From 997d354fcc1a32ed75fb3c2ebc523f14ec963407 Mon Sep 17 00:00:00 2001 From: Gowtham Suresh Kumar Date: Tue, 14 Dec 2021 11:09:24 +0000 Subject: [PATCH] arm-bsp/secure-partitions: corstone1000: Increase SMM Gateway variable handling capacity The maximum number of UEFI variables that can be supported by SMM gateway is currently 40. When more than 40 variables are written, or read SMM gateway returns error code. Currently this value is increased to 100 to support more UEFI variables.
