spl: stm32f7: configure for xip booting

2017-06-09T15:24:00Z

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. Signed-off-by: Vikas Manocha

stm32: stm32f7: add spl build support

2017-06-09T15:23:55Z

This commit supports booting from stm32 internal nor flash. spl U-Boot initializes the sdram memory, copies next image (e.g. standard U-Boot) to sdram & then jumps to entry point. Here are the flash memory addresses for U-Boot-spl & standard U-Boot: - spl U-Boot : 0x0800_0000 - standard U-Boot : 0x0800_8000 To compile u-boot without spl: Remove SUPPORT_SPL configuration (arch/arm/mach-stm32/Kconfig) Signed-off-by: Vikas Manocha [trini: Rework Kconfig logic a bit] Signed-off-by: Tom Rini

dm: gpio: Add live tree support

2017-06-01T13:03:10Z

Add support for requesting GPIOs with a live device tree. This involves adjusting the function signature for the legacy function gpio_request_by_name_nodev(), so fix up all callers. Signed-off-by: Simon Glass Fixes to stm32f746-disco.c: Signed-off-by: Tom Rini

dm: Use dm.h header when driver mode is used

2017-06-01T12:57:52Z

This header includes things that are needed to make driver build. Adjust existing users to include that always, even if other dm/ includes are present Signed-off-by: Simon Glass

stm32f746: to switch on user LED1 & read user button

2017-05-08T15:57:21Z

All discovery boards have one user button & one user LED. Here we are just reading the button status & switching ON the user LED. Signed-off-by: Vikas Manocha cc: Christophe KERELLO

stm32f7: use stm32f7 gpio driver supporting driver model

2017-05-08T15:57:21Z

With this gpio driver supporting DM, there is no need to enable clocks for different gpios (for pin muxing) in the board specific code. Need to increase the allocatable area required before relocation from 0x400 to 0xC00 becuase of 10 new gpio devices(& new gpio class) added in device tree.
