* partitions: dos: add partuuid string for logical partitionsUwe Kleine-König2016-05-101-2/+7
| | | | | | | | | | | Commit bc31d85c6e23 ("cdev: Add partuuid string to struct cdev") added partuuid strings for dos partitions but only for the (up to) four primary partitions. Do the same for the logical partitions. Their numbers start at 5 independently of the number of available primary partitions.

* include: move crc specific stuff to crc.hSascha Hauer2016-04-151-0/+1
| | | | | | | We have a crc.h, so move our crc function prototypes there to further cleanup common.h. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* partitions/efi: Add partuuid to partition descriptionTrent Piepho2016-01-082-0/+2
| | | | | | | | | | In commit bc31d85c6e23d724664e76bcfc3b2eda778012a3 the partition UUID was added to the partition struct and thence to the cdev(s) for the partition. But just for DOS partitions. Do this for GPT aka EFI partitions too. Signed-off-by: Trent Piepho <tpiepho@kymetacorp.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* cdev: Add partuuid string to struct cdevSascha Hauer2015-06-182-0/+5
| | | | | | | | 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/efi: Fix off-by-one error in 'last_lba'Andrey Smirnov2014-11-111-1/+1
| | | | | | | | LBAs are numbered starting from zero so the last LBA # would be equal to total number of blocks minus one. Signed-off-by: Andrey Smirnov <andrew.smirnov@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | This adds support for running barebox in an EFI environment on X86 PC hardware. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* Move efi.h to include/Sascha Hauer2014-07-141-1/+1
| | | | | | | With upcoming EFI payload support the efi.h file will diverge from the kernel, so move it from include/linux/ to include/ Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* treewide: remove address of the Free Software FoundationAntony Pavlov2014-06-111-4/+0
| | | | | | | | | | | | | | | | | | The FSF address has changed; The FSF site says that address is Free Software Foundation 51 Franklin Street, Fifth Floor Boston, MA 02110-1301 USA (see http://www.fsf.org/about/contact/) Instead of updating it each time the address changes, just drop it completely treewide.

* 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>
* partitions: Add missing depends on BLOCKSascha Hauer2013-06-021-0/+1
| | | | | | | The disk partitions use blockdevice functions, so add the corresponding depends on BLOCK. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* block: implement block_read/block_write functionsSascha Hauer2013-05-311-2/+2
| | | | | | | | | 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>
