2023-08-25uuid: Add ChromiumOS partition typesSimon Glass
Add some GUIDs for ChromiumOS so we can detect the partitions. Signed-off-by: Simon Glass <sjg@chromium.org>
2021-01-16doc/README.gpt: define partition type GUID for U-Boot environmentRasmus Villemoes
When setting aside a GPT partition for holding the U-Boot environment, having a partition type GUID [1] indicating "Linux filesystem" (as most tools default to) is somewhat misleading - and there's no other well-known type GUID that is better suited. So to have a canonical value to put into the type field, define 3de21764-95bd-54bd-a5c3-4abe786f38a8 to mean a partition holding a U-Boot environment. This is a v5 namespace-name GUID [2], generated [3] from a namespace of "25cbcde0-8642-47c6-a298-1a3a57cd256b" and name "U-Boot environment". Should future type GUIDs be defined in the context of U-Boot, it's sensible to use that same namespace GUID.

2019-08-23disk: efi: ignore 'IGNOREME' GPT header found on cros eMMCsUrja Rannikko
Some ChromeOS devices (atleast veyron speedy) have the first 8MiB of the eMMC write protected and equipped with a dummy 'IGNOREME' GPT header - instead of spewing error messages about it, just silently try the backup GPT. Note: this does not touch the gpt cmd writing/verifying functions, those will still complain. Signed-off-by: Urja Rannikko <urjaman@gmail.com> Reviewed-by: Kever Yang <kever.yang@rock-chips.com>
2018-10-09Rename GPT_HEADER_SIGNATURE to avoid conflictSimon Glass
The current name conflicts with the Chrome OS verified boot library, which prevents it being built. That library uses a string whereas U-Boot uses a 64-bit hex value. Rename this in U-Boot. Signed-off-by: Simon Glass <sjg@chromium.org>
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>
2017-12-07part: efi: Add a Kconfig option for the number of partition entriesMaxime Ripard
On some SoCs, the SPL needs to be located right in the middle of the GPT partition entries. One way to work around that is to create partition entries for a smaller number of partitions to accomodate with where the SPL will be. Create a Kconfig option to allow to do that.

2015-11-12part:efi: add GUID for linux file system dataPatrick Delaunay
Previously, Linux used the same GUID for the data partitions as Windows (Basic data partition: EBD0A0A2-B9E5-4433-87C0-68B6B72699C7). This created problems when dual-booting Linux and Windows in UEFI-GPT Setup, so a new GUID (Linux filesystem data: 0FC63DAF-8483-4772-8E79-3D69D8477DE4) was defined jointly by GPT fdisk and GNU Parted developers.

2015-08-05efi: Add start-up library codeSimon Glass
When running as an EFI application, U-Boot must request memory from EFI, and provide access to the boot services U-Boot needs. Add library code to perform these tasks. This includes efi_main() which is the entry point from EFI. U-Boot is built as a shared library. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
