grub2: fix build with BR2_STRIP_none

2016-07-31T18:19:40+00:00

grub2 assumes the strip command will generate output and the output should always be stripped - so, just use the $(TARGET_CROSS)strip to make sure that the build succeeds regardless of the buildroot strip configuration.

grub2: really disable liblzma

2016-06-15T21:01:18+00:00

There is no option --enable-liblzma=no in grub2's configure script, so the only way to disable liblzma support is to pass ac_cv_lib_lzma_lzma_code=no.

boot/grub2: add rootwait to default config

It doesn't hurt, and is useful for removable boot media like a pendrive that may depend on usb enumeration and isn't available immediately. Signed-off-by: Gustavo Zacarias Reviewed-by: Thomas Petazzoni Signed-off-by: Peter Korsgaard

grub2: pass target NM, OBJCOPY and STRIP

2015-09-20T12:52:19+00:00

Fixes https://bugs.busybox.net/show_bug.cgi?id=8256 grub2's build system interprets CC, CFLAGS and CPPFLAGS as for the host and uses TARGET_CC etc. for the target. However, NM, OBJCOPY and STRIP are used for the target. We currently pass the host-versions of these tools as part of $(HOST_CONFIGURE_OPTS). While we're at it, also pass TARGET_LDFLAGS. This problem had not been noticed up to now because usually we build on an x86 machine for the x86 architecture, so the binutils are compatible. However, this is not true on an i386 when building for x86_64. Cc: Christophe Bricout Signed-off-by: Arnout Vandecappelle (Essensium/Mind) Signed-off-by: Thomas Petazzoni

grub2: prepare and install El Torito image

2015-06-14T21:24:59+00:00

In order to support ISO9660 bootable images that rely on Grub 2, this commit modifies thr Grub 2 makefile to generate and install an El Torito image. Such an image is simply produced by concatenating the cdboot.img provided by Grub 2, and the Grub 2 image generated by Buildroot using grub-mkimage. Since this action is so simple and cost-free, we don't bother adding a Grub 2 sub-option for that, and simply generate the El Torito image unconditionally.
