Hi, fenghua: I found you defined these marcoes in vexpress_aemv8a.h : #define CONFIG_SYS_DCACHE_OFF #define CONFIG_SYS_ICACHE_OFF
Most ARMv7 platform will enable Icache to make code run faster. So, why not turn on Icache on ARMv8 FVP model? Is there any side-effects?
I can only guess why David choose to do so. The function model doesn't have cache implemented. I am in the development of ARMv8 platform on an emulator which is much closer to a real chip. I have found several cache related issue with current code. If you want to check, please see http://patchwork.ozlabs.org/bundle/yorksun/armv8_fsl-lsch3/
