From 22ec9f9a72955d2364061db72520b85602077414 Mon Sep 17 00:00:00 2001 From: Zheng Bao Date: Mon, 18 Feb 2013 16:56:09 +0800 Subject: AMD S3: Introduce Kconfig variable 'S3_DATA_SIZE' Currently the size of the volatile storage for S3 reserved in the image is hardcoded to 32768 bytes. Make that configurable by introducing the Kconfig 'S3_DATA_SIZE'. As the storage space is needed for storing non-volatile, volatile and MTRR data, add a check if the size is big enough.
