This patch updates the csky custom external toolchain to fix a broken host dependency of gdb on libexpat.so.0 (most hosts now ship libexpat.so.1). gdb is required to copy and and boot the kernel (see board/csky/readme.txt). The updated gdb no longer has this host dependency, which solves the issue. Since this external toolchain was built and tested with csky kernel 4.9.56, this patch also updates to that kernel version. Finally, this 4.9.56 csky kernel changed its default bootargs. So we add a patch to preserve the same behavior as the previous version.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on Freenode IRC.
