From: Jens Taprogge Date: Thu, 27 Sep 2012 10:37:28 +0000 (+0200) Subject: Staging: ipack/bridges/tpci200: change tpci200_slot->*_phys type. X-Git-Tag: firefly_0821_release~3680^2~1519^2~1212 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=bb29ab86d18da68e5c7f05814c07d5eb8bdb4652;p=firefly-linux-kernel-4.4.55.git Staging: ipack/bridges/tpci200: change tpci200_slot->*_phys type. Previously the *_phys fields were of type ipack_addr_space, which use void pointers to refer to memory addresses. Since the *_phys fields refer to unmapped memory, this is not correct. Introduce a new struct ipack_region (which uses phys_addr_t to refer to the start of a region) and use that as a replacement for struct ipack_addr_space. struct ipack_region is defined in ipack.h because it is planned to later expose the physical addressed to the IPack Module drivers.
