->Description</H2
-><P
->The <B
-CLASS="COMMAND"
->exec</B
-> command is used to execute a non-eCos application, typically a
-Linux kernel. Additional information may be passed to the kernel at startup
-time. This command is quite special (and unique from the <B
-CLASS="COMMAND"
->go</B
-> command) in
-that the program being executed may expect certain environmental setups, for
-example that the MMU is turned off, etc. </P
-><P
->The Linux kernel expects to have been loaded to a particular memory
-location which is architecture dependent(0xC0008000 in the case of the SA1110).
-Since this memory is used
-by RedBoot internally, it is not possible to load the kernel to that location
-directly. Thus the requirement for the "-b" option which tells the command
-where the kernel has been loaded. When the <B
-CLASS="COMMAND"
->exec</B
-> command runs, the image will
-be relocated to the appropriate location before being started. The "-r" and
-"-s" options are used to pass information to the kernel about where a statically
-loaded ramdisk (initrd) is located.</P
-><P
->The "-c" option can be used to pass textual "command line" information
-to the kernel. If the command line data contains any punctuation (spaces,
-etc), then it must be quoted using the double-quote character '"'. If the
-quote character is required, it should be written as '\"'.
