Jarkko,

can you please squash this patch into the one it fixes. Unfortunately 
when rebasing you will have to fix the subsequent patch from this merge 
error

ifeq ($(openssl_available),yes)
<<<<<<< HEAD
X509TEXT=$(shell openssl x509 -in $(CONFIG_MODULE_SIG_KEY) -text 
2>/dev/null)
=======
X509TEXT=$(shell openssl x509 -in $(CONFIG_MODULE_SIG_KEY) -text)
endif
 >>>>>>> 87e968848116 (certs: Add support for using elliptic curve keys 
for signing modules)

to this:


ifeq ($(openssl_available),yes)
X509TEXT=$(shell openssl x509 -in $(CONFIG_MODULE_SIG_KEY) -text 
2>/dev/null)
endif

Thanks.

    Stefan
