Firmware Upstreaming

This page should cover firmware upstreaming for Talos and other RaptorCS systems. Because it would be very useful to be able to build new firmware directly from upstream sources.

Host firmware

working with the 04-16-2019 branch, which is in the v2 firmware

SBE

same for Blackbird and Talos = https://git.raptorcs.com/git/talos-sbe/log/

• Send IPL status codes to BMC over LPC port 81h/82h = https://github.com/open-power/sbe/pull/15
• Disable SBE console print as it significantly slows down SBE execution

HCODE

same for Blackbird and Talos = https://git.raptorcs.com/git/talos-hcode/log/

• Update ring files from hostboot-binaries
• Allow split of HOST and TARGET toolchain binary names - useful, but likely not required
• Revert "Self Save: Added support for SPR self save in CME hcode(func ver)" - should be superceeded by a real fix in https://github.com/open-power/hcode/commit/cc0b781abd67673240c208df7c77d2d37906057f

-> no changes needed

Hostboot

same for Blackbird and Talos = https://git.raptorcs.com/git/blackbird-hostboot/log/, resp. https://git.raptorcs.com/git/talos-hostboot/log/, but they carry the same patches

• cap voltage offset when biased
• Add detailed ISTEP output option to hostboot
• Don't try to add proprietary CAPP microcode image to PNOR (could be skipped in upstream)

OCC

same for Blackbird and Talos = https://git.raptorcs.com/git/talos-occ/log/

• remove prebuilt GPU1 binary - not required for upstream
• Fix build failure on GCC8

skiboot

Tracked in patchwork: https://patchwork.ozlabs.org/patch/1210958/

op-build

• Initial port is upstream from https://github.com/open-power/op-build/pull/3341 as of https://github.com/open-power/op-build/commit/592eff791509d66525aea78ae8d35e99c8626a56

Other things to consider from Raptor's branch:

• skiroot kernel config changes
• adds openpower/scripts/talos-extra-cleanup script - could be generally useful
• adds pnv_lpc tool - possibly could be omitted for Talos if skiboot uses LPC observer same as Blackbird
