f2863ff3f4 arm: imx: make bmode command work with SPL/U-Boot combo
The bmode command forces the SoC to use a specific boot device
by writing its boot mode into SRC_GPR9, and notifying the SoC of
the change using SRC_GPR10[28] bit: if the bit is on, bootROM
uses the value in SRC_GPR9 instead of SRC_SMBR1 to determine
the boot device.

SPL on the other hand is oblivious to this distinction, so once
the bootROM loads SPL from the device configured in SRC_GPR10,
SPL will attempt to load U-Boot from the device configured in
SRC_SMBR1, which is not updated by the bootROM to the value in
SRC_GPR9.

The result is that the selected boot device is not used across all
the boot stages.

Update spl_boot_device() to look at gpr9 when necessary.

8fe280f330 imx: mx6 sabreauto: Add board support for USB EHCI
On mx6 sabreauto board, there are two USB ports:
0: OTG
1: HOST
The EHCI driver is enabled for this board, but the IOMUX and VBUS power
control is not implemented, which cause both USB port failed to work.
This patch fix the problem by adding the board support codes.

Since the power control uses the GPIO pin from port expander MAX7310,
the PCA953X driver is enabled for accessing the MAX7310.

The ID pin of OTG Port needs to configure the GPR1 bit 13 for selecting
its daisy chain. Add a new function "imx_iomux_set_gpr_register" to
handle GPR register setting.

1a1f795078 imx: gpt: Add High frequency clock source support for GPT
Introduce a new configuration "CONFIG_MXC_GPT_HCLK". When it is set,
the GPT will select a high frequency clock as clock source.
Otherwise, the GPT will stay to use 32Khz OSC as clock source.

In the implementation, since only the GPT on i.MX6 series provide the
clock source option for 24Mhz OSC. For others (only i.MX5 and i.MX6
compile the driver), if the configuration is set, the perclk will be
selected as clock source.
MX6Q/D Rev 1.0 and MX6SL are special in the implementation, because they
don't have the 24Mhz OSC clock source option, so also select the perclk
for them. For MX6SL, we will set the OSC 24Mhz to perclk in CCM, so
eventually the clock comes from OSC 24Mhz.

fcfdfdd58c ARM: mx6: Prevent overflow in DRAM size detection
The MX6 DRAM controller can be configured to handle 4GiB of DRAM, but
only 3840 MiB of that can be really used. In case the controller is
configured to operate a 4GiB module, the imx_ddr_size() function will
correctly compute that there is 4GiB of DRAM in the system. Firstly,
the return value is 32-bit, so the function will effectively return
zero. Secondly, the MX6 cannot address the full 4GiB, but only 3840MiB
of all that. Thus, clamp the returned size to 3840MiB in such case.

0a11d6f29c mx6: Remove duplication of iomuxc structure
There is no need to keep iomuxc_base_regs structure as it serves the exact same
purpose of the iomuxc structure, which is to provide access to the GPR
registers.

The additional fields of iomuxc_base_regs are not used. Other advantage of
'iomuxc' is that it has a shorter name and the variable declarations can fit
into a single line.

So remove iomuxc_base_regs structure and use iomuxc instead.

6825a95b0b kbuild: use Linux Kernel build scripts
Now we are ready to switch over to real Kbuild.

This commit disables temporary scripts:
  scripts/{Makefile.build.tmp, Makefile.host.tmp}
and enables real Kbuild scripts:
  scripts/{Makefile.build,Makefile.host,Makefile.lib}.

This switch is triggered by the line in scripts/Kbuild.include
  -build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build.tmp obj
  +build := -f $(if $(KBUILD_SRC),$(srctree)/)scripts/Makefile.build obj

We need to adjust some build scripts for U-Boot.
But smaller amount of modification is preferable.

Additionally, we need to fix compiler flags which are
locally added or removed.

In Kbuild, it is not allowed to change CFLAGS locally.
Instead, ccflags-y, asflags-y, cppflags-y,
CFLAGS_$(basetarget).o, CFLAGS_REMOVE_$(basetarget).o
are prepared for that purpose.

10f779da54 imx: nitrogen6x: mx6qsabrelite: Add support for DVI monitors
A little background is probably appropriate for this patch.

Since "the beginning" of usage of the SABRE Lite and Nitrogen6x
boards, DVI detection has been somewhat broken.

Some (most) DVI monitors don't produce the "HPD" bit in
the PHY_STAT0 register, but do show proper toggling of the
RX_SENSE0..3 bits.

Creating a new the bit-mask to include all five bits and
modifying the 'hdmidet' command and internal detection
routines allows these monitors to function properly in U-Boot.

A related patch to our kernels allows things to work under
Linux:
