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.

raspberrypi, raspberrypi2: add a serial console The current Buildroot defconfigs for Raspberry Pi and Raspberry Pi 2 instantiate a console on tty1, which appears on HDMI. Add a console on the serial port (ttyAMA0) to be more consistent with other defconfigs and provide a better out-of-the-box experience to users used to have a serial console from Buildroot defconfigs. This requires three changes: 1. have two 'console=' entries in the kernel command line: tty1, then ttyAMA0; 2. change BR2_TARGET_GENERIC_GETTY_PORT to "console", so it starts a getty on the last console= passed to the kernel, ttyAMA0; 3. add a new getty on tty1 to the generated inittab. Step 2 is actually obtained by removing BR2_TARGET_GENERIC_GETTY_PORT entirely from the defconfigs, since "console" is the default value. Step 3 requires a post-build script since the Buildroot makefiles can configure only one console. Note: instead of simply adding a new getty on ttyAMA0 (which would work) this patch actually changes BR2_TARGET_GENERIC_GETTY_PORT to instantiate a console on UART, then adds back tty1 via post-build.sh. This is done only to avoid the "GENERIC_SERIAL" comment where we instantiate an HDMI console, then instantiate a really-serial console on another line. The result is these two inittab lines: console::respawn:/sbin/getty -L console 0 vt100 # GENERIC_SERIAL tty1::respawn:/sbin/getty -L tty1 0 vt100 # HDMI console Cc: Yann E.
