disk: part: align buffer so it can be used with DMA enabled drivers

2017-08-26T18:56:15+00:00

When using ISO partitions with a DMA enabled block device driver
reading the ISO partition leads to unaligned DMA operations:
  CACHE: Misaligned operation at range [bffb7da8, bffb85a8]

Align the buffer to make sure we pass a buffer which works for
DMA operations.

env: Rename getenv/_f() to env_get()

2017-08-16T12:30:24+00:00

We are now using an env_ prefix for environment functions. Rename these
two functions for consistency. Also add function comments in common.h.

Quite a few places use getenv() in a condition context, provoking a
warning from checkpatch. These are fixed up in this patch also.

GPT: add accessor function for disk GUID

2017-08-04T13:56:04+00:00

In order to read the GPT, modify the partition name strings, and then
write out a new GPT, the disk GUID is needed.  While there is an
existing accessor for the partition UUIDs, there is none yet for the
disk GUID.

Changes since v6: none.

partitions: increase MAX_SEARCH_PARTITIONS and move to part.h

2017-08-04T13:56:03+00:00

Move MAX_SEARCH_PARTITIONS to part.h so that functions in cmd
directory can find it.  At the same time, increase the value to
64 since some operating systems use many, and the resources
consumed by a larger value are minimal.

Changes since v6: none.

disk: Return the partition number in part_get_info_by_name()

2017-05-12T02:03:37+00:00

Similar to what blk_get_device_part_str() does, this patch makes
part_get_info_by_name() return the partition number in case of a match.
This is useful when the partition number is needed and not just the
descriptor.

part_efi: support padding between the GPT header and partition entries

2017-03-20T22:04:18+00:00

Some architectures require their SPL loader at a fixed address within
the first 16KB of the disk. To avoid an overlap with the partition
entries of the EFI partition table, the first safe offset (in bytes,
from the start of the device) for the entries can be set through
CONFIG_EFI_PARTITION_ENTRIES_OFF (via Kconfig)

When formatting a device with an EFI partition table, we may need to
leave a gap between the GPT header (always in LBA 1) and the partition
entries. The GPT header already contains a field to specify the
on-disk location, which has so far always been set to LBA 2. With this
change, a configurable offset will be translated into a LBA address
indicating where to put the entries.

Now also allows an override via device-tree using a config-node (see
doc/device-tree-bindings/config.txt for documentation).

Tested (exporting an internal MMC formatted with this) against Linux,
MacOS X and Windows.
