Whiteboard

[ibiris - 24Oct2011]: this blueprint is now obsolete, there is a new direction and decisions taken during the boot-architecture weekly meetings. The new work will be handled via new blueprints after Linaro Connect @ Orlando (Oct31-Nov04 2011)

UEFI on ARM

Agenda
 * Introduction
 * Requirements and Rational
 * Current state
  * Who is working on what
 * Goals for 11.11
  * Do we support a UEFI target in 11.11?
  * If so, which one?
  * If so, what are the work items?

Requirements and Rational
 * Secure Boot
 * PXE
 * Secure Boot
 * licensing - adversion to GPL'd firmware (U-Boot)
 * UEFI Required by Microsoft for Windows on ARM
 * Enterprise management
  * Want to use same tools/techniques to manage x86 and ARM servers

Concerns
 * Do not want another boot interface
  * Majority of ARM systems do/will not use UEFI;-
  * Must be able to boot OS regardless of firmware implementation
 * How big is UEFI?
  * It's a whole operating system - unlike anything else
 * No firmware-resident device drivers please

Who is working with UEFI:
 * ARM
 * Hewlett Packard
 * Other vendors have not gone public
