Hi,

this is correct, the unpatched version of lib_generic/lzma/LzmaTools.c
has this code in line 137:

*uncompressedSize = outProcessed;


I added the same code to the lzma465 patch and it works for me:

--- u-boot-2009.06.org/lib_generic/lzma/LzmaTools.c     2009-07-17

     if (res != SZ_OK)  {
         return res;
     }


Attached you will find a patch which also includes the watchdog stuff I 
need along with the formentioned patch. I do not know if all 
WATCHDOG_RESET() calls are really necessary but I have a 66 MHz CPU here 
which takes 12s to decompress a 550kb LZMA-compressed kernel.

Cheers, rhabarber1848
