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: 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`
sandbox: Use system headers first for sandbox's os.c This file must be compiled with system headers, even if U-Boot has headers of the same name. The existing solution for this is good enough for libfdt, but fails when we have headers like stdint.h in U-Boot. Use -idirafter instead of -I, and remove the -nostdinc and other things that we don't want for this file. The best way to do this is to keep a copy of the original flags, rather than trying to filter them later.
