From 7736bfc443a913a9cde46406bcfc38015ec71f47 Mon Sep 17 00:00:00 2001 From: Michael Niewöhner Date: Tue, 22 Oct 2019 23:05:06 +0200 Subject: soc/intel/sgx: convert SGX and PRMRR devicetree options to Kconfig MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The devicetree is not made for user-choosable options, thus introduce Kconfig options for both SGX and the corresponding PRMRR size. The PRMRR size Kconfig has been implemented as a maximum value. At runtime the final PRMRR size gets selected by checking the supported values in MSR_PRMRR_VALID_CONFIG and trying to select the value nearest to the chosen one. When "Maximum" is chosen, the highest possibly value from the MSR gets used. When a too strict limit is set, coreboot will die, printing an error message.
