38a3021edc disk: part_efi: remove indent level from loop
Simplify the partition printing loop in print_part_efi() to bail out
early when the first invalid partition is found, rather than indenting
the whole body of the loop. This simplifies later patches.

894bfbbfb7 disk: part_efi: parse and store partition UUID
Each EFI partition table entry contains a UUID. Extend U-Boot's struct
disk_partition to be able to store this information, and modify
get_partition_info_efi() to fill it in.

The implementation of uuid_string() was derived from the Linux kernel,
tag v3.6-rc4 file lib/vsprintf.c function uuid_string().

c04d68c694 disk: part_efi: range-check partition number
Enhance get_partition_info_efi() to range-check the partition number.
This prevents invalid partitions being accessed, and prevents access
beyond the end of the gpt_pte[] array.

4715a81136 disk: part_efi: fix regression due to incorrect buffer usage
Commit deb5ca8027 "disk: part_efi: fix
**pgpt_pte == NULL" modified the code to pass "&gpt_head" to
is_gpt_valid() rather than the previous "gpt_head". However, gpt_head
is a pointer to the buffer, not the actual buffer, since it was allocated
using ALLOC_CACHE_ALIGN_BUFFER. This caused is_gpt_valid() to read the
disk block onto the stack rather than into the buffer, causing the
code to fail.

This change reverts that portion of the commit mentioned above.

deb5ca8027 disk: part_efi: fix **pgpt_pte == NULL
Code was setting **pgpt_pte == NULL, which meant that the pointer
to the gpt_pte would be stored at RAM address 00000000. This 'worked'
on T20 (SDRAM starts @ 0x00000000), but hung gpt/EFI access on T30
(SDRAM starts @ 0x80000000).

f75dd584cd part_efi: dcache: allocate cacheline aligned buffers
Currently part_efi.c allocates buffers for the gpt_header, the
legacy_mbr, and the pte (partition table entry) that may be
incorrectly aligned for DMA operations.

This patch uses ALLOC_CACHE_ALIGN_BUFFER for the stack allocated
buffers and memalign to replace the malloc of the pte.

6eecc03079 part: show efi partition name when print out partition info
Previous output:
Marvell>>  mmc part

Partition Map for MMC device 1  --   Partition Type: EFI

Part  Start LBA  End LBA
gpt1  0x8C00    0xCBFF

gpt3  0x57C00    0xA2BFF
gpt4  0xA2C00    0xECBFDE

With the patch, the output becomes:

75eb82ec7c mflash: Initial mflash support
Mflash is fusion memory device mainly targeted consumer eletronic and
mobile phone.
Internally, it have nand flash and other hardware logics and supports
some different operation (ATA, IO, XIP) modes.

IO mode is custom mode for the host that doesn't have IDE interface.
(Many mobile targeted SoC doesn't have IDE bus)

This driver support mflash IO mode.

Followings are brief descriptions about IO mode.

1. IO mode based on ATA protocol and uses some custom command. (read
   confirm, write confirm)
2. IO mode uses SRAM bus interface.

5097083971 part_efi: Fix partition size calculation due to inclusive ending LBA.
The ending LBA is inclusive. Hence, the partition size should be
((ending-LBA + 1) - starting-LBA) to get the proper partition size.

This is confirmed against the results from the parted tool.
(e.g. use parted /dev/sda -s unit S print) and observe the size.
