[DistroKit] [PATCH 0/1] Add TQ-STKa93xx board

[Fabian Pflug]

The Barebox-patch has been send upstream and is already applied.

There is still a small issues to fix over:
```
barebox@TQ-Systems i.MX93 TQMa93xxLA/TQMa93xxCA on MBa93xxCA starter kit:/ detect -a
usb1: Bus 001 Device 001: ID 0000:0000 EHCI Host Controller
usb1-0: Bus 001 Device 002: ID 0424:2517 
ERROR: usb1-0-1: unable to get device descriptor (error=-110)
ERROR: usb1-0-1: USB device not accepting new address (error=80000000)
eth1: 1000Mbps full duplex link detected
```

Which seems to be related to the WLAN-Module, that is fix on the board.
Maybe a power issue. I have requested the datasheet and waiting for it
to fix it. Will probably result in an additional Barebox patch, that is
for a later time.

Board itself boots and can be used.

+From: Fabian Pflug <f.pflug@pengutronix.de>
+Date: Thu, 17 Apr 2025 10:35:16 +0200
+Subject: [PATCH] ARM: dts: tqma93xx add dummy supply to regulator
+
+The regulator for the usdhc2 references the BUCK4 as its input.
+The BUCK4 is part of the pca9451, which in turn is not a regulator
+in barebox, so there is a problem during initialisation:
+
+WARNING: imx-esdhc 42860000.mmc@42860000.of: Failed to get 'vmmc' regulator (ignored)
+
+Since the dependency could not be resolved, the reg_usdhc2_vmmc
+regulator is not correctly initialized, leaving the gpio in a floating
+state, which results in the GPIO being low, which in turn disables
+the SD-Card.

When the bootsource patch land in a barebox release, we'll be able
to drop this init script, but for now this is ok.

I think we should leave this disabled, until we start actually doing
verified boot in DistroKit.

> +CONFIG_USB_EHCI=y

Interesting. I thought the i.MX93 would use a USB 3.0 capable controller
like the i.MX8MP, but apparently it's not so.

Why not make it a proper GPT partition? I know we are not consistent
with that in existing boards, but for new board support, we should put
everything into a GPT partition from the get-go.

> +	}

Please add a barebox-environment partition as well with a comment that
it's currently unused as the environment comes from the SPI flash.

That way, we'll be able to just switch over to using environment on the
boot medium in future without changing the partition layout again.

If everything has a size and is described in the partition table, do
we still need the offset (except of course for the barebox partition).

from? missing rest of line?

Maybe even add the full command:

  imx-usb-loader platform-v8a/images/barebox-tqma93xx.img

Drop the colon, so it's an executable command.

FYI, you can also use the barebox /mnt/nfs automount:

  dude06$ ln -s /ptx/work/user/fpg/DistroKit/platform-v8a/root \
		~fpg/nfsroot/${global.hostname-from-barebox}
  barebox$ nv net.server=dude05
  barebox$ nv user=fpg
  barebox$ boot /mnt/nfs

CONFIG_IMX93 sets CONFIG_AHAB, which in turn sets CONFIG_HAB
Not really possible to disable.

Nope, USB2.0 only

I have no opinion about it. It was just copy & paste from all the other
boards. Will do what the majority agrees upon.

You're welcome :)

Ah, ok. Fine by me then.

If the majority is what's already being done, then no progress is
possible ;)

Please try describing all partitions in the GPT. If there are unforeseen
problems, we can revert back to the old scheme with a comment explaining
it. :)
