NAK. We went over this before. The bug is in your SPI master controller driver, and the fix there involves mapping large reads into multiple smaller reads. (Example, 128K read as two 64K reads instead of one of 128K. It's *NEVER* appropriate to commit to patching all upper level drivers in order to work around bugs in lower level ones. The set of such upper level drivers that may need bugfixing is quite large, most will never be used with your buggy controller driver, and all such patches will need testing (but the test resources are probably not available). Whatever SPI controller driver you're working with is clearly buggy ... but not unfixably so. DO NOT head down the path of requiring every SPI device driver to include workarounds for this odd little SPI master driver bug. - Dave _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
