* cdev: Add partuuid string to struct cdevSascha Hauer2015-06-181-0/+4
| | | | | | | | This adds the partuuid string to struct cdev in order to have this available for constructing a suitable Linux root=PARTUUID= option for booting Linux. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* partitions: dos: parse extended partitionUwe Kleine-König2013-11-081-1/+75
| | | | | | | | DOS MBRs might contain an extended partition that holds several logical partitions. Add these to the partitions of the block device. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* partitions: dos: improve guess of disk sizeUwe Kleine-König2013-11-081-5/+9
| | | | | | | | | | | | The code used to ineffectively take the end of the last partition as guess for the disk size. Better use the end of the partition that has its end rearmost. Also return an unsigned type instead of int as the result is always non-negative. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* partition: DOS: Add parameter for the NT disk SignatureSascha Hauer2013-06-021-0/+88
| | | | | | | | | | The NT disk Signature is a unique 32-bit value in the MBR allowing to identify a MSDOS partitioned disk. The signature can be used to specify the Linux rootfs. This patch adds support for the NT disk Signature in the form of a device parameter which can both be read and written. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* disk: introduce partition nameJean-Christophe PLAGNIOL-VILLARD2013-02-161-1/+1
