Humm, definitely the wrong direction. Generally, code for specific
bindings does not go in drivers/of/. There used to be some, but we've
moved it to the appropriate subsystems. kexec was an exception to not
have 2 copies of the same code in arch/.
The function I am moving here is called by the TPM subsystem and also now by
of/kexec.c. The latter is compiled under the following conditions:
ifdef CONFIG_KEXEC_FILE
ifdef CONFIG_OF_FLATTREE
obj-y += kexec.o
endif
endif
The code that current calls it is compiled under the following conditions:
tpm-$(CONFIG_OF) += eventlog/of.o
To make it available to both I could keep it in the TPM subsystem like this:
obj-$(CONFIG_OF) = tpm_of.o
Jarrko, if you read this, any comment?
Stefan
Why can't you convert of_tpm_get_sml_parameters() to inline function?
I can do that and put it into include/linux/tpm.h. The only concern
would have been the size of the function.
Thanks,
Stefan
