On m68k, I get: drivers/char/tpm/tpm_atmel.h: In function ‘atmel_get_base_addr’: drivers/char/tpm/tpm_atmel.h:129: error: implicit declaration of function ‘ioport_map’ drivers/char/tpm/tpm_atmel.h:129: warning: return makes pointer from integer without a cast The code in tpm_atmel.h supports PPC64 (using the device tree and ioremap()) and "anything else" (using ioport_map()). However, ioportmap() is only available on platforms that set HAS_IOPORT. Although PC64 seems to have HAS_IOPORT, a "depends on HAS_IOPORT" should work, but I think it's better to expose the special PPC64 handling explicit using "depends on PPC64 || HAS_IOPORT".

If you have a TPM security chip in your system, which
|
|
implements the Trusted Computing Group's specification,
|
|
say Yes and it will be accessible from within Linux. For
|
|
more information see <http://www.trustedcomputinggroup.org>.
|
|
An implementation of the Trusted Software Stack (TSS), the
|
|
userspace enablement piece of the specification, can be
|
|
obtained at: <http://sourceforge.net/projects/trousers>. To
|
|
compile this driver as a module, choose M here; the module
|
|
will be called tpm. If unsure, say N.
|
|
Notes:
|
|
1) For more TPM drivers enable CONFIG_PNP, CONFIG_ACPI
|
|
and CONFIG_PNPACPI.
|
|
2) Without ACPI enabled, the BIOS event log won't be accessible,
|
|
which is required to validate the PCR 0-7 values.
