Glad to see that happen sooner than I had expected. Looks like the patch series is in a good shape already, and I'm happy to see the u-boot spi-nor layer being based on the Linux one. Good job, and thanks again for working on that! Boris _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de https://lists.denx.de/listinfo/u-boot
