disk: define HAVE_BLOCK_DEVICE in a common place

2013-03-14T18:06:44+00:00

This set of ifdefs is used in a number of places. Move its definition
somewhere common so it doesn't have to be repeated.

disk: part_dos: print partition UUID in partition list

2012-10-17T14:59:11+00:00

This information may be useful to compare against command "part uuid",
or if you want to manually paste the information into the kernel
command-line.

Minor cleanups required so later patches don't trigger checkpatch.

disk: part_dos: don't claim whole-disk FAT filesystems

2012-10-08T18:15:04+00:00

Logically, a disk that contains a raw FAT filesystem does not in fact
have a partition table. However, test_part_dos() was claiming that such
disks did in fact have a DOS-style partition table. This caused
get_device_and_partition() not to return a whole-disk disk_partition_t,
since part_type != PART_TYPE_UNKNOWN.

part_dos.c's print_partition_extended() detected the raw FAT filesystem
condition and printed a fake partition table that encompassed the whole
disk.

However, part_dos.c's get_partition_info_extended() did not return any
valid partitions in this case. This combination caused
get_device_and_partition() not to find any valid partitions, and hence
to return an error.

Fix test_part_dos() not to claim that raw FAT filesystems are DOS
partition tables. In turn, this causes get_device_and_partition() to
return a whole-disk disk_partition_t, and hence the following commands
work:

fatls mmc 0 /
fatls mmc 0:auto /

An alternative would be to modify print_partition_extended() to detect
raw FAT filesystems, just like print_partition_extended() does, and to
return a fake partition in this case. However, this seems logically
incorrect, and also duplicates code, since get_device_and_partition()
falls back to returning a whole-disk partition when there is no partition
table on the device.

disk: part_msdos: parse and store partition UUID

2012-09-25T22:05:45+00:00

The MSDOS/MBR partition table includes a 32-bit unique ID, often referred
to as the NT disk signature. When combined with a partition number within
the table, this can form a unique ID similar in concept to EFI/GPT's
partition UUID.

This patch generates UUIDs in the format 0002dd75-01, which matches the
format expected by the Linux kernel.

disk/part: check bootable flag for DOS partitions

2012-09-25T21:43:19+00:00

Determine which partitions are bootable/active. In the partition listing,
print "Boot" for partitions with the bootable/active flag set.

part_dos: fix crash with big sector size

2011-07-27T21:41:33+00:00

Apple iPod nanos have sector sizes of 2 or 4 KiB, which crashes U-Boot when it
tries to read the MBR into 512-byte buffer situated on stack. Instead use the
variable length arrays to be safe with any large sector size.

FAT32: fix support for superfloppy-format (PBR)

2010-07-24T18:53:43+00:00

"Superfloppy" format (in U-Boot called PBR) did not work for FAT32 as
the file system type string is at a different location. Add support
for FAT32.
