Hi,

I tried your code and it could decompress a LZMA-compressed kernel, very
nice. I had to add some WATCHDOG_RESET() calls to LzmaDec.c because my
device has a slow mpc823 CPU.
However booting does not continue and I do not know why.

After this the device reboots.

Attached you will find the config used to compile U-Boot.
I started with CONFIG_SYS_LOAD_ADDR 0x200000 and increased it to 0x500000,
but it did not help. I suppose decompressing a LZMA-compressed kernel takes
more RAM, my box has 64MB which I think should be enough. The decompression
should work with 32MB RAM as well as this is the standard amount.

I am not an expert when it comes to handling a Linux kernel at boot time so
pointing to lots of howto's is appreciated ;)

Cheers, rhabarber1848
