G4 LPUART rework

[DieHertz]

This PR contains changes from #11786 as it's somewhat related (touches the same places), I will remove them once it's merged.

Substantial changes are the ones related to UART DMA and IRQHandlers:

• there were no IRQHandlers defined for UART10 and LPUART1.
• static uartDmaopt_t uartDmaopt[] had no entry for LPUART1
• UARTDEV_CONFIG_MAX = 8 did not take neither UART10 nor LPUART1 into account

Tested on my G4 board made by Airbot

@haslinghuis both LPUARTDEV_1 and SERIAL_PORT_LPUART1 are target-agnostic and therefore defined for all targets, not sure what you're asking to change here.

I'm waiting for the other PR to get merged before any fixes in this one anyway

It fails for a different reason, looks like the file which includes and uses this Macro does not include serial_uart.h. It would fail on a UARTDEV_1 as well.

Hi,

would be great if this could be merged :)

[haslinghuis]

Besides rebase build is failing so needs some work after merge of #11786

G4 samples are on their way for development.

[haslinghuis]

@DieHertz hope you don't mind. Have rebased this work and fixed the macro for non LPUART boards

[haslinghuis]

LPUART is showing but SOFTSERIAL not.

Do you want to test this code? Here you have an automated build:

WARNING: It may be unstable. Use only for testing! See: https://www.youtube.com/watch?v=I1uN9CN30gw for instructions for unified targets!

[haslinghuis]

For 4.4 we need: betaflight/unified-targets#989
For 4.5 we need: #12705

I'll review in more details once #11786 is merged and this is rebased.

See #11786 (comment)

Tested on my new g4 airbot aio works good

@KarateBrot @SteveCEvans please review #11786

Softserial users who upgrade firmware from versions before this PR, and who restore their previous settings by diff or preset->save/restore, will find that they lose soft serial.

If soft serial was previously configured to serial TX 11, an older diff would include a line in the form:

resource SERIAL_TX 11 Ann

Where Ann means the pin designator, eg something like resource SERIAL_TX 11 B01

After this PR, this line should be reverted with

resource SERIAL_TX 11 NONE

And a line should be added, in the form:

resource SOFTSERIAL_TX 1 Ann

but with the same pin designator as before, eg resource SOFTSERIAL_TX 1 B01

[haslinghuis]

@ctzsnooze this has nothing to do with this PR.

Rename was done in #12679 but only applies to config.h. Before that it was changed from SERIAL to UART.

Sorry.
It was #11786 that caused the problem for me.
It only happened in the last few days, and #11786 was merged two days ago.
