[PATCH] board: atmel: Fix compiler warning 'board_usb_hw_init()' not used
by Josef Lusticky 06 May '20

06 May '20

Wrap definition of board_usb_hw_init() around with #ifdef CONFIG_CMD_USB to avoid warning: 'board_usb_hw_init' defined but not used [-Wunused-function] when compiling without CONFIG_CMD_USB. This patch makes sama5d27_som1_ek, sama5d2_ptc_ek and sama5d2_xplained consistent with other boards that use the same #ifdef to avoid the warning.

[PATCH] board: sunxi: enable status LED in SPL
by Arnaud Ferraris 06 May '20

06 May '20

For some systems, such as the PinePhone, there is no way for the end user to make sure the system is indeed booting before the boot script is executed, which takes several seconds. Therefore, it can be useful to provide early visual feedback as soon as possible. In order achieve this goal, this patch initializes the status LED (if configured) in the SPL.

[PATCH v2 0/7] rockchip: make it possible to sign the u-boot.itb
by Heiko Stuebner 06 May '20

06 May '20

From: Heiko Stuebner <heiko.stuebner(a)theobroma-systems.com> This series fixes some issues I found with SPL_FIT_SIGNATURE enabled and then makes it possible to sign a generated u-boot.itb automatically even if the its-source got created by a generator script. To let the SPL know about the key, the -K option for mkimage points to the dts/dt-spl.dtb which can then get included into the spl binary. Tested on Rockchip PX30 with a TPL -> SPL -> U-Boot.itb bootchain. If the later parts are in doubt, maybe the first patches fixing obvious errors could land first separately. changes in v2: - add received reviews - fix commit message typo - add doc snippet explaining CONFIG_SPL_FIT_GENERATOR_KEY_HINT Heiko Stuebner (7): spl: fit: select SPL_HASH_SUPPORT for SPL_FIT_SIGNATURE spl: fit: select SPL_CRYPTO_SUPPORT for SPL_FIT_SIGNATURE lib: rsa: distinguish between tpl and spl for CONFIG_RSA_VERIFY mkimage: fit_image: handle multiple errors when writing signatures spl: fit: enable signing a generated u-boot.itb spl: fit: add Kconfig option to specify key-hint for fit_generator rockchip: make_fit_atf: add signature handling Kconfig | 18 +++++++++ Makefile | 11 +++++- arch/arm/mach-rockchip/make_fit_atf.py | 51 +++++++++++++++++++++++++- doc/uImage.FIT/howto.txt | 13 +++++++ lib/rsa/Makefile | 2 +- tools/image-host.c | 2 +- 6 files changed, 93 insertions(+), 4 deletions(-) -- 2.25.1
