Plan 9
|
|
======
|
|
|
|
Plan 9 from Bell Labs kernel images require additional setup to pass
|
|
configuration information to the kernel. An environment variable named
|
|
confaddr must be defined with the same value as CONFADDR (see mem.h).
|
|
Use of this facility is optional, but should be preferable to manual
|
|
configuration.
|
|
|
|
When booting an image, arguments supplied to the bootm command will be
|
|
copied to CONFADDR. If no arguments are specified, the contents of the
|
|
bootargs environment variable will be copied.
|
|
|
|
If no command line arguments or bootargs are defined, CONFADDR is left
|
|
uninitialized to permit manual configuration. For example, PC-style
|
|
configuration could be simulated by issuing a fatload in bootcmd::
|
|
|
|
# setenv bootcmd fatload mmc 0 $confaddr plan9.ini; ...; bootm
