From: Mark Rutland Date: Thu, 23 Oct 2014 15:33:33 +0000 (+0100) Subject: efi: efi-stub: notify on DTB absence X-Git-Tag: omap-for-v3.19/fixes-for-merge-window~18^2~60^2 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=0bcaa9040d058684d58c36ef273b8946996c7078;p=pandora-kernel.git efi: efi-stub: notify on DTB absence In the absence of a DTB configuration table, the EFI stub will happily continue attempting to boot a kernel, despite the fact that this kernel may not function without a description of the hardware. In this case, as with a typo'd "dtb=" option (e.g. "dbt=") or many other possible failures, the only output seen by the user will be the rather terse output from the EFI stub: EFI stub: Booting Linux Kernel... To aid those attempting to debug such failures, this patch adds a notice when no DTB is found, making the output more helpful: EFI stub: Booting Linux Kernel... EFI stub: Generating empty DTB Additionally, a positive acknowledgement is added when a user-specified DTB is in use: EFI stub: Booting Linux Kernel... EFI stub: Using DTB from command line Similarly, a positive acknowledgement is added when a DTB from a configuration table is in use: EFI stub: Booting Linux Kernel... EFI stub: Using DTB from configuration table Signed-off-by: Mark Rutland Acked-by: Leif Lindholm Acked-by: Ard Biesheuvel Acked-by: Roy Franz Acked-by: Matt Fleming Signed-off-by: Ard Biesheuvel --- Reading git-diff-tree failed
