From b4cf27f7735f9e5d80f3e79fcf355ced15461219 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Thu, 11 Apr 2013 23:13:27 +0200 Subject: ARM: exynos: introduce EXYNOS_ATAGS symbol As a preparation for multiplatform support, this introduces a new Kconfig symbol to split the ATAGS based EXYNOS platforms from the DT based ones. Turning off CONFIG_EXYNOS_ATAGS disables all platforms that are not yet converted to DT, and we can have code that relies on DT checking for this symbol being disabled.

The multiplatform variant has a number of limitations at the moment: * It only supports DT-enabled machines. This is not a problem in the long run, as non-DT machines for exynos are going away. The main problem here is that the gpio code and the exynos_eint irqchip are not multiplatform capable but still required for ATAGS based boot. * The watchdog driver is still missing a conversion. * sparsemem and memory_holes are currently not supported in multiplatform. The the multiplatform aware ARCH_EXYNOS Kconfig symbol is disabled for now, as dependent patches are still pending in other subsystem trees. We will enable it once everything comes together.
