Hi Tom,

You are right, EFI is preferred. FreeBSD's loader has two
implementations on arm: one that is an EFI application, and one based
on this u-boot API (known as "ubldr"). ubldr precedes the EFI
implementation by a few years.

For RISC-V my intention is also to implement both versions, and ubldr
was simpler on FreeBSD's side, so I chose to do that first. Do you
think this series is still worth pursuing if u-boot is going the way
of EFI?
