*	brcm63xx: add linux 4.4 support	Jonas Gorski	2015-12-02	1	-0/+169
	Only netboot tested. Flash at your own risk. Signed-off-by: Jonas Gorski <jogo@openwrt.org> git-svn-id: svn://svn.openwrt.org/openwrt/trunk@47702 3c298f89-4303-0410-b956-a3cf2f4a3e73

/* Name: bootloaderconfig.h * Micronucleus configuration file. * This file (together with some settings in Makefile.inc) configures the boot loader * according to the hardware. * * Controller type: ATtiny 841 - 12 MHz * Configuration: Default configuration * USB D- : PB0 * USB D+ : PB1 * Entry : Always * LED : PB2, Active Low * OSCCAL : Revert to precalibrated value (8 MHz) * Note: can use 12 MHz V-USB without PLL due to stable RC-osc in ATTiny841 * Flash write time may be too * Last Change: Mar 16,2014 * * License: GNU GPL v2 (see License.txt */ #ifndef __bootloaderconfig_h_included__ #define __bootloaderconfig_h_included__ /* ------------------------------------------------------------------------- */ /* Hardware configuration. */ /* Change this according to your CPU and USB configuration */ /* ------------------------------------------------------------------------- */ #define USB_CFG_IOPORTNAME B /* This is the port where the USB bus is connected.
