TPM: TCG_ATMEL should depend on HAS_IOPORT
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 from Atmel say Yes and it
will be accessible from within Linux. To compile this driver
