Since I was around back in the Intel Tiano days and I've worked on all the PI
specs I can share the history.
The reset vector is a hardware thing. It is usually at the top or bottom of the

In platforms built for boot media other than SPI flash there has been a
compelling
need for silicon and platform code to be aware of the firmware boot media but
apart from the UEFI variable driver (which is a special case being addressed

I am not sure if there is a silicon scope around the FirmwareBootMediaLib. Have
we considered adding this interface to MdePkg, instead?

First of all, let me say that I think before upstreaming to master,
you ought to look into merging PlatformBootManagerLibs for all Risc-V

There is a generic issue here, and not just with this patch:
It is being added *after* the U500 platform, which depends on this.

Hi Mike and Liming,
How do you think about to use IoLibArm as the I/O lib instance for RISC-V arch?
I personally don't like to use IoLibArm.c in [Source.RISCV64] section, instead
I would like to use IoLibRiscV.c which conform with current source file

Jason,
The only time the HardwareInstance is optional (and set to 0) is if the system
can guarantee that there is at most one instance of the device in the system.
This can only be guaranteed for an integrated device. Any devices that an end
