Hi,

I am porting tpm emulator to versatilepb, which is an arm platform. I
have some problem with CFLAGS from /arch/arm/Makefile when building
the kernel module for this software. I cannot figure out what to do in
this case. Following is the error:

[root@develbox tpm_emulator-0.5]# make
Making all in tpmd
make[1]: Entering directory `/embedded/tpm_emulator-0.5/tpmd'
make[1]: Nothing to be done for `all'.
make[1]: Leaving directory `/embedded/tpm_emulator-0.5/tpmd'
Making all in tpmd_dev

make[1]: *** [all] Error 2
make[1]: Leaving directory `/embedded/tpm_emulator-0.5/tpmd_dev'
make: *** [all-recursive] Error 255

kindly help me understand the core issue here and point out some solutions.
