Increase default of CONFIG_SYS_MALLOC_F_LEN for SPL_OF_CONTROL

2016-09-07T12:48:58+00:00

If both SPL_DM and SPL_OF_CONTROL are enabled, SPL needs to bind
several devices, but CONFIG_SYS_MALLOC_F_LEN=0x400 is apparently
not enough.  Increase the default to 0x2000 for the case.  This
will be helpful for shorter defconfigs.

Kconfig: DISTRO_DEFAULTS: Only enable CMD_BOOTZ for ARM

2016-08-20T15:35:08+00:00

The 'bootz' command is really only for ARM32 Linux Kernel 'zImage' files
but has also been adapted for testing with sandbox.  Given that sandbox
is a test platform, don't add that logic under DISTRO_DEFAULTS.

cmd: booti: move CONFIG_CMD_BOOTI to Kconfig

2016-08-20T15:35:08+00:00

This command is used to boot ARM64 Linux.

I made DISTRO_DEFAULTS select this option for ARM64 to respect
include/config_distro_defaults.h.

common: image: Add support for post-processing of images

2016-08-12T13:22:18+00:00

This commit allows injecting a board/platform/device-specific post-
processing function into the FIT image data loading process, which can
include modifying the size and altering the starting source address of
an image data artifact. This might be desired to do things like strip
headers or footers attached to the images before they were packaged into
the FIT, or to perform operations such as decryption or authentication.
Introduce new configuration option CONFIG_FIT_IMAGE_POST_PROCESS to
allow controlling this feature. If enabled, a platform-specific post-
process function must be provided.

treewide: move CONFIG_PHYS_64BIT to Kconfig

2016-08-05T11:27:25+00:00

We need to ensure that CONFIG_PHYS_64BIT is configured via Kconfig so
that it is always available to the build system.  Otherwise we can run
into cases where we have inconsistent sizes of certain attributes.

Ravi Babu reported offset mismatch of struct dwc3 across files since
commit 95ebc253e6d4 ("types.h: move and redefine resource_size_t").
Since the commit, resource_addr_t points to phys_addr_t, whose size
is dependent on CONFIG_PHYS_64BIT for ARM architecture.

I tried my best to use "select" where possible (for example, ARMv8
architecture) because I think this kind of option is generally user-
unconfigurable.  However, I see some of PowerPC boards have 36BIT
defconfigs as well as 32BIT ones.  I moved CONFIG_PHYS_64BIT to the
defconfigs for such boards.

CONFIG_36BIT is no longer referenced, so all of the defines were
removed from CONFIG_SYS_EXTRA_OPTIONS.

libfdt: Introduce new ARCH_FIXUP_FDT option

2016-08-01T01:37:08+00:00

Add new Kconfig option to disable arch_fixup_fdt() calls for cases where
U-Boot shouldn't update memory setup in DTB file.
One example of usage of this option is to boot OS with different memory
setup than U-Boot use.

tools: Allow building with debug enabled

2016-07-14T22:22:31+00:00

Sometimes it is useful to build tools with debugging information included so
that line-number information is available when run under gdb. Add a Kconfig
option to support this.

spl: fit: add support for post-processing of images

2016-07-14T22:22:21+00:00

The next stage boot loader image and the selected FDT can be post-
processed by board/platform/device-specific code, which can include
modifying the size and altering the starting source address before
copying these binary blobs to their final destination. This might be
desired to do things like strip headers or footers attached to the
images before they were packaged into the FIT, or to perform operations
such as decryption or authentication. Introduce new configuration
option CONFIG_SPL_FIT_IMAGE_POST_PROCESS to allow controlling this
feature. If enabled, a platform-specific post-process function must

Kconfig: Add a new DISTRO_DEFAULTS Kconfig option

2016-06-21T01:30:13+00:00

DISTRO_DEFAULTS is intended to mirror / replace
include/config_distro_defaults.h.

The intend is for boards which include this file to select this from
their Kconfig files and when moving setting to Kconfig which are #define-ed
in config_distro_defaults.h to select this from DISTRO_DEFAULTS so that
boards which have selected DISTRO_DEFAULTS will keep the same configuration
as before without needing any defconfig file changes.

The initial list of selected things matches all settings recently removed
from config_distro_defaults.h because they have been converted to Kconfig,
with the exception of CMD_ELF and CMD_NET, which have a default of y, if
the default of these ever changes they should be selected by DISTRO_DEFAULTS
too.

For testing and example purposes this commit also converts ARCH_SUNXI
to use DISTRO_DEFAULT instead of selecting everything it needs itself.

verified-boot: Minimal support for booting U-Boot proper from SPL

2016-06-12T17:14:58+00:00

This allows a board to configure verified boot within the SPL using
a FIT or FIT with external data. It also allows the SPL to perform
signature verification without needing relocation.

The board configuration will need to add the following feature defines:
CONFIG_SPL_CRYPTO_SUPPORT
CONFIG_SPL_HASH_SUPPORT
CONFIG_SPL_SHA256

In this example, SHA256 is the only selected hashing algorithm.

And the following booleans:
CONFIG_SPL=y
CONFIG_SPL_DM=y
CONFIG_SPL_LOAD_FIT=y
CONFIG_SPL_FIT=y
CONFIG_SPL_OF_CONTROL=y
CONFIG_SPL_OF_LIBFDT=y
CONFIG_SPL_FIT_SIGNATURE=y
