b3baf95835 UMM: Implement getter for address environment heap start vaddr
Using the Kconfig macro does not work for RISC-V target, as there the
user heap follows .data/.bss and does not obey any Kconfig provided
boundary.

1322f82802 RISC-V: Copy kernel memory mappings to userspace addrenv
Copy the kernel mappings to the new (user) address environment. The
copyuing is done exactly once. This relies on the fact that the kernel
L1/L2 mappings will never change, as all of the kernel memory is mapped
upon boot.

57127b9429 RISC-V: Initial support for CONFIG_BUILD_KERNEL
This implements initial support for kernel build (address environments,
page allocator) for RISC-V.

This is done a bit differently compared to the ARMV7 implementation:

- Support implemented for Sv39 MMU, however the implementation should be
  extensible for other MMU types also.
- Instead of preserving and moving the L1 references around, a canonical
  approach is used instead, where the page table base address register
  is switched upon context switch.
- To preserve a bit of memory, only a single L1/L2 table is supported,
  this gives access to 1GiB of virtual memory for each process, which
  should be more than enough.

Some things worth noting:
- Assumes page pool is mapped with vaddr=paddr mappings
- The CONFIG_ARCH_XXXX_VBASE and CONFIG_ARCH_XXXX_NPAGES values are
  ignored, with the exception of CONFIG_ARCH_DATA_VBASE which is used
  for ARCH_DATA_RESERVE
- ARCH_DATA_RESERVE is placed at the beginning of the userspace task's
  address environment

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.

ff210e1c2d arch/stack_color: correct the end address of stack color
The different optimization of compilers will cause ambiguity in
obtaining sp through up_getsp() in arm_stack_color(), if compile
with clang and enable the optimization flag (-Ofast), up_getsp()
call will be earlier than push {r0-r9,lr}, the end address of color
stack will overlap with saved registers.

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:

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:

-   [Testing with Logic Analyser](https://github.com/lupyuen/st7789-nuttx#spi-cmddata)

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:

-  [Testing with Logic Analyser](https://github.com/lupyuen/st7789-nuttx#fix-spi-send)

We also tested LVGL with ST7789 on PineCone BL602:
