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.

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

I recently imported NuttX version 6.0 (and nsh) into a Microchip
Studio project [1] on Windows to figure out what was going wrong with
the avr32dev1 build. I also briefly checked NuttX version 10.
I worked with the assumption that the avr32 (avr32dev1) specific
changes to the codebase were minimal across NuttX releases.
For the initial proof of concept I used Microchip Studio version 7.0
(with the recent Microchip's ASF updates). I use avr32-gcc (4.4.7)
hosted here [2] for building NuttX for avr32dev1 on GNU/Linux.
Even with the Microchip Studio project, I had initial debug problems
with just stepping through the code a line at a time. I had to bring
in crt0, a trampoline stub and the linker file from one of my older
projects to really build on the suspicion I had with the linker file.
Perhaps an older version of avr32-gcc did something differently. I am
not sure about this. I used avr32-objdump to see the output sections
of the generated elf file. I just had to tweak the linker script to
ensure correct linking of the sections.
With those changes, I was able to inspect the UART sections within
NuttX Microchip Studio project.
Second important change: the transmit pin: I had to reassign the pin
to see the nsh console.
These are the currently assigned UART pins:
RX: PA_24 -> Physical IC pin 59
TX: PB_02 -> Physical IC pin 24
For the avr32dev1 board, they are pins: J1 (berg pin 28) and J2 (berg
pin 10).
In addition, the PR fixes silly compilation problems with avr32dev1.
I have tested the nsh build with my avr32dev1 boards. I used Atmel ICE
to program one of them (flash at 0x80000000) and dfu-programmer to
test my other board (flash at 0x80002000). The other RS-232 parameters
are the same as they were.

As long as the GNSS feature is not used, GNSS RAM can be used as general memory.
This memory is 640KByte total, which is lower performance than the application RAM.
It is possible to locate text, data and bss into GNSS RAM and to use as heap area.
Since there were some cases in which the current modem reset
sequence did not reset the modem, the reset was ensured by
executing power off and power on of the modem.
Enable with ./tools/configure.sh -l esp32-devkitc:dac
DAC channel 0 = GPIO 25
DAC channel 1 = GPIO 26
default path: /dev/dac0
Resolution 8 bits = values 0~255
Voltage: 0~Vref
The reference voltage 'Vref' here is input from the pin VDD3P3_RTC
which ideally equals to the power supply VDD (3.3V).
Weak function sometimes can't have strong implementation linked.
This patch uses NUTTSBI_LATE_INIT config and normal function instead
to avoid those issues.
