From 0df891697d24cf2d9d42253d0a91a9d553b2ede3 Mon Sep 17 00:00:00 2001 From: Joel Stanley Date: Wed, 28 Feb 2018 16:13:16 +1030 Subject: README: document output files A grumpy BMC developer was wondering which file to flash to the machines they were testing on. They longed for the old days where the answer was 'skiboot.lid'. Alas, those days are long past. This updates the readme with a list of the current output formats and where you might want to use them.
