I couldn't find any buyable product other than reference boards using
TX49xx CPUs. And since nobody showed interest in keeping support for
it, it's time to remove it.

I've split up the removal into seperate parts for different maintainers.
So if the patch fits your needs, please take it via your tree or
give me an ack so I can apply them  the mips-next tree.

Thomas Bogendoerfer (10):
  MIPS: TX49xx: Drop support
  net: tc35815: Drop support for TX49XX boards
  net: 8390: Drop support for TX49XX boards
  spi: txx9: Remove driver
  dma: tx49 removal
  mtd: Remove drivers used by TX49xx
  char: hw_random: Remove tx4939 driver
  rtc: tx4939: Remove driver
  ide: tx4938ide: Remove driver
  ASoC: txx9: Remove driver

[04/10] spi: txx9: Remove driver
        commit: 74523a5dae0c96d6503fe72da66ee37fd23eb8f5

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark

I have an RBTX4927 development board in my board farm, boot-test every
bi-weekly renesas-drivers release on it, and fix kernel issues when they
appear.

Is that sufficient to keep it?

TX49xx SoCs were used in Sony LocationFree base stations, running
VxWorks. You can no longer buy them.
I'm not aware of anyone ever porting Linux to them.

>   spi: txx9: Remove driver

I only noticed the planned removal when I saw the SPI patch was applied.
Doesn't matter for me, as SPI is only present on TX4938, not on TX4927 ;-)

Gr{oetje,eeting}s,

It have been about 10 years since last time I see any TX49 board :-)

AFAIK Geert is the last user of TX49 SoC.
I'm OK with whole TX49xx (and TX39xx) removal if Geert (or any other
users) agreed.

for me it is. But now we probaly need some reverts then...

I wonder whether you have seen my mail about the removal

https://lore.kernel.org/linux-mips/20201207105627.GA15866@alpha.franken.de

and my call for people owning MIPS machines

https://lore.kernel.org/linux-mips/20200227144910.GA25011@alpha.franken.de/

Still "unclaimed" machines are

IMG Pistachio SoC based boards (MACH_PISTACHIO(
Toshiba TX39 series based machines (MACH_TX39XX)
NEC VR4100 series based machines (MACH_VR41XX)
Netlogic XLR/XLS based systems (NLM_XLR_BOARD)
Netlogic XLP based systems (NLM_XLP_BOARD)
Sibyte BCM91120C-CRhine (SIBYTE_CRHINE)
Sibyte BCM91120x-Carmel (SIBYTE_CARMEL)
Sibyte BCM91125C-CRhone (SIBYTE_CRHONE)
Sibyte BCM91125E-Rhone (SIBYTE_RHONE)
Sibyte BCM91250C2-LittleSur (SIBYTE_LITTLESUR)
Sibyte BCM91250E-Sentosa (SIBYTE_SENTOSA)

Is there something on this list you also regulary use ?

Thomas.

Indeed. Fortunately not all of it, as some removals were TX4938-only.

Sorry, I'm not following the linux-mips list that closely, so I hadn't
seen them.  It's always a good idea to CC linux-kernel, and perhaps the
few people who last touched the affected files.

No, I don't have anything from the list above.
The RBTX4927 is basically my last MIPS-based system I do boot
current kernels on.

In active use, not for development:
  - Ubiquiti EdgeRouter-X (Ralink-based).

Stored in my attic:
  - NetGear WNDR4300 (AtherOS-based),
  - MikroTik Routerboard 150 (ADMtek-based, no (longer?) supported upstream),
  - NEC DDB VRC-5476 (upstream support removed 15 years ago ;-)

These patches should not break RBTX4927:

  net: tc35815: Drop support for TX49XX boards
  spi: txx9: Remove driver
  mtd: Remove drivers used by TX49xx
  char: hw_random: Remove tx4939 driver
  rtc: tx4939: Remove driver
  ide: tx4938ide: Remove driver

And these patches just break audio-support only.

  dma: tx49 removal
  ASoC: txx9: Remove driver

I think dma and ASoC drivers are hard to maintain now, and can be
dropped for basic support for RBTX4927.
(TX39 boards does not have audio-support, so dma txx9 driver can be
dropped too)

Indeed.

Agreed, I don't test audio anyway, but I know it used to work (I had
intended to use the board as an MPD media server, but never got beyond
the prototyping phase).

Applied, thanks!
