[PATCH 1/4] scripts: Makefile.pic: define __NO_FORTIFY without value

[Ahmad Fatoum]

The default for -D without = is to define the symbol to expand to 1.
This is nt what we want, because pbl/string.c defines it without value
leading to a build error. Fix this by defining it empty explicitly
instead.

[PATCH 2/4] ARM64: configs: multi_v8: disable layerscape temporarily

[Ahmad Fatoum]

With multi_v8, we build everything in a single build and that makes the
layerscape PBLs exceed their hard limit of 64K failing the build.

Until resolved, let's disable it from the defconfig. Users can still use
the dedicated layerscape defconfigs.

This doesn't happen here. The biggest PBL I get here is the ls1046ardb
one with 58304 bytes. Are you using some other compiler than me?

The Layerscape PBLs for the other boards are much smaller because they
don't use a fixed SDRAM controller setup rather than detecting DIMMs via
SPD. Would it be enough to disable the LS1046ardb board?

I can't reproduce it now, but seem to recall I didn't change anything
intentionally..

We already have a layerscape defconfig for people intent on using the
RDB. Most other people don't care about this board for
multi_v8_defconfig, so it's unfortunate that you can't enable things
without risking build breakage.

I have patches that I need to finish in the coming months that make too
big images a soft error like we do for missing firmware. I would prefer
we add back Layerscape support after these patches are merged.

Thanks,
Ahmad

[PATCH 3/4] ARM: configs: multi: configure CONFIG_CONSOLE_ACTIVATE_ALL_FALLBACK

[Ahmad Fatoum]

To be more robust against regressions and to allow use for EFI payload,
where nothing yet enables a default console, have barebox activate all
consoles if none have been registered normally.

[PATCH 4/4] ARM64: configs: add multi_v8_efi_defconfig

[Ahmad Fatoum]

We will want to have a efi_defconfig once all necessary components are
in place, but for now let's just add a config that extends
multi_v8_defconfig with an EFI stub.

To use, get QEMU_EFI.fd (e.g., from Debian qemu-efi-aarch64) and run:

  qemu-system-aarch64 -kernel images/barebox-dt-2nd.img \
  -bios QEMU_EFI.fd -machine virt,highmem=off -cpu cortex-a57 \
  -m 1024M -nographic -serial mon:stdio -trace file=/dev/null

A labgrid YAML will follow once we can provide QEMU_EFI.fd there.
