[U-Boot] [PATCH] ARM: at91: Don't invoke spl_boot_device() twice
by Marek Vasut 26 Jun '16

26 Jun '16

Since the spl_boot_mode() is now passed the boot device to boot from, make use of it instead of inquiring for the boot device again. This allows board_boot_order() to function correctly.

[U-Boot] [PATCH] common: Pass the boot device into spl_boot_mode()
by Marek Vasut 26 Jun '16

26 Jun '16

The SPL code already knows which boot device it calls the spl_boot_mode() on, so pass that information into the function. This allows the code of spl_boot_mode() avoid invokind spl_boot_device() again, but it also lets board_boot_order() correctly alter the behavior of the boot process. The later one is important, since in certain cases, it is desired that spl_boot_device() return value be overriden using board_boot_order().

[U-Boot] [PATCH v2 0/9] Secure Boot by Authenticating/Decrypting SPL FIT blobs
by Andreas Dannenberg 26 Jun '16

26 Jun '16

This is an updated version of a patch series that introduces a generic way to optionally post-process blobs as they get extracted by the SPL from the u-boot.img FIT image, and uses this scheme to perform some authentication/ decryption related processing on TI's high-secure (HS) SoC variants. For additional background please see here [1]. Despite there being a few changes (see below) based on previous feedback (thanks!) I did carry forward most of the Reviewed-by: tags as I felt the fundamental approach and most if not all of the building blocks pretty much stayed intact, I hope that's okay. I've also completely re-rested the series on all applicable HS devices and checked for any build issues as well as runtime issues without findings. Changes PATCH->PATCH v2: - Added some glue code to suppress SPL "Authentication passed" log messages in case of UART/Y-Modem boot (thanks Lokesh) - Dropped the .NOTPARALLEL make hack when building the 'dtbs' target. Now, we rely on Yamada-san's patch [2] that fixes this on a more global scale - Fixed some typos (thanks Yamada-san) - Turned the __weak function call for inserting a post-processing function into a Kconfig option (thanks Simon). Also enabled that Kconfig option on applicable AM43xx HS, AM57xx HS, DRA7xx HS, and DRA72xx HS device variants defconfig files (note there is a dependency on [3] which renames the AM437x HS defconfig file) - Introduced a new header file omap_sec_common.h for commom security API as using omap_common.h as done previously led to issues trying to use this file on AM43xx type devices. This device family (and AM335x as well) is not supported by omap_common.h, and trying to include this file into AM43xx board files leads to all kinds of issues (the registers and definitions are simply not compatible) - Re-ordered the series so that the Kconfig option is introduced after all of the building blocks have been put into place (generic infrastructure and the TI-specific implementation). - Minor readme update to account for the new Kconfig option Changes RFC->PATCH: - Update of README.ti-secure - Unification of some of the secure ROM API call stuff between AM43xx and OMAP5-based platforms by moving those into common files - Replacement of puts() with printf() - Minor build simplification/cleanup - Addition of "Reviewed-by:" comments for files that were pretty much carried over from the RFC as-is - Addition of AM437x HS device build support (was missing in RFC) - Removal of some redundant conditional compile directives - Rebased on upstream U-Boot commit "Prepare v2016.07-rc2" -- Andreas Dannenberg Texas Instruments Inc [1] http://lists.denx.de/pipermail/u-boot/2016-June/258716.html [2] http://lists.denx.de/pipermail/u-boot/2016-June/258912.html [3] http://lists.denx.de/pipermail/u-boot/2016-June/258896.html Andreas Dannenberg (5): arm: omap-common: add secure rom call API for secure devices arm: omap-common: secure ROM signature verify API arm: omap-common: Update to generate secure U-Boot FIT blob arm: omap5: add U-Boot FIT signing and SPL image post-processing doc: Update info on using secure devices from TI Daniel Allred (3): arm: cache: add missing dummy functions for when dcache disabled arm: omap-common: add secure smc entry spl: fit: add support for post-processing of images Madan Srinivas (1): arm: am4x: add U-Boot FIT signing and SPL image post-processing Kconfig | 4 + arch/arm/cpu/armv7/am33xx/config.mk | 1 + arch/arm/cpu/armv7/cache_v7.c | 8 ++ arch/arm/cpu/armv7/omap-common/Makefile | 2 + arch/arm/cpu/armv7/omap-common/config_secure.mk | 75 ++++++++-- arch/arm/cpu/armv7/omap-common/lowlevel_init.S | 45 ++++-- arch/arm/cpu/armv7/omap-common/sec-common.c | 138 ++++++++++++++++++ arch/arm/cpu/armv7/omap5/config.mk | 3 + arch/arm/include/asm/omap_common.h | 6 + arch/arm/include/asm/omap_sec_common.h | 30 ++++ board/ti/am43xx/board.c | 8 ++ board/ti/am57xx/board.c | 8 ++ board/ti/dra7xx/evm.c | 9 ++ common/spl/spl_fit.c | 21 ++- configs/am43xx_hs_evm_defconfig | 1 + configs/am57xx_hs_evm_defconfig | 1 + configs/dra7xx_hs_evm_defconfig | 1 + doc/README.ti-secure | 177 ++++++++++++++++-------- include/image.h | 17 +++ 19 files changed, 473 insertions(+), 82 deletions(-) create mode 100644 arch/arm/cpu/armv7/omap-common/sec-common.c create mode 100644 arch/arm/include/asm/omap_sec_common.h -- 2.6.4

