When running in verstage before bootblock, the PSP (ARM co-processor) is running with limited SRAM. It needs to stash the verstage console data internally until DRAM is brought up. Once DRAM is brought up the data is stashed in a "transfer buffer" region. In the current design, we are using the same region for the transfer buffer and the preram_cbmem_console region. This has the following downsides: 1) The pre-x86 buffer needs to be large enough to hold all the verstage, bootblock and romstage console logs. 2) On AMD platforms, the PSP verstage is signed. Changing the size of preram_cbmem_console after the fact will result in a mismatch of the transfer buffer between verstage and bootblock. This CL adds a new method that allows SoC specific code to copy the CBMEM console in the transfer buffer to the active CBMEM console.
