From c632bda2f6fe9dad5da4118ea9bb762a8eff1583 Mon Sep 17 00:00:00 2001 From: Tim Wawrzynczak Date: Fri, 20 Mar 2020 10:58:51 -0600 Subject: soc/intel/tigerlake: Update DCACHE_BSP_STACK_SIZE According to the latest Tigerlake Platform FSP Integration Guide, the minimum amount of stack needed for FSP-M is 256KiB. Change DCACHE_BSP_STACK_SIZE to reflect that (plus 1KB previously determined empirically). JSL requires 192KiB.