[U-Boot] [PATCH v2 00/55] RFC: dm: rockchip: Add support for compiled-in platform data
by Simon Glass 26 Jun '16

26 Jun '16

Note: This v2 series has some minor updates and improvements, mostly as new patches in the series. This series provides a way to compile in the contents of a device tree as C code into U-Boot, implementing an idea that Tom Rini came up with. It is intended to deal with extremely tight environments where there is not enough space for the ~3KB device tree code overhead. Examples include SPL where there is only 16KB of available RAM yet a full MMC stack is required. To provide a reasonable test environment, SPL support is added to sandbox, through a new 'sandbox_spl' target. A new tool 'dtoc' converts device tree data to C code (and structure definitions). To check its effectiveness for a real application, the v2 series includes support for enabling of-platdata for a rockchip board (firefly-rk3288). The results are as follows: Code Data u-boot-spl.bin size of-platdata disabled 23159 1624 28864 of-platdata enabled 19093 2616 21761 Overall the saving is 7103 bytes, about 7KB. Approximately 4KB of this comes from removing the device tree data from SPL although this is offset by the size of the of-platdata itself (around 1KB). On top of this effective 3KB reduction, another ~3KB reduction comes from dropping libfdt and a further 1KB from dropping unused setup and driver-model code. Clearly this approach does have value. Looked at with a favourable light it provides the best of both worlds: configuration using standard device tree bindings without the run-time overhead. Looking under the hood shows a less rosy picture. Effectively we end up with a new set of C structures which must be handled by the driver. This series suggests a suitable approach for dealing with this (see of-plat.txt) which is workable. However there are a number of serious caveats. See that file for details. If this feature makes it to mainline it should be used sparingly. Rockchip is to some extent an unusual case: lots of features, no MMC stack available to SPL from the internal ROM* and a very limited maximum SPL size. Most SoCs will not benefit from this. However, for an SoC with very small SRAM where only a few drivers are needed in SPL (such as serial and MMC) then of-platdata could provide a useful benefit, without a significant increase in complexity. More work is needed before this feature is ready for use, but this series contains enough to attract initial comments and testing. It is available at u-boot-dm/dt-working. * Note that the rockchip internal ROM does include an MMC stack but it only permits loading of data in its own format, outside control of U-Boot.

