2017-06-09armv7m: Disable D-cache when booting nommu(ARMv7M) Linux kerneltnishinaga.dev@gmail.com
Disable D-Cache is required when booting nommu Linux kernel. (please see Linux kernel source "arch/arm/kernel/head-nommu.S") U-Boot is enabled D-cache and I-Cache at startup. However, it does not disable D-Cache before booting nommu Linux kernel. Therefore, I call dcache_disable() when the CPU is ARMv7M to fix this problem.

2017-06-09arm: omap: Unify get_device_type() functionSemen Protsenko
Refactor OMAP3/4/5 code so that we have only one get_device_type() function for all platforms. Details: - Add ctrl variable for AM33xx and OMAP3 platforms (like it's done for OMAP4/5), so we can obtain status register in common way - For now ctrl structure for AM33xx/OMAP3 contains only status register address - Run hw_data_init() in order to assign ctrl to proper structure - Remove DEVICE_MASK and DEVICE_GP definitions as they are not used (DEVICE_TYPE_MASK and GP_DEVICE are used instead) - Guard structs in omap_common.h with #ifdefs, because otherwise including omap_common.h on non-omap4/5 board files breaks compilation Buildman script was run for all OMAP boards. Result output: arm: (for 38/616 boards) all +352.5 bss -1.4 data +3.5 rodata +300.0 spl/u-boot-spl:all +284.7 spl/u-boot-spl:data +2.2 spl/u-boot-spl:rodata +252.0 spl/u-boot-spl:text +30.5 text +50.4 (no errors to report) Tested on AM57x EVM and BeagleBoard xM.

2017-06-09spl: stm32f7: configure for xip bootingVikas Manocha
With xip booting configuration, we don't need to copy the next image (U-Boot or linux xipimage) from flash to sdram area. Flash memory organization is like this: spl-U-Boot: u-boot-spl.bin : 0x0800_0000 U-Boot : u-boot-dtb.bin : 0x0800_8000 linux : xipImage : 0x0800_8000 It is also possible to have U-Boot binary & linux binaries configured at different addresses of flash memory like U-Boot at 0x0800_8000 & linux xipImage at 0x0800_4000. But in any case, spl-U-Boot needs to be compiled for U-Boot as next binary with SPL_OS_BOOT option disabled. By default, spl is configured to boot linux xipImage.

2017-06-07rockchip: video: rk3399: add HDMI TX support on the RK3399Philipp Tomsich
This commit enables the RK3399 HDMI TX, which is very similar to the one found on the RK3288. As requested by Simon, this splits the HDMI driver into a SOC-specific portion (rk3399_hdmi.c, rk3288_hdmi.c) and a common portion (rk_hdmi.c). Note that the I2C communication for reading the EDID works well with the default settings, but does not with the alternate settings used on the RK3288... this configuration aspect is reflected by the driverdata for the RK3399 driver. Having some sort of DTS-based configuration for the regulator dependencies would be nice for the future, but for now we simply use lists of regulator names (also via driverdata) that we probe.

2017-06-07rockchip: video: refactor rk_vop and split RK3288-specific code offPhilipp Tomsich
To prepare for adding the RK3399 VOP driver (which shares most of its registers and config logic with the RK3228 VOP), this change refactors the driver and splits the RK3288-specific driver off. The changes in detail are: - introduces a data-structure for chip-specific drivers to register features/callbacks with the common driver: at this time, this is limited to a callback for setting the pin polarities (between the VOP and the encoder modules) and a flag to signal 10bit RGB capability - refactors the probing of regulators into a helper function that can take a list of regulator names to probe and autoset - moves the priv data-structure into a (common) header file to be used by the chip-specific drivers to provide base addresses to the common driver - uses a callback into the chip-specific driver to set pin polarities (replacing the direct register accesses previously used) - splits enabling the output (towards an encoder) into a separate help function withint the common driver Signed-off-by: Philipp Tomsich <philipp.tomsich@theobroma-systems.com> Reviewed-by: Simon Glass <sjg@chromium.org>
