-download ELF
