-The code is intended to decompress kernel, being compressed using lzma utility
-build using 7zip LZMA SDK. This utility is located in the LZMA_Alone directory
-
-decompressor code expects that your .trx file consist of three partitions: 
-
-1) decompressor itself (this is gziped code which pmon/cfe will extract and run
-on boot-up instead of real kernel)
-2) LZMA compressed kernel (both streamed and regular modes are supported now)
-3) Root filesystem
-
-Please be sure to apply the following patch for use this new trx layout (it will
-allow using both new and old trx files for root filesystem lookup code)
