commit 03d26c6d02caefad6b12ff5d04c9c4c4f782976e Author: Zheng Bao fishbaozi@gmail.com Date: Sun Feb 17 17:11:27 2013 +0800
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. Therefore add a check if the size is big enough.
