From 23da43ae124fb5a0cc7254a4e23936610c0e15ec Mon Sep 17 00:00:00 2001 From: "Yann E. MORIN" Date: Sat, 10 Jan 2015 14:14:57 +0100 Subject: [PATCH] configs: add a DT-enabled Raspberry Pi defconfig This is an example of a Device-Tree-enabled Raspberry Pi defconfig. We have to use a 3.18-based kernel for that, but there are a few limitations: - we can not use the minimalist RPi defconfig bundled with the kernel, namely bcmrpi_quick_defconfig, because it is not DT-enabled, and sets CONFIG_ARM_PATCH_PHYS_VIRT to 'n', which prompts a value for CONFIG_PHYS_OFFSET, as it as no default for the bcm familly; - most importantly, the rpi-3.18.y branch is constantly rebased, so there is no guarantee that the sha1 I use today will still be usable in the long term. Using the name of hte branch is not better either. So, we bundle our own DT-enabled linux defconfig that is based on bcmrpi_quick_defconfig, with just CONFIG_ARM_PATCH_PHYS_VIRT set and the Device TRee enabled. Signed-off-by: "Yann E.
