* x86: drop legacy (PC BIOS) boot in favor of EFIAhmad Fatoum2021-03-251-2/+0
| | | | | | | | | | | | | The 16-bit port has experienced bitrot and failed to compile with more recent linkers for at least a year. Fixing the linker error is insufficient to restore a barebox that can boot to shell. This continued breakage likely means that there are no users interested in updating. As new x86 projects should be using MACH_EFI_GENERIC anyway, retire support for 16-bit legacy boot (MACH_X86_GENERIC).

* common: drop done TODO about 4G partitionsAhmad Fatoum2021-03-251-1/+0
| | | | | | | | With recent changes, barebox can handle partitions bigger than 4G. Remove the todo. Signed-off-by: Ahmad Fatoum <a.fatoum@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* partitions: don't allocate dma capable memoryAhmad Fatoum2021-03-231-3/+2
| | | | | | | | | | | While block drivers may do DMA, they always use block caching chunks as bounce buffer. No dma is every done directly to the block_read data argument, so it doesn't need to be allocated with dma_alloc. The buffer also need not be zeroed, as block_read will either overwrite it completely or fail.

* block: use 64-bit types for sector offset and count on all platformsAhmad Fatoum2021-02-181-1/+1
| | | | | | | | | | | barebox' use of int for the sector offset puts an upper bound of 1TB on the size of supported block devices, which is already exceeded by common place USB mass storage. Increasing the sizes involved to 64 bit like Linux does won't magically add missing driver support, but it gives us at least a fighting chance. Do so.

* partition: include partuuid string in debug stringAhmad Fatoum2019-10-231-2/+2

* 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.

* cdev: Add partuuid string to struct cdevSascha Hauer2015-06-181-0/+1

* 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>
