@danielappiagyei-bc Great! - The residual change needs to be applied the S32K, and K66

Hi @davids5 , I've now applied these changes to the S32K devices but couldn't find a "k66", could you point me to the file?
Also I didn't enable an interrupt for overruns on these S32K devices, would you like me to? Thanks

Sorry I called it by name not family https://github.com/apache/nuttx/blob/master/arch/arm/src/kinetis/kinetis_edma.c

So strike this. See #10912 (comment)

You might want to rebase on master after #11020 comes in and bring in all the other bits not related to serial or DMA

Thanks david, I will close this PR and create a new one for the leftover changes. This will be:

• typos
• adding IMXRT_SERIAL_RXDMA_BUFFER_SIZE as a kconfig
• add missing uintptr_t base; declaration to arch/arm/src/imxrt/imxrt_edma.c so compiling with CONFIG_DEBUG_DMA=y works
• enabling LPUART_CTRL_ORIE for overruns in arch/arm/src/imxrt/imxrt_serial.c. It's an error condition just like the noise, framing, and parity error interrupts we have enabled and we are already explicitly clearing it in here

Per david, he has found the cause to the issue and is fixing in his PR. See #10911 (comment) for what I will add in followup PR
