Subject: sunxi: move #ifdef guards around tzpc_init() to header file
X-Git-Url: http://git.dujemihanovic.xyz/%22http:/www.sics.se/static/%7B%7B%20%24image.RelPermalink%20%7D%7D?a=commitdiff_plain;h=02780a1c2675916bea8dbfb594bba7936ff538d5;p=u-boot.git

sunxi: move #ifdef guards around tzpc_init() to header file

Some later 32-bit SoCs require some setup of the Secure Peripherals
Controller, which is handled in tzpc_init().
At the moment this is guarded in board.c by some #ifdefs selecting the
SoCs that need it.

Move those #ifdef guards into the header file, providing an empty stub
function for all other SoCs, so that the #ifdefs can be removed from the
.c file, to improve readability.
