Sorry, may be I confused you. I indent to use only one core for u-boot. I wanted to ask whether we need to update the cache management to boot for ARM Cortex A9 SMP if we take ARM Cortex A8 code as base. I have tried and did not require any change on top of A8 code to run u-boot on A9 SMP. Is that right approach? -- Regards, Sudeep
