That said;
## is concatenate
# is stringfy
In you case it would look like this
cmd_tbl_t __u_boot_cmd_mtest Struct_Section = {"mtest", 5, 1,
do_mem_mtest, "simple RAM read/write test", "[start [end [pattern
[iterations]]]]"}
This struct is placed in its own section because u-boot internals can than
easily refer to this section to read/use the uboot commands.
