sandbox: Add cpu files This is an initial implementation with all functions defined but not working. The lds file is very simple since we can mostly rely on the linker defaults. Signed-off-by: Simon Glass <sjg@chromium.org> 2011-09-26 14:10:39 +00:00			`#`

sandbox: eth: Add a bridge to a real network for sandbox Implement a bridge between U-Boot's network stack and Linux's raw packet API allowing the sandbox to send and receive packets using the host machine's network interface. This raw Ethernet API requires elevated privileges. You can either run as root, or you can add the capability needed like so: sudo /sbin/setcap "CAP_NET_RAW+ep" /path/to/u-boot Signed-off-by: Joe Hershberger <joe.hershberger@ni.com> Reviewed-by: Simon Glass <sjg@chromium.org> 2015-03-22 22:09:21 +00:00			`obj-$(CONFIG_ETH_SANDBOX_RAW) += eth-raw-os.o`
sandbox: Add SDL library for LCD, keyboard, audio SDL (Simple DirectMedia Layer - see www.libsdl.org) is a library which provides simple graphics and sound features. It works under X11 and also with a simple frame buffer interface. It is ideally suited to sandbox U-Boot since it fits nicely with the low-level feature set required by U-Boot. For example, U-Boot has its own font drawing routines, its own keyboard processing and just needs raw sound output. We can use SDL to provide emulation of these basic functions for sandbox. This significantly expands the testing that is possible with sandbox. Add a basic SDL library which we will use in future commits.

sandbox: fix compiling of cpu/os.c U-boot itself generally builds with -nostdinc. This is because the bootloader needs to be completely standalone. In the sandbox arch though, we need a little bit of code to glue the u-boot world to the host operating system, and we need to be able to access the host libc's headers in order to do so. Currently, we're using -I/usr/include to workaround the global -nostdinc, but that doesn't work for everyone and for all headers. Instead, let's filter out -nostdinc when building the os.c code. Without this patch, some distros hit errors such as: ---8<--- In file included from /usr/include/fcntl.h:27:0, from os.c:22: /usr/include/features.h:323:26: fatal error: bits/predefs.h: No such file or directory --->8--- Signed-off-by: Andreas Bießmann <biessmann@corscience.de> Signed-off-by: Mike Frysinger <vapier@gentoo.org> 2011-12-02 10:53:13 +00:00			`# os.c is build in the system environment, so needs standard includes`
kbuild: use Linux Kernel build scripts Now we are ready to switch over to real Kbuild. This commit disables temporary scripts: scripts/{Makefile.build.tmp, Makefile.host.tmp} and enables real Kbuild scripts: scripts/{Makefile.build,Makefile.host,Makefile.lib}. This switch is triggered by the line in scripts/Kbuild.include -build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build.tmp obj +build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build obj We need to adjust some build scripts for U-Boot. But smaller amount of modification is preferable. Additionally, we need to fix compiler flags which are locally added or removed. In Kbuild, it is not allowed to change CFLAGS locally. Instead, ccflags-y, asflags-y, cppflags-y, CFLAGS_$(basetarget).o, CFLAGS_REMOVE_$(basetarget).o are prepared for that purpose.
