PAYLOAD_INFO is a very old feature that can add a key/value information section to a payload file. It seems to have only ever been generated by coreinfo and never really read by anything. Since CB:1721 in 2012, the feature has been inadvertently broken in practice since the `.note.pinfo` sections that contain the information get discarded from the payload before cbfstool gets to see them. Since CB:28647 in 2018, support for the section in the SELF loader was (inadvertently?) dropped, so if someone actually fed cbfstool a payload ELF that did have a `.note.pinfo` section, modern coreboot would refuse to boot the payload entirely (which is probably not a good state to leave things in). This patch removes the code to generate PAYLOAD_INFO entries entirely, but leaves the support to parse and extract those sections from old payloads in place in cbfstool.

This is a silly little program that demonstrates how cool libpayload is and also serves a purpose. It is fun and educational! Requirements ------------ You should use the coreboot reference cross compiler. If you insist on using your system compiler, some Linux distributions might require you to install a package called gcc-multilib if you are on a 64bit system. Build ----- You need libpayload to build coreinfo. So, first, you need follow the README of libpayload to build it but install libpayload into its own directory by doing this: $ make DESTDIR=/path/to/libpayload/install install Then you can build coreinfo now: $ cd coreinfo $ make menuconfig $ make
