8f079cccb3 armv7m: Disable D-cache when booting nommu(ARMv7M) Linux kernel
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.

00bbe96eba arm: omap: Unify get_device_type() function
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

264e420f36 davinci: omapl138_lcdk: fix tXSNR DDR2 timing value
As per the datasheet[1] available for DDR2 part on board
the OMAP-L138 LCDK, the tXSNR (exit self refresh to a
non-read command) is 137.5 ns. This corresponds to a
value of 20 to be written to T_XSNR register field of
OMAP-L138's DDR configuration. The DDR2 is at 150 MHz.

Fix this. The correct value also appears on the initialization
scripts (called CCS GEL files) available on TI's wiki pages[2]

1a73bd842e spl: stm32f7: configure for xip booting
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.

64199d4ead rockchip: video: rk_vop: add grf field
The last set of rebases had dropped the 'grf' field from the common
rk_vop.  Add this back to un-break the build (and driver).

ca562b630e rockchip: video: rk3399: add HDMI TX support on the RK3399
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.

147fd3ac5a rockchip: video: split RK3288-specific part off from rk_hdmi
To prepare for the addition of RK3399 HDMI support, the HDMI driver is
refactored and broken into a chip-specific and a generic part.  This
change adds the internal interfaces, makes common/reusable functions
externally visible and splits the RK3288 driver into a separate file.

For the probing of regulators, we reuse the infrastructure created
during the VOP refactoring... i.e. we simply call into the helper
function defined for the VOP.
