Old bootloader (same ones which have DT disabled) don't perform any PCIe initialization. The consequence is a freeze during PCIe bring-up on these old u-boot. Same kernel with a newer bootloaders works fine as they contain the corresponding PCIe init code. In this change, we'll add the missing init and make sure the kernel doesn't rely on some preexisting init to get PCIe to work. That includes the following changes: *GPIOs: set function & drive strength *Clocks: add init code for aux & ref clocks *PCIe driver: additional init of the hardware controller Tested 3.18 and 4.1 on an AP148 with bootloader branch 0.0.1 Signed-off-by: Mathieu Olivari <mathieu@codeaurora.org> SVN-Revision: 46557
This is the buildsystem for the OpenWrt Linux distribution. Please use "make menuconfig" to configure your appreciated configuration for the toolchain and firmware. You need to have installed gcc, binutils, bzip2, flex, python, perl, make, find, grep, diff, unzip, gawk, getopt, subversion, libz-dev and libc headers. Run "./scripts/feeds update -a" to get all the latest package definitions defined in feeds.conf / feeds.conf.default respectively and "./scripts/feeds install -a" to install symlinks of all of them into package/feeds/. Use "make menuconfig" to configure your image. Simply running "make" will build your firmware. It will download all sources, build the cross-compile toolchain, the kernel and all choosen applications. You can use "scripts/flashing/flash.sh" for remotely updating your embedded system via tftp. The OpenWrt system is documented in docs/. You will need a LaTeX distribution and the tex4ht package to build the documentation. Type "make -C docs/" to build it. To build your own firmware you need to have access to a Linux, BSD or MacOSX system (case-sensitive filesystem required). Cygwin will not be supported because of the lack of case sensitiveness in the file system. Sunshine! Your OpenWrt Project http://openwrt.org
