part_efi: Fix compile errors

Fix errors noticed after enabling CONFIG_EFI_PARTITION
for the OMAP3 EVM board:

disk: part_efi: fix regression due to incorrect buffer usage

2011-12-05T21:23:21+00:00

Commit deb5ca80275e8cfa74d5680b41204e08a095eca5 "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.

disk: part_efi: fix **pgpt_pte == NULL

2011-10-27T21:53:59+00:00

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).

part_efi: dcache: allocate cacheline aligned buffers

2011-10-25T07:26:34+00:00

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.

part: show efi partition name when print out partition info

2011-10-06T18:42:47+00:00

Previous output:
Marvell>>  mmc part

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

Part  Start LBA  End LBA
gpt1  0x8C00    0xCBFF
gpt2  0xCC00    0x57BFF
gpt3  0x57C00    0xA2BFF
gpt4  0xA2C00    0xECBFDE

With the patch, the output becomes:

mflash: Initial mflash support

2009-04-03T21:47:06+00:00

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.

Move the CONFIG_XXX out of the part_XXX.c file and into Makefile to

part_efi: Fix partition size calculation due to inclusive ending LBA.

2009-01-27T22:03:57+00:00

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.
