I didn't mean the interpretation of which fuses mean what semantically, but rather the data format of the file. IIRC looking at the code, it's just a binary dump of the fuses, but it might be worth spelling out that it's a byte-oriented binary file, with fuse 0 in bit 0 of byte 0 etc.? -- To unsubscribe from this list: send the line "unsubscribe linux-doc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
