Please define "valid memory location". Keep in mind that:
- I can (assuming the corresponding config options are enabled)
download directly to flash memory
- there may be SRAM, NVRAN etc. on the board
- there may be frame buffer memory
- there may be "pRAM" configured
- with TFTP, the file size will not be known in advance, so it might
be difficult to validate the end address
And finally, let's remember Unix design philosophy:
"UNIX was not designed to stop you from doing stupid things, because
that would also stop you from doing clever things." - Doug Gwyn
But please feel free to submit a patch...
Best regards,
Wolfgang Denk

Until you walk a mile in another man's moccasins, you can't imagine
the smell.
