Our Ubuntu (12.04/12.10) build environment defaults configuring with
CFLAGS containing -O2. Trunk currently does not build successfully with
this on either my ARM platform or my x86_64 desktop.
This isn't causing any serious problems, but I thought I would report

Hi,
This is the evolution of the patches I submitted as an RFC at the end
of last year. Since then, I have been seconded into the Linaro
organisation - which required another contribution agreement to be
signed... Since the paperwork dragged out a bit, I actually got the
port to ARMv7 UEFI

No, BLX immediate has been supported since ARMv5T.

The current fdt support fails to update the size of the dt_struct after
adding a new node. Attached is the suggested fix.

Hi,
There is a typo in fdt.c, invoking memcpy() rather than grub_memcpy().

Subject: [PATCH 1/2] fdt: additions required for arm64 Linux loader
- Add grub_fdt_create_empty_tree() function.
- Add 64-bit setprop
This loader supports booting using the UEFI stub method only.
Currently debugging an issue with using the load_image method,
so usurping the current GRUB image context instead.

I would write the offset as sizeof (et-header) + sizeof (et-empty_rsvmap)
True. Will change.

grub_cpu_to_be32_compile_time is better suited.
