(gdb) help add-symbol-file
Load symbols from FILE, assuming FILE has been dynamically loaded.
Usage: add-symbol-file FILE ADDR [-s <SECT> <SECT_ADDR> -s <SECT> <SECT_ADDR> ...]
ADDR is the starting address of the file's text.
The optional arguments are section-name section-address pairs and
should be specified if the data and bss segments are not contiguous
with the text.  SECT is a section name to be loaded at SECT_ADDR.

So ADDR is not the starting address (reboot_code_buffer) but you must also add
to it the VMA of the .text section of FILE (see `readelf -WS FILE').
