dm: core: Create a new header file for 'compat' features

2020-02-06T02:33:46+00:00

At present dm/device.h includes the linux-compatible features. This
requires including linux/compat.h which in turn includes a lot of headers.
One of these is malloc.h which we thus end up including in every file in
U-Boot. Apart from the inefficiency of this, it is problematic for sandbox
which needs to use the system malloc() in some files.

Move the compatibility features into a separate header file.

dm: core: Require users of devres to include the header

2020-02-06T02:33:46+00:00

At present devres.h is included in all files that include dm.h but few
make use of it. Also this pulls in linux/compat which adds several more
headers. Drop the automatic inclusion and require files to include devres
themselves. This provides a good indication of which files use devres.

string: Allow arch override of strndup() also

At present architectures can override strdup() but not strndup(). Use
the same option for both.

libfdt: Revert 6dcb8ba4 from upstream libfdt

2020-01-30T18:30:35+00:00

In upstream libfdt, 6dcb8ba4 "libfdt: Add helpers for accessing
unaligned words" introduced changes to support unaligned reads for ARM
platforms and 11738cf01f15 "libfdt: Don't use memcpy to handle unaligned
reads on ARM" improved the performance of these helpers.

In practice however, this only occurs when the user has forced the
device tree to be placed in memory in a non-aligned way, which in turn
violates both our rules and the Linux Kernel rules for how things must
reside in memory to function.

This "in practice" part is important as handling these other cases adds
visible (1 second or more) delay to boot in what would be considered the
fast path of the code.

optee: Replace uninitialized return variable by proper one.

2020-01-30T18:30:35+00:00

As hinted by GCC 9, there is a return statement that returns
an uninitialized variable in optee_copy_firmware_node().
This patch addresses this.

lib: Kconfig dependencies for pseudo-random library

2020-01-25T17:04:36+00:00

drivers/rng/sandbox_rng.c requires rand() to be defined but configuration
option CONFIG_CONFIG_LIB_RAND selected in drivers/rng/Kconfig does not
exist.

test/lib/test_aes.c requires rand() to be defined.

Fix the selection criteria for choice "Pseudo-random library support type".

lib: rsa: consider CONFIG_SPL_RSA

2020-01-25T17:04:36+00:00

CONFIG_SPL_RSA is meant to control if lib/rsa/* is used for SPL. Adjust
lib/Makefile to consider this setting.

This was correctly setup with commit 51c14cd128f4 ("verified-boot: Minimal
support for booting U-Boot proper from SPL") and got lost with commit
089df18bfe9d ("lib: move hash CONFIG options to Kconfig").
