From 31218a4259708233c17fa8b09fa9d9c06ea1f2ad Mon Sep 17 00:00:00 2001 From: Patrick Rudolph Date: Mon, 30 Nov 2020 15:50:06 +0100 Subject: drivers/intel/fsp2_0: Fix running on x86_64 Add new Kconfig symbols to mark FSP binary as x86_32. Fix the FSP headers and replace void pointers by fixed sized integers depending on the used mode to compile the FSP. This issue has been reported here: https://github.com/intel/FSP/issues/59 This is necessary to run on x86_64, as pointers have different size. Add preprocessor error to warn that x86_64 FSP isn't supported by the current code. Tested on Intel Skylake. FSP-M no longer returns the error "Invalid Parameter".
