Applied to u-boot-nand-flash -- I missed it earlier. Next time please make sure "nand" is in the subject line. Ideally prefix it as "nand/fsl_ifc: wait tWB time..." rather than "driver/mtd/IFC:Wait tWB time...". -Scott _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
