efi_loader: avoid initializer element is not constant

2018-06-14T08:52:14+00:00

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.

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.

spl: disk: usb: Add dependencies to sprintf/strto*

2018-04-28T22:32:24+00:00

If SPL serial support is disabled nothing brings in sprintf, snprintf
or simple_strtoul:

  env/attr.c:128: undefined reference to `sprintf'
  disk/built-in.o: In function `blk_get_device_by_str':

  drivers/built-in.o: In function `init_peripheral_ep':

  drivers/built-in.o: In function `musb_core_init':

Add those dependencies here.

Remove unnecessary instances of DECLARE_GLOBAL_DATA_PTR

2018-04-27T18:54:48+00:00

We have a large number of places where while we historically referenced
gd in the code we no longer do, as well as cases where the code added
that line "just in case" during development and never dropped it.

part: Disable CONFIG_SPL_ISO_PARTITION by default

2018-04-16T22:45:35+00:00

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.

disk: part: scan the disk if the part_type is unknown

2018-03-14T01:46:05+00:00

If a DUT do not have partition table, and we write one with 'gpt write'
cmd, we should able to list the partition with 'part list' cmd.
It's reasonable to scan the disk again if the initial part_type is
unknown in case we just write a new one into disk.

Move most CONFIG_HAVE_BLOCK_DEVICE to Kconfig

2018-02-09T00:09:03+00:00

config_fallbacks.h has some logic that sets HAVE_BLOCK_DEVICE
based on a list of enabled options.  Moving HAVE_BLOCK_DEVICE to
Kconfig allows us to drastically shrink the logic in
config_fallbacks.h

config_fallback.h has some logic that checks a variety of options
