buildroot中的grub打上ext4支持
需要使用这里的补丁
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=511121
ext4_support.diff
ext4_fix_variable_sized_inodes.diff
?
要注意打这两个补丁要放在最后
define GRUB_EXT4_PATCHES
??????? support/scripts/apply-patches.sh $(@D) $($(PKG)_DIR_PREFIX)/$(RAWNAME)/ext4/
endef
GRUB_POST_PATCH_HOOKS += GRUB_DEBIAN_PATCHES
GRUB_POST_PATCH_HOOKS += GRUB_EXT4_PATCHES
