The next patches will add support for the SPI DMA controller. This will

Currently the flow for opregion init is as below:
1. Allocate memory for opregion first (cbmem_add(opregion))
2. Check if VBT size > 6 KiB (this requires extended VBT support)
3. In case of extended VBT requirement, we allocate another chunk
of memory which is equal to size of VBT (cbmem_add(extended_vbt))
4. Pass physical address pointer to OS via RVDA
We can optimize the above flow to allocate single chunk of memory by
checking VBT size in earlier step. The new optimized flow for opregion
init is as below:
1. Check if VBT size > 6 KiB (this requires extended VBT support)
2. In case of extended VBT requirement, total memory to be allocated
is calculated as sizeof(opregion) + sizeof (extended_vbt)
In case where VBT size is < 6 KiB, total memory requirement would
be equal to sizeof(opregion)
3. Based on above calculation, allocate single chunk of memory based on
total size.
This will also be helpful for the case of virtualization where guest
users don't have access to physical address and when it needs relative
address of VBT compared to absolute address.
In case of opregion 2.1 spec, we need to pass relative address of
VBT from opregion base in RVDA. This optimization will help in meeting
this requirement since relative address of extended VBT is easy to get.
This change will ensure that it meets opregion specification
requirement and will be compatible with future versions as well.

This patch adds functionality to attempt to allow booting in a secure
configuration (albeit with potentially reduced functionality) when the
CSE EOP message fails in any way. These steps come from the CSME BWG
(13.5, 15.0, 16.), and tell the CSE to disable the MEI bus, which
disables further communication from the host. This is followed by
requesting the PMC to disable the MEI devices. If these steps are
successful, then the boot firmware can continue to boot to the
OS. Otherwise, die() is called, prefering not to boot over leaving the
insecure MEI bus available.
