IMO, above construct is correct. Originally, we proposed array of strings but later we changed to character array with terminating NULL entry for each element to incorporate your below review comment given in v3. "My opinion is to use a terminating NULL entry and iterate over the array until you reach it." >Best regards, >Marek Vasut _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
