The files in this directory are used by iscsi programs in "usr" to access and parse the iBFT data. This code uses bison/lex to parse the data, but at some point it was decided to check in the output files from bison and flex, so that the average source-code user would not have to run those tools to compile the code. Now it is likely that most folks can get those tools, but the system of having static parsing and lexical analysis has worked for so long (and isn't broken), it would be a shame to change and break it. So the static files remain, for now. If you actually wish to rerun either of these tools, the Makefile is set up so that you have to first remove the generated files (prom_lex.c for lex, prom_parse.tab.c, and prom_parse.tab.h for bison). Note: if you wish to use these object files, they have two external requirements: they need the compatability routines in sysdeps.o, and they need the file iscsi_net_util.o. Lee Duncan Mar, 2022
