From 6e2d0c1b90251b4b61af582d2598cdbd38591db7 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ky=C3=B6sti=20M=C3=A4lkki?= Date: Fri, 28 Jun 2019 10:08:51 +0300 Subject: arch/x86: Adjust size of postcar stack MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit With VBOOT=y && VBOOT_MEASURED_BOOT=y message digest will be allocated from the stack and 1 KiB reserve used with the recent platforms was no longer sufficient. The comment of LZMA scratchpad consuming stack was obsolete for postcar, so these can be reduced to same 4 KiB.
