- remove read-write logic - this should be handled by radio protocol implementation
- remove EVENTS and TASKS bit definitions - we can just use a signle definition
- add more radio ops
- fix frequency configuration
- fix printf warnings
- fix radio reset

This patch revises `k230_hart.[ch]` by:
- revising big core boot/stop control.
- making k230_hart_is_big() available in S-mode.
- adding more comments.
This patch also revises the `ld-kernel.script` so that to match the
latest MMU pgtable design.

K230 chip has two T-Head C908 RiscV cores, previously we run NuttX
on either little or big cores. This patch runs NuttX on both cores
with OpenAMP support via the RPTUN driver.
New additions:
- in arch/risc-v/src/k230
- k230_rptun.c K230 RPTUN driver
- k230_rptun.h K230 RPTUN driver header file
- in baords/risc-v/k230/canmv230
- configs/master Build config for master node
- configs/remote Build config for remote node
- scripts/ld-rptun.script Build script for RPTUN
Major changes:
- arch/risc-v/Kconfig Select NUTTSBI_LATE_INIT upon NUTTSBI
- in arch/risc-v/include
- k230/irq.h Add UART3 IRQ defs
- in arch/risc-v/src/k230
- Kconfig Add RPTUN related config items
- Make.defs Add k230-rptun.c to sources
- hardware/k230_memorymap.h Add K230 device and CSR defs
- k230_hart.c Add hart ctrl for RPTUN
- k230_hart.h Add hart ctrl for RPTUN
- k230_mm_init.c Add Svpmbt to support RPTUN
- k230_start.c Revised to support RPMsg UART
- in boards/risc-v/k230/canmv230
- scripts/Make.defs Add RPTUN script selection
- src/canmv_init.c Add RPTUN and RPMsg_UART initialization
- in Documentation/platforms/risc-v/k230/boards/canmv230
- index.rst Add AMP usage information.

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.

SAMv7 reset controller stores the cause of last reset (SW reset, power up,
pin reset etc.) in status register. This commit adds function that allows
the board to retrieve this information. This function should be called
from board support layer either during initialization or based on
incoming ioctl call.
Adding the sam_get_reset_cause() to sam_systemreset.c also resulted in
always compiling this file by default and only putting up_systemreset()
under CONFIG_SAMV7_SYSTEMRESET option.
Also header file sam_systemreset.h was created as it defines reset types
in comfortable manner for future processing in board layer. This is done
to avoid passing boardctl dependent structure to architecture layer.

By setting "isconsole" to false, mpfs_serial stops outputting to console.
This can be used to disable output to debug console in low level.

It is possible that a PLIC IRQ is claimed but not completed at warm
reset. This occurs at least if there is a fault in the middle of irq
handler execution.
To recover from such situation, we can complete all IRQ:s in PLIC;
this completes any already claimed IRQ, but has no effect on IRQs
which are not claimed or not enabled.

- Use mpfs_i2c_deinit+mpfs_i2c_init sequence to re-initialize i2c block
- Use the i2c mutex to protect the reset; in case there are several devices
on the same bus, and one of them resets the bus, reset must not occur in
the middle of another device's transfer.
- Move irq attach to the i2c_init as the irq detach is in i2c_deinit

Ensure that there are no pending state or interrupts in the i2c controller. This removes
errors caused by deinitialize/initialize sequences in error cases.

Replace risky DEBUGASSERT()s with real sanity checks. Also,
do a few more checks as the system might occasionally fire an
interrupt if the system has been restarted while in middle of
an i2c transaction.
Yet, modify i2c_transfer() function so that up_disable_irq()
is always called at the end to better prevent ill-timed irqs.

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.
Current mmu_flush_cache() hook lacks the reg param which needed by
some targets. So this PR adds the param and update existing targets
using that hook.

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.
