Over a year ago in a commit ac96a1665ac7 ("bcm53xx: update Disable MMU and Dcache during decompression") we switched to Florian's patch for workarounding CFE bug. The main difference was using a part of existing __armv7_mmu_cache_flush instead of implementing flushing separately. This worked well for Northstar devices but doesn't work for BCM53573 as these devices simply don't start booting with Florian's patch. It's because of the ldmfd ASM instruction in the __armv7_mmu_cache_flush. So this commit switches back to using standalone implementation. This time instead of copying Broadcom's copy of cache-v7.S, we just make a copy of the original file on our own. Unfortunately we can't cross-dir compile cache-v7.S from ../../mm/ as that one also adds __INITDATA with define_cache_functions v7 which would just trigger > Error: unrecognized/unsupported machine ID (r1 = 0x0000007f). The only real change Broadcom did in copied .S file was modifying mcr instruction to use c6 instead of c14. It isn't clear to me if we really need it, but let's use it for now. By the way we also update commit message of the [PATCH] ARM: BCM5301X: Disable MMU and Dcache during decompression This makes kernel booting on BCM53573 successfully.

This is the buildsystem for the LEDE Linux distribution. Please use "make menuconfig" to choose your preferred 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. 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 LEDE Community http://www.lede-project.org
