2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini1-2/+1
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>

2017-11-06disk: part_dos: fix part_get_info_extended() functionShawn Guo1-1/+1
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. $ fastboot flash mmcsda5 cache.img target reported max download size of 536870912 bytes sending 'mmcsda5' (18796 KB)...

2017-09-18EFI: find EFI system partition by legacy MBR partition typeAndre Przywara1-1/+1
The UEFI spec allows an EFI system partition (ESP, with the bootloader or kernel EFI apps on it) to reside on a disk using a "legacy" MBR partitioning scheme. But in contrast to actual legacy disks the ESP is not marked as "bootable" using bit 7 in byte 0 of the legacy partition entry, but is instead using partition *type* 0xef (in contrast to 0x0b or 0x0c for a normal FAT partition). The EFI spec isn't 100% clear on this, but it even seems to discourage the use of the bootable flag for ESPs. Also it seems that some EFI implementations (EDK2?) even seem to ignore partitions marked as bootable (probably since they believe they contain legacy boot code). The Debian installer [1] (*not* mini.iso), for instance, contains such an MBR, where none of the two partitions are marked bootable, but the ESP has clearly type 0xef. Now U-Boot cannot find the ESP on such a disk (USB flash drive) and fails to load the EFI grub and thus the installer. Since it all boils down to the distro bootcmds eventually calling "part list -bootable" to find potential boot partitions, it seems logical to just add this "partition type is 0xef" condition to the is_bootable() implementation. This allows the bog standard arm64 Debian-testing installer to boot from an USB pen drive on Allwinner A64 boards (Pine64, BananaPi-M64). (Ubuntu and other distribution installers don't have a legacy MBR, so U-Boot falls back to El Torito there).

2016-10-01disk: part: implement generic function part_get_info_by_name()Petr Kulhavy1-0/+1
So far partition search by name has been supported only on the EFI partition table. This patch extends the search to all partition tables. Rename part_get_info_efi_by_name() to part_get_info_by_name(), move it from part_efi.c into part.c and make it a generic function which traverses all part drivers and searches all partitions (in the order given by the linked list). For this a new variable struct part_driver.max_entries is added, which limits the number of partitions searched. For EFI this was GPT_ENTRY_NUMBERS. Similarly the limit is defined for DOS, ISO, MAC and AMIGA partition tables.

2016-03-14dm: part: Convert partition API use to linker listsSimon Glass1-1/+8
We can use linker lists instead of explicitly declaring each function. This makes the code shorter by avoiding switch() statements and lots of header file declarations. While this does clean up the code it introduces a few code issues with SPL. SPL never needs to print partition information since this all happens from commands. SPL mostly doesn't need to obtain information about a partition either, except in a few cases. Add these cases so that the code will be dropped from each partition driver when not needed. This avoids code bloat. I think this is still a win, since it is not a bad thing to be explicit about which features are used in SPL. But others may like to weigh in.

2013-05-01disk/part_dos: check harder for partition tableEgbert Eich1-3/+16
Devices that used to have a whole disk FAT filesystem but got then partitioned will most likely still have a FAT or FAT32 signature in the first sector as this sector does not get overwritten by a partitioning tool (otherwise the tool would risk to kill the mbr). The current partition search algorithm will erronously detects such a device as a raw FAT device. Instead of looking for the FAT or FAT32 signatures immediately we use the same algorithm as used by the Linux kernel and first check for a valid boot indicator flag on each of the 4 partitions. If the value of this flag is invalid for the first entry we then do the raw partition check. If the flag for any higher partition is wrong we assume the device is neiter a MBR nor PBR device.

2012-10-08disk: part_dos: don't claim whole-disk FAT filesystemsStephen Warren1-12/+9
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.
