DT: error in generated_dts_board_fixups.h for board: frdm_k64f

[jakub-uC]

It is not possible to build application:
~/zephyr/zephyr/tests/net/all
for frdm_k64f board.

1. Go to ~/zephyr/zephyr/tests/net/all
2. mkdir b && cd b
3. cmake -GNinja -DBOARD=frdm_k64f ..
4. ninja
5. See error

Expected behavior
Project will compile

Impact
It is not possible to build this test for frdm_k64f board. In my opinion it is serious.

Environment (please complete the following information):

• OS: Linux
• Zephyr SDK
• Commit SHA or Version used: acaae57 (the newest master)

Screenshots or console output

Additional context
I can build it without any error for nrf52840_pca10056 board.

The issue is that the build isn't valid on frdm-k64f as defined by default. It enables bluetooth, but there is no bluetooth controller. BT_UART is enabled and expects that zephyr,bt-uart is defined in the dts, but since the based frdm-k64f doesn't have bt, that isn't set. Thus the build errors.

[MaureenHelm]

Is this purely a build test or is it supposed to do something at runtime? If it's just a build test, then you can build it like this:

$ cmake -DBOARD=frdm_k64f -DSHIELD=frdm_kw41z ..
$ make

It won't work at runtime because there is a pin conflict between Ethernet and BT UART.

[agansari]

This issue will arise on any board without Bluetooth on board/soc that requires an external shield, not just K64F.
To fix this we can add something like the following:

diff --git a/tests/net/all/CMakeLists.txt b/tests/net/all/CMakeLists.txt
index 4491e40bd9..6a5aaddde3 100644
--- a/tests/net/all/CMakeLists.txt

+    set(SHIELD frdm_kw41z)
+endif()

 project(all)

But as @MaureenHelm asked, is this a build test?
If yes, then the change above will fix it.
If no, then you need a particular HW setup described here: https://docs.zephyrproject.org/latest/boards/shields/frdm_kw41z/doc/index.html

I expect boards without BT but have arduino-i2c dts nodes to request x_nucleo* shields.

This is a build test only, the testcase.yaml says it:

  platform_whitelist: qemu_x86```
