1.
commit dbcf1e3cc079d2f1b3df6c4c9ec3a34d0c05eb4c
Author: Luo Ji
Date: Fri Jun 8 10:31:11 2018 +0800[iot] Support dual bootloader in SPL
Move the A/B slot check to SPL, the A/B slot switch
workflow is just like what we have in libavb_ab.Test: A/B select works fine on imx8m.
2.
commit 71562aae3b8123ccd7503e596e478951568fcd24
Author: Ji Luo
Date: Mon Jan 14 18:28:08 2019 +0800MA-13938 [Android] imx8q: Support dual bootloader feature
Support dual bootloader feature for imx8q which uses the
container format. Move the A/B slot select and verify to
SPL stage, the bootloader rollback index will be stored
at the last 8K bytes of eMMC rpmb storage.Test: Boot and rbindex verify pass on imx8q.

In int-ll64.h, we always use the following typedefs:
typedef unsigned int u32;
typedef unsigned long uintptr_t;
typedef unsigned long long u64;This does not need to match to the compiler's .
Do not include it.The use of PRI* makes the code super-ugly. You can simply use
"l" for printing uintptr_t, "ll" for u64, and no modifier for u32.Signed-off-by: Masahiro Yamada

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.Signed-off-by: Heinrich Schuchardt

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 $partitionsIn 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.Signed-off-by: Sam Protsenko

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

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

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

The test and info callbacks into the partition callback struct are
used by the "part list" command on the command line. That command
is used by the distro script.With verb=1 set, "part list" thus throws a lot of warnings about
partitions it can't find when an upper layer searches for partitions.So let's reduce verbosity to bring it to the same level of noise
as the other partition targets.Signed-off-by: Alexander Graf

U-Boot widely uses error() as a bit noisier variant of printf().
This macro causes name conflict with the following line in
include/linux/compiler-gcc.h:# define __compiletime_error(message) __attribute__((error(message)))
This prevents us from using __compiletime_error(), and makes it
difficult to fully sync BUILD_BUG macros with Linux. (Notice
Linux's BUILD_BUG_ON_MSG is implemented by using compiletime_assert().)Let's convert error() into now treewide-available pr_err().
Done with the help of Coccinelle, excluing tools/ directory.

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).[1] https://cdimage.debian.org/cdimage/daily-builds/daily/arch-latest/arm64/iso-cd/

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.Signed-off-by: Maxime Ripard
