2018-11-28pinctrl: MediaTek: add pinctrl driver for MT7629 SoCRyder Lee
This patch adds pinctrl support for MT7629 SoC. The IO core found on the SoC has the registers for pinctrl, pinconf and gpio mixed up in the same register range. Hence the driver also implements the gpio functionality through UCLASS_GPIO. This also creates a common file as there might be other chips that use the same binding and driver, then being a little more abstract could help in the long run.

2018-11-26armv7r: K3: Allow SPL to run only on core 0Lokesh Vutla
Based on the MCU R5 efuse settings, R5F cores in MCU domain either work in split mode or in lock step mode. If efuse settings are in lockstep mode: ROM release R5 cores and SPL continues to run on the R5 core is lockstep mode. If efuse settings are in split mode: ROM releases both the R5 cores simultaneously and allow SPL to run on both the cores. In this case it is bootloader's responsibility to detect core 1 and park it. Else both the core will be running bootloader independently which might result in an unexpected behaviour. Signed-off-by: Lokesh Vutla <lokeshvutla@ti.com> Reviewed-by: Tom Rini <trini@konsulko.com>

2018-11-26ARM: meson: Add boot device discoveryNeil Armstrong
The Amlogic Meson SoCs ROM supports a boot over USB with a custom protocol. When no other boot medium are available (or by forcing the USB mode), the ROM sets the primary USB port as device mode and waits for a Host to enumerate. When enumerated, a custom protocol described at [1] permits writing to memory and execute some specific FIP init code to run the loaded Arm Trusted Firmware BL2 and BL3 stages before running the BL33 stage. In this mode, we can load different binaries that can be used by U-boot like a script image file. This adds support for a custom USB boot stage only available when the boot mode is USB and the script file at a pre-defined address is valid. This support was heavily copied from the Sunxi Allwinner FEL U-Boot support. The tool pyamlboot described at [2], permits using this boot mode on boards exposing the first USB port, either as OTG or Host port.

2018-11-26sandbox: Boot in U-Boot through the standard callSimon Glass
Most architectures use jump_to_image_no_args() to jump from SPL to U-Boot. At present sandbox is special in that it jumps in its spl_board_load_image() call. This is not strictly correct, and means that sandbox misses out some parts of board_init_r(), just as calling bloblist_finish(), for example. Change spl_board_load_image() to just identify the filename to boot, and implement jump_to_image_no_args() to actually jump to it. Signed-off-by: Simon Glass <sjg@chromium.org>
2018-11-26sandbox: Filter arguments when starting U-BootSimon Glass
The current method of starting U-Boot from U-Boot adds arguments to pass the memory file through, so that memory is preserved. This is fine for a single call, but if we call from TPL -> SPL -> U-Boot the arguments build up and we have several memory files in the argument list. Adjust the implementation to filter out arguments that we want to replace with new ones. Also print a useful error if the exec() call fails. Signed-off-by: Simon Glass <sjg@chromium.org>
2018-11-26sandbox: Use malloc() and free() from os layerSimon Glass
At present sandbox calls malloc() from various places in the OS layer and this results in calls to U-Boot's malloc() implementation. It is better to use the on in the OS layer, since it does not mix allocations with the main U-Boot code. Fix this by replacing calls with malloc() to os_malloc(), etc. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Joe Hershberger <joe.hershberger@ni.com>
