Re: [U-Boot] Uboot and ARM SMP support

[Sudeep K N]

 I have seen the latest Uboot code there is no support for Cortex A9.
 What I would like to know is that can we reuse ARM Cortex A8 code
 for ARM Cortex A9 SMP system as bootloader must run in single core.
 Yes you can re-use the A8 code but you will need to update the cache
 management to boot you soc in smp mode
Do we need this if the bootmonitor/prebootloader is putting second
core to WFE state?

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?
