2021-11-19Documentation: Add some notes about how to integrate FSPPatrick Georgi
While we don't _want_ FSP, we can't get around it sometimes. But when using it, we can still try to establish best practices to make life easier for everybody.

2020-07-26soc/intel/common/basecode: Implement CSE update flowRizwan Qureshi
The following changes are done in this patch: 1. Get the CSE partition info containing version of CSE RW using GET_BOOT_PARTITION_INFO HECI command 2. Get the me_rw.version from the currently selected RW slot. 3. If the versions from the above 2 locations don't match start the update - If CSE's current boot partition is not RO, then * Set the CSE's next boot partition to RO using SET_BOOT_PARTITION HECI command. * Send global reset command to reset the system. - Enable HMRFPO (Host ME Region Flash Protection Override) operation mode using HMRFPO_ENABLE HECI command - Erase and Copy the CBFS CSE RW to CSE RW partition - Set the CSE's next boot partition to RW using SET_BOOT_PARTITION HECI command - Trigger global reset - The system should boot with the updated CSE RW partition. TEST=Verified basic update flows on hatch and helios.

2020-04-09soc/intel/cannonlake: Steal no memory for disabled IGDChristian Walter
Set IgdDvmt50PreAlloc to zero if InternalGfx is disabled. It's 'correct' to do it like this, otherwise the FSP would always allocate memory for the IGD even if it is disabled. In addition the FSP enables the graphics panel power even if no IGD is present which leads to a crashing FSP. Thus, if no IGD is present we switch off the panel via UPDs. Refer to this issue on IntelFSP for details: https://github.com/IntelFsp/FSP/issues/49 Tested on: * CFL platform with IGD * CFL platform without IGD Change-Id: I6f9e0f9855224614471d8ed23bf2a9786386ddca Signed-off-by: Christian Walter <christian.walter@9elements.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/39454 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Angel Pons <th3fanbus@gmail.com> Reviewed-by: Paul Menzel <paulepanter@users.sourceforge.net> Reviewed-by: Nico Huber <nico.h@gmx.de>
