fa2f81b06f TI: Rework SRAM definitions and maximums
On all TI platforms the ROM defines a "downloaded image" area at or near
the start of SRAM which is followed by a reserved area.  As it is at
best bad form and at worst possibly harmful in corner cases to write in
this reserved area, we stop doing that by adding in the define
NON_SECURE_SRAM_IMG_END to say where the end of the downloaded image
area is and make SRAM_SCRATCH_SPACE_ADDR be one kilobyte before this.
At current we define the end of scratch space at 0x228 bytes past the
start of scratch space this this gives us a lot of room to grow.  As
these scratch uses are non-optional today, all targets are modified to
respect this boundary.

Tested on OMAP4 Pandaboard, OMAP3 Beagle xM

903f864302 configs: am4xhs: Modify SPL load address to fix UART boot issue
An issue in the TI secure image generation tool causes the ROM to
load the SPL at a different load address than what is specified by
CONFIG_ISW_ENTRY_ADDR while doing a peripheral boot on HS devices.

This causes the SPL to fail on secure devices during peripheral

The TI secure image generation tool has been fixed so that the SPL
will always be loaded at 0x403018E0 by the ROM code for both
peripheral and memory boot modes.

916224c38d tools: moveconfig: warn loudly if moved option has no entry in Kconfig
Currently, the tool gives up moving an option quietly if its entry
was not found in Kconfig.

If the option is not defined in the config header in the first
place, it is no problem (as the Kconfig entry may have been hidden
by reasonable "depends on").

However, if the option is defined in the config header, the missing
Kconfig entry is a sign of possible behavior change.  It is highly
recommended to manually check if the option has been moved as
expected.  In this case, let's add "suspicious" in the log and
change the log color (if --color option is given) to make it stand
out.

This was suggested by Tom in [1].

601147b06a serial: bcm283x_mu: Detect disabled serial device
On the raspberry pi, you can disable the serial port to gain dynamic frequency
scaling which can get handy at times.

However, in such a configuration the serial controller gets its rx queue filled
up with zero bytes which then happily get transmitted on to whoever calls
getc() today.

This patch adds detection logic for that case by checking whether the RX pin is
mapped to GPIO15 and disables the mini uart if it is not mapped properly.

That way we can leave the driver enabled in the tree and can determine during
runtime whether serial is usable or not, having a single binary that allows for
uart and non-uart operation.

warp7 can run different kernel versions, such as NXP 4.1 or mainline.

Currently the rootfs location is passed via mmcblk number and the
problem with this approach is that the mmcblk number for the eMMC
changes depending on the kernel version.

In order to avoid such issue, use UUID method to specify the rootfs
location.

Succesfully tested booting a NXP 4.1 and also a mainline kernel.

ab25f0f69f mx6ul_14x14_ev: Enable the CCGR clocks earlier
To be in the safe side we need to enable the CCGR clocks prior
to calling arch_cpu_init().

Inspired by Tim Harvey's commit d783c2744f ("imx: ventana: fix boot to SD").

7dbda25ecd mx6ul_14x14_evk: Pass refsel and refr fields to avoid hang
When running a NXP 4.1 kernel with U-Boot mainline on a mx6ul-evk,
we observe a hang when going into the lowest operational point of cpufreq.

This hang issue does not happen on the NXP U-Boot version.

After comparing the SPL DDR initialization against the DCD table
from NXP U-Boot, the key difference that causes the hang is the
MDREF register setting:

DATA 4 0x021B0020 0x00000800

,which means:

REF_SEL = 0 --> Periodic refresh cycle: 64kHz
REFR = 1 ---> Refresh Rate - 2 refreshes

So adjust the MDREF initialization for mx6ul_evk accordingly
to fix the kernel hang issue at low bus frequency.
