From e45a1e18a57ccc2457429f3bd42d93330c0fee3c Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Thu, 17 Dec 2015 16:35:20 +0100 Subject: ARM: defconfig: use correct debug_ll settings The debug-ll infrastructure can be configured in two ways, either by selecting a platform specific debug option, or by picking one of the generic options (8250 or pl01x typically). For compatibility with multiplatform kernels, we have changed a couple of platforms to use the former method now when they used to use the latter. Unfortunately, this broke the defconfigs because now they still enable CONFIG_DEBUG_LL_UART_PL01X or CONFIG_DEBUG_LL_UART_8250, and we no longer configure the correct register addresses automatically. Embarrassingly, this was only found in linux-next when the defconfig builds turned up errors for multiple people, and I had not caught those in my own tests, which were done using the randconfig fixes patchset on top, and that has a workaround to avoid a build error when the addresses are not configured. The error was something like: .config:2010:warning: symbol value '' invalid for DEBUG_UART_PHYS .config:2011:warning: symbol value '' invalid for DEBUG_UART_VIRT This patch avoids the problem by removing the respective statements from the defconfig files. Any out of tree defconfig files on the platforms I have changed will have to do the same change or run into the build error above. Any users that have a full .config already set the correct DEBUG_UART_PHYS/VIRT addresses and do not need to change anything.
