Felix Fietkau bdcba36442 ipq806x: fix boot freeze on zImage kernel ARCH_QCOM is using the ARCH_MULTIPLATFORM option, as now recommended on most ARM architectures. This automatically calculate ZRELADDR by masking PHYS_OFFSET with 0xf8000000. On IPQ806x though, the first ~20MB of RAM is reserved for the hardware. In newer bootloader, when DT is used, this is not a problem, we just reserve this memory in the device tree. But if the bootloader doesn't have DT support, then ATAGS have to be used. In this case, the ARM decompressor will position the kernel in this low mem, which will not be in the RAM section mapped by the bootloader, which means the kernel will freeze in the middle of the boot process trying to map the memory. As a work around, this patch allows disabling AUTO_ZRELADDR when ARCH_QCOM is selected. It makes the zImage usage possible on bootloaders which don't support device-tree, which is the case on certain early IPQ806x based designs.

README

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.
