Dear Egbert Eich,
-----Original Message----- From: Egbert Eich [mailto:egbert.eich@gmail.com] Sent: Tuesday, April 09, 2013 5:12 PM To: u-boot@lists.denx.de Cc: Piotr Wilczek; Egbert Eich Subject: [Patch v2] cmd/gpt: Support gpt command for all devices
From: Egbert Eich eich@suse.com
The gpt command was only implemented for mmc devices. There is no reason why this command should not be generalized and be applied all other storage device classes. This change both simplifies the implementation and eliminates a build failure for systems that don't support mmcs.
Signed-off-by: Egbert Eich eich@suse.com
Changes for v2:
- Coding style cleanup.
