If this is your concern, then a compile-time setting makes little sense - you don't really expect that a user in this situation will build another U-Boot image after selecting other build options, install it (with the risk of bricking his device (keep in mind that not everybody has access to a JTAG debugger), and continue this so long until he finds a configuration that works for his combination of U-Boot and Linux settings. > I submitted this patch to support both ordering that the correction routine > contains (123 and 213). But it makes no sense as a compile time option. If you want to help users, then this must be implemented in a way that is selectable at run-time, for example by simple setting an Best regards, Wolfgang Denk -- DENX Software Engineering GmbH, MD: Wolfgang Denk & Detlev Zundel HRB 165235 Munich, Office: Kirchenstr.5, D-82194 Groebenzell, Germany Phone: (+49)-8142-66989-10 Fax: (+49)-8142-66989-80 Email: w...@denx.de "Everybody is talking about the weather but nobody does anything about it." - Mark Twain _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
