[S] Change in coreboot[main]: device/Kconfig: Add an option to allocate above 4G by default
by Arthur Heymans (Code Review) 11 Jan '24

11 Jan '24

Attention is currently required from: Arthur Heymans, Chen, Gang C, Jincheng Li, Nico Huber, Paul Menzel, Shuo Liu. Hello Chen, Gang C, Jincheng Li, Lean Sheng Tan, Nico Huber, Paul Menzel, Shuo Liu, build bot (Jenkins), I'd like you to reexamine a change. Please visit https://review.coreboot.org/c/coreboot/+/78331?usp=email to look at the new patch set (#19). Change subject: device/Kconfig: Add an option to allocate above 4G by default ...................................................................... device/Kconfig: Add an option to allocate above 4G by default Historically resource allocation in coreboot was 32bit x86 thing. To remain compatible with this behavior (e.g. to keep 32bit payloads happy), resource allocation limits resources to 32 bits unless explicitly overridden. However this behavior is not always appropriate: e.g. on non x86 platforms the PCIe mem decode window could be above 4G. Another case on x86 is where the decode window(s) below 4G are not adequate for fitting all resources and the payload is 64bit capable (e.g. Linux). This adds a Kconfig flag to override the behavior to limit resources to 32bit by default and to allocate resources according to the real hardware limits.
