Comments

• Schedule a separate meeting with Mark to go over the platform spec schedule
• How will custom extensions be handled. Custom extensions are beyond the scope of the platform spec. Platform defines the minimum set of functionality to claim compliance with the spec
• UART - modify Dword to 32-bit access as Dword is 64-bit. Also mention that the register contents are byte-wide.
• Linux-2022 base will mandate UEFI+EBBR compliance. U-boot with EBBR is an implementation that is UEFI+EBBR compliant.
