From 4fb64d0b880c698cba92f5ec2e4d39f3bdb92fc6 Mon Sep 17 00:00:00 2001 From: Martin Roth Date: Tue, 10 Jan 2017 11:15:13 -0700 Subject: fsp 1.0 systems: Check for NULL when saving HobListPtr Die if cbmem_add can't allocate memory for the hob pointer. This shouldn't ever happen, but it's a reasonable check. - fsp_broadwell_de already had a check, but it returned to someplace inside the FSP. Just die instead.
