u-boot.git/common/image-fdt.c, branch master

Create a new boot/ directory

2021-11-12T00:01:56+00:00

Quite a lot of the code in common/relates to booting and images. Before
adding more it seems like a good time to move the code into its own
directory.

Most files with 'boot' or 'image' in them are moved, except:

- autoboot.c which relates to U-Boot automatically running a script
- bootstage.c which relates to U-Boot timing

Drop the removal of boot* files from the output directory, since this
interfers with the symlinks created by tools and there does not appear
to be any such file from my brief testing.

image: Split up boot_get_fdt()

2021-10-08T19:53:27+00:00

This function is far too long. Before trying to remove #ifdefs, split out
the code that deals with selecting the FDT into a separate function.

image: Reduce variable scope in boot_get_fdt()

2021-10-08T19:53:27+00:00

Move the variables declarations to where they are needed, to reduce the
number of #ifdefs needed.

2021-10-08T19:53:26+00:00

This is not needed with Kconfig, since we can use IS_ENABLED() easily
enough. Drop it.

ti: keystone: Move away from CONFIG_SOC_KEYSTONE

2021-09-28T01:38:34+00:00

We have individual SOC symbols for each keystone 2 platform.  Use the
existing CONFIG_ARCH_KEYSTONE rather than CONFIG_SOC_KEYSTONE to
encompass all of the keystone families.

global: Convert simple_strtoul() with hex to hextoul()

2021-08-02T17:32:14+00:00

It is a pain to have to specify the value 16 in each call. Add a new
hextoul() function and update the code to use it.

Add a proper comment to simple_strtoul() while we are here.

image-fdt: save no-map parameter of reserve-memory

2021-06-07T14:48:40+00:00

Save the 'no-map' information present in 'reserved-memory' node to allow
correct handling when the MMU is configured in board to avoid
speculative access.

This binding is defined in
doc/device-tree-bindings/reserved-memory/reserved-memory.txt

Additional properties:
...
no-map (optional) - empty property
    - Indicates the operating system must not create a virtual mapping
      of the region as part of its standard mapping of system memory,
      nor permit speculative access to it under any circumstances other
      than under the control of the device driver using the region.

lib: optee: migration optee_copy_fdt_nodes for OF_LIVE support

2021-04-12T18:25:31+00:00

The optee_copy_fdt_nodes is only used to copy op-tee nodes
of U-Boot device tree (from gd->fdt_blob when OF_LIVE is not activated)
to external device tree but it is not compatible with OF_LIVE.

This patch migrates all used function fdt_ functions to read node on
old_blob to ofnode functions, compatible with OF_LIVE and remove this
parameter "old_blob".

The generated "device tree" is checked on stm32mp platform with OF_LIVE
activated.

cmd: fdt: skip board specific fixup using env variable

2021-02-24T21:51:48+00:00

Sometimes it is useful to boot OS with already fixed-up
device tree. Check for env variable 'skip_board_fixup'
before calling ft_board_setup().
Current behaviour is unchanged, additionally user can
set skip_board_fixup to 1 to skip the fixup.