[U-Boot] [PATCH 1/3] tools: patman: Handle tag sections without an 'END'
by Bin Meng 26 Jun '16

26 Jun '16

'Cover-letter', 'Series-notes' and 'Commit-notes' tags require an 'END' to be put at the end of its section. When 'END' is missing, patman generates incorrect patches. This adds codes to handle such scenario.

[U-Boot] U-Boot SPL/Falcon mode Support on Minnowboard Max
by vinoth eswaran 26 Jun '16

26 Jun '16

Hello, I have gone through the document in U-boot Readme.falcon in which it explains we can skip loading the u-boot and load the Linux kernel directly. This will save time for systems that looks to optimize the start up time. In the document its mentioned that the "spl_start_uboot()" - as the required function to be implemented as board specific to support this functionality. I have checked the code and found no such function is defined for x86. Does that mean that Falcon mode is not supported in x86 arhitectures?? Mit Freundlichen Grüßen VinothKumar +49 1798909072

[U-Boot] [PATCH v5 0/5] ARM: AT91: Add AT91 PIO4 pinctrl driver and gpio driver with DM
by Wenyou Yang 26 Jun '16

26 Jun '16

AT91 PIO4 controller is a combined gpio-controller, pin-mux and pin-config module. This patch is to add the pinctrl driver, and rework the atmel-pio4 gpio driver to support driver model and device tree. Changes in v5: - Update the clk API based on [PATCH] clk: convert API to match reset/mailbox fstyle (http://patchwork.ozlabs.org/patch/625342/). - Use clrbits_le32() to replace readl()/writel(). - Fixed the return value, -ENODEV->-EINVAL. - Remove check on dev_get_parent() return. - Fixed the return value, -ENODEV->-EINVAL. - Remove check on dev_get_parent() return. - Collect Reviewed-by tags. Changes in v4: - Remove the redundant log print. Changes in v3: - Add bind callback to support the pinctl device regarding as a child of atmel_pio4 device. - Add clock support. - Rework due to the pinctrl device is regarded as atmel_pio4 device's child. Changes in v2: - remove meaningless comment. - add else path for argument of pinconf. - add inline attribute for atmel_pio4_bank_base(). - add handle if the pinmux entries is greater maximum value. - add detailed example to show how to configure pinctrl for device. - remove interrupt and gpio property description. - add reviewed-by tag. - integrate the gpio rework patch into this patch series. - add the new patch to move the PIO4 definitions to head file and rephrase them. - add the new patch to add #ifndef before CONFIG_ATMEL_PIO4 in configs/sama5d2_xplained.h Wenyou Yang (5): gpio: atmel_pio4: Move PIO4 definitions to head file gpio: atmel_pio4: Rework to support DM & DT pinctrl: at91-pio4: Add pinctrl driver atmel: Bring in at91 pio4 device tree file and bindings configs: sama5d2_xplained: Add #ifndef before CONFIG_ATMEL_PIO4 arch/arm/dts/sama5d2-pinfunc.h | 880 +++++++++++++++++++++ arch/arm/mach-at91/include/mach/atmel_pio4.h | 35 + .../pinctrl/atmel,at91-pio4-pinctrl.txt | 66 ++ drivers/gpio/Kconfig | 2 +- drivers/gpio/atmel_pio4.c | 201 +++-- drivers/pinctrl/Kconfig | 7 + drivers/pinctrl/Makefile | 1 + drivers/pinctrl/pinctrl-at91-pio4.c | 182 +++++ include/configs/sama5d2_xplained.h | 2 + 9 files changed, 1304 insertions(+), 72 deletions(-) create mode 100644 arch/arm/dts/sama5d2-pinfunc.h create mode 100644 doc/device-tree-bindings/pinctrl/atmel,at91-pio4-pinctrl.txt create mode 100644 drivers/pinctrl/pinctrl-at91-pio4.c -- 2.7.4
