From 09230cbc1baba68e0ca1e7c489344ce5d35c6f27 Mon Sep 17 00:00:00 2001 From: Christoph Hellwig Date: Tue, 24 Apr 2018 09:00:54 +0200 Subject: swiotlb: move the SWIOTLB config symbol to lib/Kconfig This way we have one central definition of it, and user can select it as needed. The new option is not user visible, which is the behavior it had in most architectures, with a few notable exceptions: - On x86_64 and mips/loongson3 it used to be user selectable, but defaulted to y. It now is unconditional, which seems like the right thing for 64-bit architectures without guaranteed availablity of IOMMUs. - on powerpc the symbol is user selectable and defaults to n, but many boards select it. This change assumes no working setup required a manual selection, but if that turned out to be wrong we'll have to add another select statement or two for the respective boards.
