QSPI mode on imx6ull evk

[Matthias Weißer]

Hi

I currently try to get the QSPI flash on the imx6ull evk working in quad mode.
This attempt fails as when spi_child_post_bind is called there seems to be no
spi child in the udevice (spi at 21e0000) which then leads to
spi_slave_ofdata_to_platdata not called and the according definitions in the
device tree (like spi-rx-bus-width) are not parsed. I am using plain v2020.07
without any modifications on the MCIMX6ULL-EVK.

mx6ull_14x14_evk_defconfig was the config I used.

I tried to CC some of the people involved in the development of the affected
parts of u-boot. Please correct me if I am wrong. Any help would be appreciated.


Regards

Matthias
