lx-fdtdump dumps the flattened device tree passed to the kernel from the
bootloader to the filename specified as the command argument. If no
argument is provided it defaults to fdtdump.dtb. This then allows
further post processing on the machine running GDB. The fdt header is
also also printed in the GDB console. For example:
(gdb) lx-fdtdump
fdt_magic: 0xD00DFEED
fdt_totalsize: 0xC108
off_dt_struct: 0x38
off_dt_strings: 0x3804
off_mem_rsvmap: 0x28
version: 17
last_comp_version: 16
Dumped fdt to fdtdump.dtb
>fdtdump fdtdump.dtb | less
This command is useful as the bootloader can often re-write parts of the
device tree, and this can sometimes cause the kernel to not boot.

lx-version Report the Linux Version of the current kernel.
Add a command to identify the version specified by the banner in the
debugged kernel.
This lets the user identify the kernel of the running kernel, and will
let later scripts compare the banner of the attached kernel against the
banner in the vmlinux symbols files to verify that the files are
correct.
