disk: efi: ignore 'IGNOREME' GPT header found on cros eMMCs

2019-08-23T10:15:50+00:00

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.

Rename GPT_HEADER_SIGNATURE to avoid conflict

2018-10-09T10:40:27+00:00

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.

disk: efi: Correct backing up the MBR boot code

2018-06-05T14:33:57+00:00

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.

SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12+00:00

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.

part: efi: Add a Kconfig option for the number of partition entries

2017-12-07T15:24:31+00:00

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.

part:efi: add GUID for linux file system data

2015-11-12T20:58:57+00:00

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.

efi: Add start-up library code

2015-08-05T14:42:41+00:00

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.
