Unlike Linux kernel, U-Boot depends on "spi-flash" compatible to probe m25p80 spi-nor devices. Hence, add "spi-flash" compatible string to m25p80 node. Without this patch, flash device DT data is not parsed and QSPI operates in unsupported mode leading to data corruption.

Applied to u-boot-spi/master
... I don't like that we need a non u-boot prefixed string here for the binding to work as that will lead to harder re-syncs later on the dt files. Why aren't we matching on the existing part? Thanks!
I don't see this patch in u-boot master yet. If this patch was dropped due to Tom's comment above, then could you suggest how to address the issue?
Some how missed this, but do you still unable to probe the flash w/o "spi-flash"? I think there is a device_probe when !device_active(dev) that will detect the flash chip. Please try once.
thanks!
