04f81ecddb arch: risc-v: Do not enable FPU for K210 with QEMU 
Summary:
- I noticed that maix-bit:smp does not work with QEMU.
- Actually, QEMU supports sifive_u (not K210) but it works
  if FPU is disabled.
- This commit fixes this issue.

Impact:
- K210 with QEMU only

Testing:
- Tested with qemu-5.2

370152f3ba RISC-V: Move mhartid to own assembly macro+function 
Hartid and cpuindex are not the same thing. Hartid is needed regardless
of SMP, for external interrupt handling etc.

SMP needs cpuindex which might not be index == hartid, so both are
needed. IMO it is clearer to provide separate API for both.

Currently the implementation of up_cpu_index is done a bit lazily,
because it assumes hartid == cpu index, but this is not 100% accurate,
so it is still missing some logic.

Now the dynamic linker parses the constructors/destructors information
from the DYNAMIC segment of the program.

e6d6734db2 ARCH_ADDRENV: Add guard against mis-configuration 
When process a is switched to process b, the address environment is
swapped with a call to group_addrenv(). The stack upon entry will be
a's, and upon exit b's. This will fail, so a neutral stack is required,
either a kernel stack or an IRQ stack.

Infrastructure for an IRQ stack is already in place, so give a hint
that an interrupt stack should be provided if address environments
are enabled.

4456b13c19 riscv/bl602: Remove check for LCD driver 
## Summary

`bl602_spi_cmddata()` implements SPI Cmd/Data `SPI_CMDDATA()` for only 3 LCD drivers: ST7735, ST7789 and GC9A01.

This patch removes the check for LCD drivers, so that SPI Cmd/Data will work for all LCD drivers.

More details: https://github.com/apache/incubator-nuttx/pull/5898

## Impact

This change impacts LCD drivers that call `SPI_CMDDATA()`.

Previously `SPI_CMDDATA()` would fail with `ENODEV` for LCD drivers other than ST7735, ST7789 and GC9A01.

After patching, `SPI_CMDDATA()` will work correctly with all LCD drivers.

## Testing

We tested with LVGL and ST7789 on PineCone BL602:

-   [Testing with LVGL](https://github.com/lupyuen/st7789-nuttx#run-lvgl-demo)

As for regular SPI Devices that don't require SPI Cmd/Data, we tested `CONFIG_SPI_CMDDATA=y` with Semtech SX1262 SPI Transceiver on PineCone BL602:

The SPSR is used to store the current value of the CPSR when an exception
is taken so that it can be restored after handling the exception.
Each exception handling mode can access its own SPSR.

User mode and System mode do not have an SPSR because they are not
exception handling modes.

4f885fe6bf riscv/bl602: Implement SPI Cmd/Data 
## Summary

To control the Data/Command Pin on ST7789 SPI Display, the SPI Driver flips the MISO Pin as though it was a GPIO.

To implement this on BL602, we reconfigure MISO from SPI Pin to GPIO Pin on the fly inside `bl602_spi_cmddata()`.

When the SPI Port is deselected (after the SPI operation), we revert MISO back from GPIO Pin to SPI Pin. We implement this inside `bl602_spi_select()`.

[More Details Here](https://github.com/lupyuen/st7789-nuttx#spi-cmddata)

## Impact

This change impacts 3 LCD drivers that call `SPI_CMDDATA()`: ST7735, ST7789, GC9A01.

Previously the BL602 SPI Driver would fail with "SPI cmddata not supported" when the above drivers are used.

After the change, the above drivers will set the LCD Data/Command Pin correctly.

## Testing

We tested this implementation of SPI Cmd/Data with NuttX ST7789 Driver and a Logic Analyser on PineCone BL602:

c67272f9c8 riscv/bl602: Enable SPI Master in SPI Poll Send 
## Summary

SPI Poll Send `bl602_spi_poll_send()` doesn't send any SPI Data because it doesn't enable SPI Master and it doesn't clear the SPI FIFO. Also it hangs because it loops forever waiting for the FIFO.

We fix this problem by moving the code that enables SPI Master and clears the FIFO, from SPI Poll Exchange `bl602_spi_poll_exchange()` to SPI Poll Send. (Note that SPI Poll Exchange calls SPI Poll Send)

[More Details Here](https://github.com/lupyuen/st7789-nuttx#fix-spi-send)

## Impact

This problem affects all NuttX Drivers that call `SPI_SEND()` on BL602, including the ST7789 Display Driver.

Previously `SPI_SEND()` didn't send any SPI Data and never returns, because it loops forever waiting to receive data.

Now `SPI_SEND()` sends data and returns correctly.

[More Details Here](https://github.com/lupyuen/st7789-nuttx#fix-spi-send)

## Testing

We tested the modified SPI Poll Send with NuttX ST7789 Driver and a Logic Analyser on PineCone BL602:

    arch/arm: optimize context switch speed

    The current context save implementation saves registers of each task
    to xcp context, which is unnecessary because most of the arm registers are
    already saved in the task stack, this commit replace the xcp context with
    stack context to improve context switching performance and reduce the tcb
    space occupation of tcb instance.

ce8fae2842 xtensa_coproc.S: Adjust the save reserved for local variables when 
restoring/saving coprocessor state.

These function don't use call8 or call12 and thus need to create just 16
bytes for the base save area, however they do use one variable so we
need a space for that.  The `entry` instruction works in unit of 8 bytes
so we add whole 8 bytes for one variable.
