grub: replace string option for filesystem selection by booleans

2013-12-29T11:17:46+00:00

In 1cece2813bf635ae29e9a8287322439b9c5992f7 (grub: add option to configure the list of supported filesystems), we introduced the BR2_TARGET_GRUB_FS_SUPPORT option which allows to provide a space-separated list of filesystems that Grub should support. However, it turns out that this not very practical, because the iso9660 filesystem logic in Buildroot should force the ISO9660 support to be enabled in Grub, which is not easy to do with a string option. Therefore, this patch changes this option from a string option to a list of boolean option, one per filesystem supported. A few useful details: - Since Grub legacy is dead, the list of filesystem, and therefore the number of options, will not grow. - We have only added options for filesystems that are likely to be used in an embedded Linux context. Filesystems such as VSTAfs, Minix, UFS2 or FFS2 are not supported. - There is no need to add some Config.in.legacy support for the previous option, since it was added after Buildroot 2013.11, and was therefore never part of an official Buildroot release.

In preparation to a change to the configuration options of the supported filesystem in Grub, enclose the network driver options in a sub-menu. Signed-off-by: Thomas Petazzoni Acked-by: "Yann E. MORIN"

grub: improve help text with detailed instructions to install grub

2013-12-01T22:45:07+00:00

These instructions should probaby go in the Buildroot manual, but at this point, it's not clear in which section they should go. So in order to not loose those notes, add them to the Grub help text. Signed-off-by: Thomas Petazzoni Signed-off-by: Peter Korsgaard

grub: add option to configure the list of supported filesystems

2013-12-01T22:44:13+00:00

Grub can be configured to enable or disable the filesystems supported in the stage 2. In addition, there are filesystem specific stage 1.5. In order to save space and build time, we provide a new option that allows to give a space-separated list of filesystems that Grub should support. We default to support FAT and ext2, since most of the other filesystems are fairly unlikely to be used. We use this option to: 1) Pass --enable- or --disable-, which enables/disables the support of in Grub stage 2. 2) Install only the stage 1.5 that correspond to the selected filesystems.

grub: support build on x86-64, and misc other improvements

2013-12-01T22:35:28+00:00

This commit brings a number of improvements to the grub packaging: * It builds grub with the host compiler, which is needed so that we can build a 32 bits grub even if the target architecture is x86-64. To make sure we have a host compiler capable of generating 32 bits code, grub now selects the BR2_HOSTARCH_NEEDS_IA32_COMPILER option. Building with the host compiler is done by cheating and passing $(HOST_CONFIGURE_OPTS) in GRUB_CONF_ENV. * Some additional CFLAGS are added to make sure grub builds properly with modern compilers (-O0, --build-id=none, -fno-stack-protector). * Removal of the GRUB_INSTALL_STAGING_CMDS which were not used, since GRUB_INSTALL_STAGING was not set to YES. * Installation of the "grub" binary in $(HOST_DIR) instead of $(TARGET_DIR) since it's actually used only on the host to install grub into an image or device. * Removal of the grub uninstall commands, since they are generally considered useless.

boot: get rid of toplevel submenus

Sub options are indented anyway, so no need for empty menus / force people to enter sub menus to see configuration options. Signed-off-by: Peter Korsgaard
