arch/arm/src/stm32/hardware/stm32g47xxx_memorymap.h:
* STM32_OPTION_BASE: The comment incorrectly said the range was
0x1fff7800-0x1fff780f for a total of 16 Option Bytes. Corrected
this to 0x1fff7800-0x1fff782f, as the device has 48 Option Bytes
for this option block.
* STM32_OPTION_BASE2: The comment incorrectly said the range was
0x1ffff800-0x1ffff80f for a total of 16 Option Bytes. Corrected
this to 0x1ffff800-0x1ffff82f, as the device has 48 Option Bytes
for this option block.
Summary:
- This commit improves SPI performance.
- For small data, it does not use DMA.
Impact:
- All use cases which use SPI with DMA
Testing:
- Tested with spresense:wifi and spresense:example_lcd

Summary:
- This commit fixes IRQ control for the following use case
- The gs2200m Wi-Fi driver requests SPI-DMA to receive a packet.
- cxd56_dma.c enables IRQ for the SPI-DMA and start transfer.
- Then LCD driver requests SPI-DMA to display an image.
- These SPI-DMAs use different DMA channels but share the DMA controller.
- Also, they share the same IRQ.
- When the first SPI-DMA finishes the transfer, it disables the IRQ.
- And if the second SPI-DMA finishes the transfer just after the IRQ disabled.
- The second SPI-DMA will be in a deadlock condition.
- To resolve this issue, do not control IRQ during DMA transfer.
- Instead, up_enable_irq() is called in up_dma_initialize()
Impact:
- All use cases which use DMA
Testing:
- Tested with spresense:wifi with LCD

Summary:
- This commit adds SMP support to cxd56_farapi.c
- nxplayer now works in SMP mode
Impact:
- Spresense in SMP mode only
Testing:
- Add the following configs to spresense:wifi
- +CONFIG_SCHED_INSTRUMENTATION=yy
- +CONFIG_SCHED_INSTRUMENTATION_BUFFER=y
- +CONFIG_SMP=y
- +CONFIG_SMP_NCPUS=2
- +CONFIG_SPINLOCK_IRQ=y
- Run nxplayer and play an WAV file on uSD card
- NOTE: http streaming playback would cause deadlocks
