eba6589f7e board: Add uCRobotics Bubblegum-96 board support
This commit adds uCRobotics Bubblegum-96 board support. This board is
one of the 96Boards Consumer Edition platform based on Actions Semi
S900 SoC.

Features:
- Actions Semi S900 SoC (4xCortex A53, Power VR G6230 GPU)
- 2GiB RAM
- 8GiB eMMC, uSD slot
- WiFi, Bluetooth and GPS module
- 2x Host, 1x Device USB port
- HDMI
- 20-pin low speed and 40-pin high speed expanders, 6 LED, 3 buttons

U-Boot will be loaded by ATF at EL2 execution level. Relevant driver
support will be added in further commits.

c2ca3fdfb9 ARM: Introduce ability to enable invalidate of BTB with ICIALLU on Cortex-A15 for CVE-2017-5715
As recommended by Arm in [1], ACTLR[0] (Enable invalidates of BTB)
needs to be set[2] for BTB to be invalidated on ICIALLU. This needs to
be done unconditionally for Cortex-A15 processors. Provide a config
option for platforms to enable this option based on impact analysis
for products.

NOTE: This patch in itself is NOT the final solution, this requires:
a) Implementation of v7_arch_cp15_set_acr on SoCs which may not
   provide direct access to ACR register.
b) Operating Systems such as Linux to provide adequate workaround in the
   right locations.
c) This workaround applies to only the boot processor. It is important
   to apply workaround as necessary (context-save-restore) around low
   power context loss OR additional processors as necessary in either
   firmware support OR elsewhere in OS.

This patch is adding minimal support to get U-Boot boot.

Except for MPU(Memory Protection Unit) and few CP15 registers, most of the
features are compatible with v7 architecture. So,reuse the same armv7
folder and introduce a new config CPU_V7R in order to differentiate
from v7 based platforms.

acf1500138 arm: v7: Kconfig: Rename CPU_V7 as CPU_V7A
Currently CPU_V7 kconfig symbol supports only ARMv7A architectures under
armv7 folder. This led to a misconception of creating separate folders
for armv7m and armv7r. There is no reason to create separate folder for
other armv7 based architectures when it can co-exist with few Kconfig
symbols.

As a first step towards a common folder, rename CPU_V7 as CPUV7A. Later
separate Kconfig symbols can be added for CPU_V7R and CPU_V7M and
can co exist in the same folder.

directly inside of the serial driver.  First, introduce a new symbol to
guard the use of CONFIG_CONS_INDEX, so that in the case where we don't
need this for the serial driver, but for some other use, we can still do
it.  Next, consolidate all of these into the single entry in
drivers/serial/Kconfig.  Finally, introduce CONS_INDEX_[023456] so that
we can imply a correct value here to make the defconfig side of this
smaller.

5fbed8f2c6 ARM: Kconfig: Move TI_SECURE_DEVICE to a common area
TI_SECURE_DEVICE is used by both OMAP2+ and Keystone2 family devices,
and so when ARCH_OMAP2PLUS was used to gate off the OMAP2+ Kconfig
Keystone2 family devices lost this config option.

Move this option out of mach-omap2 Kconfig to a spot accessible by both
families. We picked arch/arm/Kconfig over the TI specific board/ti/
location as this option is not specific to our boards but rather our
architecture.

Plus at some point this option can be changed to just
SECURE_DEVICE, as having secure parts is not exclusive to TI and
so other vendors can interpret this option as needed by their device
configurations.

The motivation for moving MX23 selection to Kconfig is to be able
to better handle NAND MXS selection through Kconfig.

This selection method also aligns with the way other i.MX SoCs are
selected in U-Boot.

93561a327b arm: zynq: Enable DM_GPIO when needed
There are two reasons for doing this change.
There is still !DM driver for xilinx soft gpio IP and especially it is
saving some space for memory constrained boards like cse (almost ~400B).

Do not enable DM_ETH/MMC if subsystems are not enabled.
This saves memory for memory constrained boards like cse.

099b9ae7b7 arm: zynq: Enable BLK when needed
There is no reason to enable BLK by default for all boards which is just
increasing memory footprint for memory contrained boards like cse.
zc770s are also saving some space.

ae5326a6b3 serial: Make full device search optional
Commit 608b0c4ad4 ("serial: Use next serial device if probing fails")
added code to search for more serial devices if the default one was not
probed correctly.

Unfortunately, that breaks omap3_evm. So while investigating why that is
the case, let's disable the full search for everyone but bcm283x where it
is needed.
