Hi Sascha,
Thanks for testing master-test branch.

Please find the test branch for this patch series, here.

Request to test these changes on your boards.
Let me know for any issues.
Thanks for setting up a branch for easier testing. I've rebased the
CuBox support patch series [1] on top of your branch and tested the
result. SPI flash support worked before on CuBox, but fails with your
branch.
At build time, the following warnings are issued (found using
DBGFLAGS="-g -Werror"):

Yes, i will fix this, please use -Wunused-variable as of now for testing
to make build successful.
At run time, automatically reading the environment from SPI flash
fails. "sf probe" and "sf read" both appear to work, but "sf probe"
reports 64KiB page size and "sf read" only yields 0xff rather than the
U-Boot binary that's at the start of SPI flash:

Why this is got failed while env reading and again succeeded in below

Do you have any changes on ur controller driver w.r.t to working
scenario in below log on master.?
I will work directly, as no changes of spi_flash_ops.
Can you try to write some thing and read it back.

For comparison, this is what it looks like on top of current master:

Is there something that needs to be done differently now? Some
additional function to call in board setup code or defines to set in the
board configuration?
