Grant, Would it be beneficial to provide a way to have environment- or command-line-provided DTC arguments/flags such that the oft-required '-S <size>' and '-R <reserved>' flags can be specified? Or, are there reasonable size and reserved defaults appropriate for all platforms that can be specified? FWIW, generating a blob for Haleakala/Kilauea on the PPC405EX[r] using the above command in the patch results in complaints about lack of space for the "CHOSEN" node in u-boot. Regards, Grant
