when CLKM is running. If we stop CLKM when sampling it the glitches
all go away, so we'll do that as per Samsung suggestion.
We also check the "is it locked" bits of PHY_CON13 and loop until they
show the the value sampled actually represents a locked value. It
doesn't appear that the glitching and "is it locked" are related, but
it seems wise to wait until the PHY tells us the value is good before
we use it. In practice we will not loop more than a couple times (and
usually won't loop at all).

This patch intends to remove all code which enables hardware read
leveling. All characterization environments may not cope up with
h/w read leveling enabled, so we must disable this.
Also, disabling h/w read leveling improves the MIF LVcc value
(LVcc value is the value at which DDR will fail to work properly).
Improving LVcc means we have enough voltage margin for MIF.
When h/w leveling is enabled, we have almost zero volatge margin.

During bootm/z, U-Boot relocates the DTB and initrd to high memory so
they are out of the way of the kernel. On ARM at least, some parts of
high memory are "highmem" and can't be accessed at early boot. To solve
this, we need to restrict this relocation process to use lower parts of
RAM that area accessible.
For the DTB, an earlier patch of mine set CONFIG_SYS_BOOTMAPSZ. However,
since some platforms have different restrictions on DTB and initrd
location, that config option doesn't affect the initrd. We need to set
the initrd_high environment variable to control the initrd relocation.
Since we have carefully chosen the load addresses for the DTB and
initrd (see comments in include/configs/tegraNNN-common.h re: values in
MEM_LAYOUT_ENV_SETTINGS), we don't actually need any DTB or initrd
relocation at all. Skipping relocation removes some redundant work.
Hence, set both fdt_high and initrd_high to ffffffff which completely
disables relocation.
If the user does something unusual, such as using custom locations for
the DTB/initrd load address or wanting to use DTB/initrd relocation for
some reason, they can simply set these variables to custom values to
override these environment defaults.
With this change, cmd_sysboot works correctly for a filesystem created
by the Fedora installer.

extlinux.conf is stored in /boot/extlinux/extlinux.conf rather than
/boot/extlinux.conf. Adjust Tegra's default boot scripts to use the
correct location. This change aligns Tegra's boot scripts with rpi_b.h
and also the location that the Fedora installer actually puts the file.

The calling code seems a bit in doubt about the return

The u-boot Overo board actually supports both Overo (OMAP35xx)
and Overo Storm (AM/DM37xx) COMs with a range of different expansion
boards. This provides a mechanism to select the an appropriate device
tree file based on the processor version and, if available, the
expansion board ID written on the expansion board EEPROM. To match the
3.15+ kernels, fdtfile names have this format:
"omap3-overo[-storm]-<expansion board name>.dtb"
By default, we use "omap3-overo-storm-tobi.dtb".

gpmc timeout is disabled and the reset counter
is set to 0. However, if later a driver activates
the timeout setting the reset to a valid value,
the old reset value with zero is still valid
for the first access. In fact, the timeout block
loads the reset counter after a successful access.
Found on a am335x board with a FPGA connected
to the GPMC bus together with the NAND.
When the FPGA driver in kernel activates
the timeout, the system hangs at the first access
by the NAND driver.

Commit e9fd66defd7e (ARM: mx6: define CONFIG_ARM_ERRATA_742230) enables
errata 742230 for imx6, because it helps remove one reboot issue.
However, this errata does not really apply on imx6, because Cortex-A9
on imx6 is r2p10 while the errata only applies to revisions r1p0..r2p2.
At a later time, commit f71cbfe3ca5d (ARM: Add workaround for Cortex-A9
errata 794072) adds support of errata 794072, which applies to all
Cortex-A9 revisions. As the workaround for both errata are exactly
same, it makes a lot more sense to select 794072 instead of 742230 for
imx6. Since we already enable 794072 for imx6, it's time to drop
errata 742230 to avoid confusion.

Switch to an SPL image. The SPL for Ventana does the following:
- setup i2c and read the factory programmed EEPROM to obtain DRAM config
and model for board-specific calibration data
- configure DRAM per CPU/size/layout/devices/calibration
- load u-boot.img from NAND and jump to it
This allows for a single SPL+u-boot.img to replace the previous multiple boa
configurations.

Add memory-mapped structures for MMDC iomux and configuration. Note that whi
the MMDC configuration registers are common between the IMX6DQ
(IMX6DUAL/IMX6QUAD) and IMX6SDL (IMX6SOLO/IMX6DUALLITE) types the iomux
registers differ. This requires two sets of structures.
Add structures to describe DDR3 device information, system information
(memory layout, etc), and MMDC calibration registers that can be used to
configure the MMDC dynamically.
We define these structures for SPL builds instead of including mx6q-ddr.h an
mx6dl-ddr.h which use the same namespace and are only useful for imximage cf
files.

Add a common spl.c file to support boot device functions needed for SPL
such as detecting the boot device.

This utilizes existing mxs_nand support layer to provide a method to load an
image off nand for SPL. The flash device will be detected in order to support
multiple flash devices instead of having layout hard coded at build time.

arch/arm/include/asm/spl.h requires all SoCs to have
arch/arm/include/asm/arch-*/spl.h.
But many of them just define BOOT_DEVICE_* macros.
Those macros are used in the "switch (boot_device) { ... }"
statement in common/spl/spl.c.
So they should not be archtecture specific, but be described as
a simpile enumeration.
This commit merges most of arch/arm/include/asm/arch-*/spl.h
into arch/arm/include/asm/spl.h.
With a little more effort, arch-zynq/spl.h and arch-socfpga/spl.h
will be merged, while I am not sure about OMAP and Exynos.
