1 Plan 9 from Bell Labs kernel images require additional setup to pass 2 configuration information to the kernel. An environment variable named 3 confaddr must be defined with the same value as CONFADDR (see mem.h). 4 Use of this facility is optional, but should be preferable to manual 5 configuration. 6 7 When booting an image, arguments supplied to the bootm command will be 8 copied to CONFADDR. If no arguments are specified, the contents of the 9 bootargs environment variable will be copied. 10 11 If no command line arguments or bootargs are defined, CONFADDR is left 12 uninitialized to permit manual configuration. For example, PC-style 13 configuration could be simulated by issuing a fatload in bootcmd: 14 15 # setenv bootcmd fatload mmc 0 $confaddr plan9.ini; ...; bootm 16 17 Steven Stallion 18 June 2013 19
