* of: partitions: flag partitions from a partition tableSascha Hauer2017-03-311-0/+2
| | | | | | | | | We are going to call the of_partition_fixup for regular block devices like MMC/SD aswell. Add a flag to partitions indicating they are instanciated from a on-disk partition table so that they won't be added as device tree partitions during fixup.

* string: Fix (v)asprintf prototypesSascha Hauer2016-04-151-1/+1
| | | | | | | | | | Our asprintf and vasprintf have different prototypes than the glibc functions. This causes trouble when we want to share barebox code with userspace code. Change the prototypes for (v)asprintf to match the glibc prototypes. Since the current (v)asprintf are convenient to use change the existing functions to b(v)asprintf.

* partition: Create links with partition namesSascha Hauer2016-01-081-13/+7
| | | | | | | When a partition has a name create a link to the original partition rather than registering a second cdev. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* cdev: Add partuuid string to struct cdevSascha Hauer2015-06-181-0/+1
| | | | | | | | 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>
* common: fix mbr filetype detectionZahari Doychev2014-11-051-0/+2
| | | | | | | | | | | | | | Sometimes mbr is erroneously recocognised as FAT partion. Due to this the mbr partition parser is not being called and the partitions on the media are not detected. This patch should fix the problem. The checking is done as in the linux kernel. I have seen the problem using usb sticks. Although partitioning and formatting them under linux. The file system type field in the mbr remains there which causes the wrong detections as FAT32 type and not as mbr.

* block: implement block_read/block_write functionsSascha Hauer2013-05-311-1/+1
| | | | | | | | | Some drivers use blk->ops->read/write. This bypasses the caching block layer and was never intended like this. The upper API to the block layer is the cdev layer. This patch adds block_read and block_write functions and uses them where appropriate. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* common/partition: check only for partition table typesHubert Feurstein2013-04-291-2/+2
| | | | | | | | The detection of the partition table fails when we have a barebox image in the MBR. So check only for partition table types. Signed-off-by: Hubert Feurstein <h.feurstein@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
