Hi Nico,

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.
