[U-Boot] spi: cadence_qspi_apb: cache issues on mach-socfpga

Hi,

I ran into the same issue with the cadence qspi driver and dcache as Jason reported (in febuary, I think - I started to monitor U-Boot in july only).

May I ask what's the status here? I do need fixes for this to keep mach-socfpga running with qspi. I currently set dcache off globally and it works, but I still need the trigger-address fix (which is fixed by Jason's patch to use linux DT bindings).

Regarding the bounce buffer change: isn't it wrong to use the generic bounce buffer here? Given the dcache calls in it, it seems like this one is for DMA but we're doing cpu copy in the cadence qspi driver.

Anything I can do to get this pushed?

Thanks, Simon
