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
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.
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:
15 # setenv bootcmd fatload mmc 0 $confaddr plan9.ini; ...; bootm
