From b082670234819108a15da6239e481f5c9d8b30ec Mon Sep 17 00:00:00 2001 From: Rizwan Qureshi Date: Thu, 16 Nov 2017 13:32:29 +0530 Subject: Kconfig: Add config for creating a second bootblock Intel PCH/Southbridges have feature that it is possible to have the southbridge/PCH look for the bootblock at a 64K or 128K/256K/512K/1MB (in case of newer SoCs) offset instead of the usual top of flash. Add configs to create a second bootblock and configure its size.
