| * Only pass -P to cpp when generating ld scriptsLoïc Minier2011-10-181-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When building sandbox with ccache, one would hit warnings such as: warning: 'struct mmsghdr' declared inside parameter list on random files; a way to reproduce this issue is to build a simple file doing just: #include <sys/socket.h> int main(void) { return 0; } gcc -Wall -P -c -o foo foo.c But actually the -P flag is only useful when generating non-C files, such as linker scripts in the case of barebox. Removing the -P flag from all the gcc invocations, except when generating .lds files makes the warning go away. It turns out that this is what linux/scripts/Makefile.build also does nowadays.

* Don't try to guess the size of a disk if its size value is already givenJuergen Beisert2010-10-111-1/+1
| | | | | | | | | | | | | | | | | Guessing the size of an attached harddisk (access via x86 BIOS) was needed due to the fact, barebox can't query this information from the BIOS easily. But with the SD/MMC cards, there will be a second user of the generic disk handling routines. And with this media it is very easy to know its size. This patch provides a workaround to keep the guessing feature if the size of the registered disk is 0. If it is not 0, the given value will be used instead. Note: This is in preparation to add MCI card support, which can be handled like a disk drive. Signed-off-by: Juergen Beisert <jbe@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
