2014-05-12disk: part_efi: add support for the Backup GPTSteve Rae
Check the Backup GPT table if the Primary GPT table is invalid. Renamed "Secondary GPT" to "Backup GPT" as per: UEFI Specification (Version 2.3.1, Errata A) Signed-off-by: Steve Rae <srae@broadcom.com>
2014-04-02lib: uuid: code refactor for proper maintain between uuid bin and stringPrzemyslaw Marczak
Changes in lib/uuid.c to: - uuid_str_to_bin() - uuid_bin_to_str() New parameter is added to specify input/output string format in listed functions This change allows easy recognize which UUID type is or should be stored in given string array. Binary data of UUID and GUID is always stored in big endian, only string representations are different as follows. String byte: 0 36 String char: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx string UUID: be be be be be string GUID: le le le be be This patch also updates functions calls and declarations in a whole code.

2014-04-02part_efi: move uuid<->string conversion functions into lib/uuid.cPrzemyslaw Marczak
This commit introduces cleanup for uuid library. Changes: - move uuid<->string conversion functions into lib/uuid.c so they can be used by code outside part_efi.c. - rename uuid_string() to uuid_bin_to_str() for consistency with existing uuid_str_to_bin() - add an error return code to uuid_str_to_bin() - update existing code to the new library functions.

2014-02-24part_efi: fix protective mbr struct allocationHector Palacios
The calloc() call was allocating space for the sizeof the struct pointer rather than for the struct contents. Besides, since this buffer is passed to mmc for writing and some platforms may use cache, the legacy_mbr struct should be cache-aligned.

2013-09-20part_efi: make sure the gpt_pte is freedMark Langsdorf
the gpt_pte wasn't being freed if it was checked against an invalid partition. The resulting memory leakage could make it impossible to repeatedly attempt to load non-existent files in a script. Also, downgrade the message for not finding an invalid partition from a printf() to a debug() so as to minimize message spam in perfectly normal situations.

2013-07-15Fix ext2/ext4 filesystem accesses beyond 2TiBFrederic Leroy
With CONFIG_SYS_64BIT_LBA, lbaint_t gets defined as a 64-bit type, which is required to represent block numbers for storage devices that exceed 2TiB (the block size usually is 512B), e.g. recent hard drives We now use lbaint_t for partition offset to reflect the lbaint_t change, and access partitions beyond or crossing the 2.1TiB limit. This required changes to signature of ext4fs_devread(), and type of all variables relatives to block sector. ext2/ext4 fs uses logical block represented by a 32 bit value. Logical block is a multiple of device block sector. To avoid overflow problem when calling ext4fs_devread(), we need to cast the sector parameter. Signed-off-by: Frédéric Leroy <fredo@starox.org>
2013-06-04disk: Fix possible out-of-bounds access in part_efi.cMarek Vasut
Make sure to never access beyond bounds of either EFI partition name or DOS partition name. This situation is happening: part.h: disk_partition_t->name is 32-byte long part_efi.h: gpt_entry->partition_name is 36-bytes long The loop in part_efi.c copies over 36 bytes and thus accesses beyond the disk_partition_t->name . Fix this by picking the shortest of source and destination arrays and make sure the destination array is cleared so the trailing bytes are zeroed-out and don't cause issues with string manipulation.

2012-10-17disk: part_efi: set bootable flag in partition objectsStephen Warren

When printing the partition table, print the partition type UUID and the individual partition UUID. Do this unconditionally, since partition UUIDs are useful. Signed-off-by: Stephen Warren <swarren@nvidia.com>
2012-10-17disk: part_efi: re-order partition list printf, change caseStephen Warren
The partition name is a long variable-length string. Move it last on the line to ensure consistent layout and that the entries align with the "header" line. Also, surround it in quotes, so if it's empty, it's obvious that something is still being printed. Also, change the case of the LBA numbers; lower-case looks nicer in my opinion, and will be more consistent with the UUID printing that is added later in this series. Signed-off-by: Stephen Warren <swarren@nvidia.com>
2012-10-17disk: part_efi: remove indent level from loopStephen Warren
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. Signed-off-by: Stephen Warren <swarren@nvidia.com>
2012-09-25disk: part_efi: parse and store partition UUIDStephen Warren
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(). Signed-off-by: Stephen Warren <swarren@nvidia.com>

2011-12-05disk: part_efi: fix regression due to incorrect buffer usageStephen Warren
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.

2011-10-27disk: part_efi: fix **pgpt_pte == NULLDoug Anderson
Code was setting **pgpt_pte == NULL, which meant that the pointer to the gpt_pte would be stored at RAM address 00000000.

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.

2009-04-03mflash: Initial mflash supportunsik Kim
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. Signed-off-by: unsik Kim <donari75@gmail.com>

2009-01-27part_efi: Fix partition size calculation due to inclusive ending LBA.Richard Retanubun
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.
