Wed Mar 20 18:07:44 EDT 2013 geoff Do you really need u-boot-format images? What's wrong with ELF? There are other changes to the loaders in progress. This will have to wait until those are published in any case. Wed Mar 20 19:27:22 PDT 2013 stallion uImages are the preferred header when using U-Boot (even Linux has added support for uImages). The format is simpler than ELF and has some nice relocation properties that does away with the usual jump-around-the-header dance at boot. I have submitted a patch upstream to the U-Boot folks to treat Plan 9 as a first-class citizen: http://patchwork.ozlabs.org/patch/229459/ I don't mind waiting; I've already sent a message to Charles mentioning the work. Hopefully others find this useful. Tue Apr 2 23:10:12 PDT 2013 stallion Merged with latest ELF changes. Thu Jul 4 22:34:14 PDT 2013 stallion Genericized support for u-boot images in libmach.
