From c02dd3f312ec08635f024d4c335540ac8d4ace46 Mon Sep 17 00:00:00 2001 From: Subrata Banik Date: Fri, 15 Sep 2023 23:05:48 +0530 Subject: [PATCH] soc/intel/meteorlake: Add configs for pre-production silicon Certain Intel Meteor Lake specific features are only enabled in production silicon (not available in early SoC aka pre-production silicon). - SPI usage for production SoC is much optimized compared to pre- production silicon. - MIPI driver requires a way to identify between pre-prod vs prod silicon. This patch adds config options to select the Pre-Production aka Engineering Silicon (ES). The mainboard users can specify which underlying SoC is being used for the target platform. BUG=b:300652989 TEST=No change in the functionality, just added new configs.
