[U-Boot] arm: imx: Kernel not booting when environment is in QSPI

Matthias Weißer

Hi

I work with an imx6sx sdb. I observed that placing u-boot in QSPI
flash and also having the environment in QSPI the linux kernel doesn't
boot. The backtrace from the kernel contains 'fsl_qspi_probe'. If only
u-boot resides in QSPI and the environment is on mmc then the kernel
boots successfully.

Some more investigation showed that even when u-boot and the
environment is on mmc a simple
=> sf probe 1:0
causing the kernel not to boot.

So I suspect a problem with u-boot not leaving the QSPI hardware in a
sane state for the kernel driver to take over control. If no serial
flash operations are executed in u-boot I can access the flash in
linux via mtd.

Kernel and u-boot are both current git HEAD with minor changes. Anyone
with an idea?

Regards
Matthias
