This reverts commit 9e467a764b4e30a04dd0431ea277f6acd26babe0. The Raspberry Pi firmware recently switched to building from the common firmware branch. This introduces changes in the core clock handling, causing various issues. E.g. enable_uart=1 no longer fixes the core clock frequency to 250MHz. When the disable-bt DT overlay is not loaded, the core clock frequency is increased to 400MHz. As a result, the UART baud rate is no longer correct, and this causes garbled serial console, or communication problems with HATs that use the UART. As a workaround, the core clock could be fixed to 250MHz by adding 'core_freq=250' in /boot/config.txt, but as there appear to be other issues than just the UART being broken, the safer bet is to revert the firmware for now.

-----------------------------------------------------
This is the buildsystem for the OpenWrt Linux distribution.
To build your own firmware you need a Linux, BSD or MacOSX system (case
sensitive filesystem required). Cygwin is unsupported because of the lack
of a case sensitive file system.
You need gcc, binutils, bzip2, flex, python3.5+, perl, make, find, grep, diff,
unzip, gawk, getopt, subversion, libz-dev and libc headers installed.
1. Run "./scripts/feeds update -a" to obtain all the latest package definitions
defined in feeds.conf / feeds.conf.default
2. Run "./scripts/feeds install -a" to install symlinks for all obtained
packages into package/feeds/
3. Run "make menuconfig" to select your preferred configuration for the
toolchain, target system & firmware packages.
4. Run "make" to build your firmware. This will download all sources, build
the cross-compile toolchain and then cross-compile the Linux kernel & all
chosen applications for your target system.
