+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)
