From 191bd827344302561c2aa900e5e5ecdd088c5888 Mon Sep 17 00:00:00 2001 From: Subrata Banik Date: Sat, 21 Nov 2020 19:30:57 +0530 Subject: [PATCH] soc/intel/alderlake: Update DCACHE_BSP_STACK_SIZE and DCACHE_RAM_SIZE According to the latest Alderlake Platform FSP Integration Guide, the minimum amount of stack needed for FSP-M is 512KiB. Change DCACHE_RAM_SIZE and DCACHE_BSP_STACK_SIZE to reflect that (plus 1KB previously determined empirically). TEST=Able to pass FSP-M MRC training on LPDDR5 SKU without any hang.
