Subjectfsl_espi errors on v5.7.15
Date
Hi,

I'm seeing a problem with accessing spi-nor after upgrading a T2081
based system to linux v5.7.15

For this board u-boot and the u-boot environment live on spi-nor.

When I use fw_setenv from userspace I get the following kernel logs

# fw_setenv foo=1
fsl_espi ffe110000.spi: Transfer done but SPIE_DON isn't set!
fsl_espi ffe110000.spi: Transfer done but SPIE_DON isn't set!

fsl_espi ffe110000.spi: SPIE_RXCNT = 1, SPIE_TXCNT = 32
fsl_espi ffe110000.spi: Transfer done but rx/tx fifo's aren't empty!
fsl_espi ffe110000.spi: SPIE_RXCNT = 1, SPIE_TXCNT = 32

fsl_espi ffe110000.spi: SPIE_RXCNT = 1, SPIE_TXCNT = 32
...

If I run fw_printenv (before getting it into a bad state) it is able to
display the content of the boards u-boot environment.

If been unsuccessful in producing a setup for bisecting the issue. I do
know the issue doesn't occur on the old 4.4.x based kernel but that's
probably not much help.

Any pointers on what the issue (and/or solution) might be.

Thanks,
Chris
