msm7x27A: Enable 7x27A specific memset routineM8960AAAAANLYA100530M8960AAAAANLYA100510M8960AAAAANLYA1005M76XXUSNEKNLYA1095M76XXUSNEKNLYA1090M76XXUSNEKNLYA1081M76XXUSNEKNLYA1080M76XXUSNEKNLYA1070
Exisiting memset routine gives sub-optimal performance for 7x27A.
Experimentally, scorpion memset routine has been found to give
better performance on 7x27A. Hence, the scorpion memset routine
is enabled for MSM7x27A using CORTEX_CACHE_LINE_32, which is enabled
by defining TARGET_CORTEX_CACHE_LINE_32 in BoardConfig.mk.
