Wilson - trying to test this out on a Galileo Gen2 - which branch are you doing
this against ?
I can apply the first patch you're proposing to squash your commit into
https://lkml.org/lkml/diff/2014/10/7/390/1
but then trying to apply the first in your series on top of that patch I get
deckard@aineko:~/Development/linux$ git
apply ../patches/capsule_wilson/1_2.eml
../patches/capsule_wilson/1_2.eml:72: trailing whitespace.
EXPORT_SYMBOL_GPL(efi_capsule_supported);
error: drivers/firmware/efi/capsule.c: No such file or directory
https://kernel.googlesource.com/pub/scm/linux/kernel/git/mfleming/efi/+/
capsule/drivers/firmware/efi/capsule.c
??
If you are applying Matt's patch https://lkml.org/lkml/diff/2014/10/7/390/1 which
had been created 1 year ago to mainline vanilla kernel (Linux 4.3-rc4), you are not
able to direct patch in due to the Makefile error below:
~/MyWorks/linux_mainline$ git apply .git/rebase-apply/0001 --reject

You should resolve the Makefile error and then git add 5 files below:
- arch/x86/kernel/reboot.c
- drivers/firmware/efi/Makefile
- drivers/firmware/efi/reboot.c
- include/linux/efi.h
- drivers/firmware/efi/capsule.c
then you are able to patch in my patchset.
If so - then why not use the interface here ?

capsule
(Sorry I know I'm coming to this thread late)
Aside from that, I'm curious which types of capsules you've used here too -
does it include the MFH header ? Keep in mind the initial firmware that
shipped with Galileo will depend on that MFH being present.
http://download.intel.com/support/processors/quark/sb/quark_secureboot
prm_330234_001.pdf
- Section A1 - table 7 ?
So if we boot a 4.x kernel with that initial firmware version 0.75 if memory
serves - it's important that the capsule.c code handles the MFH.
Already got agreement with Matt that Quark Security Header patch will not
be upstream to mainline as it is not a standard header. So Intel will carry this
patch ourselves.
Right... so what sort of capsule are you testing with ?
