commit d8718c50eb1b1222b53a344912d6202d0cba2f5d Author: Zheng Bao fishbaozi@gmail.com Date: Mon Feb 18 16:56:09 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, add a check if the size is big enough.
