Subject: [PATCHv3] Rework of handling disk like media
Date: Thu, 24 Nov 2011 13:43:38 +0100	[thread overview]
Message-ID: <1322138631-8963-1-git-send-email-jbe@pengutronix.de> (raw)

This patch stack reworks the handling of disk like media (hard disks, USB mass
storage, SD/MMC cards). It should simplify the code by using the generic
blockdevice layer.
Also partition handling is now a separate step to provide more partition types
than the D*S one in the future.
At the end of this series support for a subset of ATA devices and their
interface is added.

Update: This series contains fixed and improved versions of the patches
08/13, 09/13 and 12/13.
An additional fix in 08/13 was made, due to a broken disk size guessing for
x86.

Comments are welcome.

Juergen Beisert (13):
      USB Mass Storage driver: Fix compile time warning
      Create a unique cdev number for on demand devices
      ATA/DISK: Add generic disk support when enabling the BIOS disk driver
      ATA/DISK: Enabling write support does not belong to 'drive types'
      ATA/DISK: Reorganize file structure and names for future updates
      ATA/DISK: The BIOS based disk driver is not an interface
      ATA/DISK: Share important constants and structures
      DISK: Add common partition handling for disk like media
      Use generic block layer to access the drives and do partition parsing
      Remove 'disk_drive.c' as it is now replaced by generic partition handling
      ATA/DISK: Remove the now unused header <ata.h>
      ATA Disk Support: Add support for native ATA type drives
      Add driver for IDE like interfaces
