Thanks for your reply.
Do you mean that we can skip FSP's temp-ram function and use alternate function from coreboot ?
We are new to this. Can you please share some sample code which skips this FSP temp RAM function ?
Thanks & Regards,

FSP's temp-ram function is redundant with proper coreboot code. I can only advice against using an FSP function if an open-source version exists. With the open-source path you'd have much more insight in what happens.
Maybe switching to the native coreboot code already helps reducing the delay.
