2018-06-14efi_loader: avoid initializer element is not constantHeinrich Schuchardt
When building with -pedantic the current definition of EFI_GUID() causes an error 'initializer element is not constant'. Currently EFI_GUID() is used both as an anonymous constant and as an intializer. A conversion to efi_guid_t is not allowable when using EFI_GUID() as an initializer. But it is needed when using it as an anonymous constant. We should not use EFI_GUID() for anything but an initializer. So let's introduce a variable where needed and remove the conversion.

2018-06-05disk: efi: Correct backing up the MBR boot codeSam Protsenko
In commit e163a931af34 ("cmd: gpt: backup boot code before writing MBR") there was added the procedure for storing old boot code when doing "gpt write". But instead of storing just backup code, the whole MBR was stored, and only specific fields were replaced further, keeping everything else intact. That's obviously not what we want. Fix the code to actually store only old boot code and zero out everything else. This fixes next testing case: => mmc write $loadaddr 0x0 0x7b => gpt write mmc 1 $partitions In case when $loadaddr address and further memory contains 0xff, the board was bricked (ROM-code probably didn't like partition entries that were clobbered with 0xff). With this patch applied, commands above don't brick the board.

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
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>

2018-04-16part: Disable CONFIG_SPL_ISO_PARTITION by defaultAlexander Graf
We enabled CONFIG_ISO_PARTITION by default for distro boot, so that U-Boot could load distro images that usually get shipped as iso images. These images usually come with a board agnostic boot environment. However, there is very little point in having ISO support enabled (for anyone really) in SPL, as the whole idea of SPL is to load U-Boot proper which again is board specific. So the fact that we enable ISO support in U-Boot proper does not mean at all that we want ISO support in U-Boot SPL. Hence, let's remove the Kconfig dependency. Along the way, let's also clean up all those default configs that disabled SPL ISO support. Signed-off-by: Alexander Graf <agraf@suse.de>

2017-11-06disk: part_dos: fix part_get_info_extended() functionShawn Guo
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 Przywara
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).

2017-09-03part: efi: Disable overlap checkMaxime Ripard
The current code checks that no partitions overlap with the GPT partition table using the offset of the first LBA usable for that partition. This works fine, unless you have a partition entry that is further away than it usually is and you want to create partitions in the gap between the GPT header and the GPT partition entries, for example to reflash a bootloader that needs to be set there. Rework the test to something a bit smarter that checks whether a partition would overlap with either the GPT header or the partition entries, no matter where it is on the disk. Partitions that do not have a start LBA specified will still start at the first LBA usable set in the GPT header, to avoid weird behaviours.

2017-03-20part_efi: support padding between the GPT header and partition entriesPhilipp Tomsich
Some architectures require their SPL loader at a fixed address within the first 16KB of the disk. To avoid an overlap with the partition entries of the EFI partition table, the first safe offset (in bytes, from the start of the device) for the entries can be set through CONFIG_EFI_PARTITION_ENTRIES_OFF (via Kconfig) When formatting a device with an EFI partition table, we may need to leave a gap between the GPT header (always in LBA 1) and the partition entries. The GPT header already contains a field to specify the on-disk location, which has so far always been set to LBA 2. With this change, a configurable offset will be translated into a LBA address indicating where to put the entries. Now also allows an override via device-tree using a config-node (see doc/device-tree-bindings/config.txt for documentation).
