I would like remove Linux stuff atleast on this file becuase it's difficult for me to read or review the code and also driver/spi have fully u-boot dm stuff. I know it's easy for Linux sync but for this we can do manual sync what ever need. I'm on something what from Linux. _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de https://lists.denx.de/listinfo/u-boot
