part: efi: Add default number of partition entries for sunxi

2017-12-07T15:24:31+00:00

The SPL must be located at 8kB (16 sectors) offset. That's right in the
middle of the GPT, so we need to define a smaller amount of partitions to
accomodate for that location.

part: efi: Add a Kconfig option for the number of partition entries

2017-12-07T15:24:31+00:00

On some SoCs, the SPL needs to be located right in the middle of the GPT
partition entries.

One way to work around that is to create partition entries for a smaller
number of partitions to accomodate with where the SPL will be. Create a
Kconfig option to allow to do that.

disk: part_dos: fix part_get_info_extended() function

2017-11-06T14:59:01+00:00

The check in part_get_info_extended() for a successful partition
searching misses a condition for extended partition. In case of
(ext_part_sector == 0), we should anyway mark the partition as found,
even if it's an extended partition, i.e. (is_extended(pt->sys_ind) == 0).
Otherwise, the extended partition (type 0x0f) will never be identified,
and the following recursive call to part_get_info_extended() will get a
wrong 'part_num' and 'which_part' parameter.  In the end, all those
partitions in extended table will not be identified.

Let's add the missing OR condition of (ext_part_sector == 0) for
is_extended() check to fix the problem.

The issue is discovered by running fastboot flash to an extended
partition on eMMC.

gpt: Use cache aligned buffers for gpt_h and gpt_e

2017-11-06T14:59:01+00:00

Before this patch one could receive following errors when executing
"gpt write" command on machine with cache enabled:

display5 factory > gpt write mmc ${mmcdev} ${partitions}
Writing GPT:
CACHE: Misaligned operation at range [4ef8f7f0, 4ef8f9f0]
CACHE: Misaligned operation at range [4ef8f9f8, 4ef939f8]
CACHE: Misaligned operation at range [4ef8f9f8, 4ef939f8]
CACHE: Misaligned operation at range [4ef8f7f0, 4ef8f9f0]
success!

To alleviate this problem - the calloc()s have been replaced with
malloc_cache_aligned() and memset().

After those changes the buffers are properly aligned (with both start
address and size) to SoC cache line.

disk: efi: correct the overlap check on GPT header and PTE

2017-10-23T21:27:48+00:00

the partition starting at 0x4400 is refused with overlap error:
  $> gpt write mmc 0 "name=test,start=0x4400,size=0"
  Writing GPT: Partition overlap
  error!

even if the 0x4400 is the first available offset for LBA35 with default
value:
- MBR=LBA1
- GPT header=LBA2
- PTE= 32 LBAs (128 entry), 3 to 34

And the command to have one partition for all the disk failed also :
  $> gpt write mmc 0 "name=test,size=0"

After the patch :

  $> gpt write mmc 0 "name=test,size=0"
  Writing GPT: success!
  $> part list mmc 0

  Partition Map for MMC device 0  --   Partition Type: EFI

  Part	Start LBA	End LBA		Name
	Attributes
	Type GUID
	Partition GUID
  1	0x00000022	0x01ce9fde	"test"
	attrs:	0x0000000000000000
	type:	ebd0a0a2-b9e5-4433-87c0-68b6b72699c7
	type:	data
	guid:	b4b84b8a-04e3-4000-0036-aff5c9c495b1

And 0x22 = 34 LBA => offset = 0x4400 is accepted as expected

iso: Reduce verbosity on test and info calls

2017-10-16T13:42:51+00:00

The test and info callbacks into the partition callback struct are
used by the "part list" command on the command line. That command
is used by the distro script.

With verb=1 set, "part list" thus throws a lot of warnings about
partitions it can't find when an upper layer searches for partitions.

So let's reduce verbosity to bring it to the same level of noise
as the other partition targets.

part_efi: In is_gpt_valid() check argument validity before allocation

2017-10-16T13:42:51+00:00

While this goes somewhat against normal coding style we should ensure
that dev_desc is not NULL before we dereference it in allocation of
legacy_mbr.

disk: Provide API to get partition by name for specific type

2017-10-06T15:28:17+00:00

There is already existing function part_get_info_by_name().
But sometimes user is particularly interested in looking for only
specific partition type. This patch implements such an API that
provides partition searching by name for specified partition type.
