The SYS_BOOT-based fallback shouldn't only check for one of the conditions of

conditions for each type of boot device again.
For instance, this behaviour would trigger the fallback for UART when
BOOT_DEVICE_UART is defined, CONFIG_SPL_YMODEM_SUPPORT is enabled (which should
be a show-stopper) and e.g. BOOT_DEVICE_USB is enabled and not
CONFIG_SPL_USB_SUPPORT.
Separating the logic for USB and UART solves this.
In addition, this adds support for more peripheral devices (USBETH and CPGMAC)

lib/display_options: Fix print_freq
Build without CONFIG_SPL_SERIAL_SUPPORT does not print the cpu freq.
I have seen this in the odroid U3 board, where on boot one sees this:
CPU: Exynos4412 @ GHz
instead of:
CPU: Exynos4412 @ 1 GHz
I am assuming that this change was done to get rid of compiler
warnings related to unused variables when building with
CONFIG_SPL_SERIAL_SUPPORT not being defined in an SPL build.

image: Fix loop condition to avoid warning
GCC 5.1 starts warning for comparisons such as !a > 0, assuming that the
negation was meant to apply to the whole expression rather than just the
left operand.
Indeed the comparison in the FIT loadable code is confusingly written,
though it does end up doing the right thing. Rewrite the condition to be
more explicit, that is, iterate over strings until they're exhausted.

x86: crownbay: Support Topcliff integrated pci uart devices with driver model
In order to make a pci uart device node to be properly bound to its

Change all pci bridge nodes under root pci node to use "pci-bridge"

dm: core: Fix code reentrancy issue in device_probe_child()
The device might have already been probed during the call to
device_probe() on its parent device (e.g. PCI bridge devices).
In its parent device's probe routine, it might probe all of
its child devices via device_probe() thus the codes reenter

So far we only enabled one legacy serial port on the SMSC LPC47m
superio chipset on Intel Crown Bay board. As the board also has
dual PS/2 ports routed out, enable the keyboard controller which
is i8042 compatible so that we can use PS/2 keyboard and mouse.
In order to make PS/2 keyboard work with the VGA console, remove
CONFIG_VGA_AS_SINGLE_DEVICE. To boot Linux kernel with PIC mode
using PIRQ routing table, adjust the mask in the device tree to
reserve irq12 which is used by PS/2 mouse.

video: cfb_console: Allow VGA device to work without i8042 keyboard
So far if CONFIG_VGA_AS_SINGLE_DEVICE is not defined, the VGA device
will try to initialize a keyboard device (for x86, it is i8042). But
if i8042 controller initialization fails (eg: there is no keyboard
connected to the PS/2 port), drv_video_init() just simply returns.
This kills the opportunity of using a usb keyboard later with the vga
console, as the vga initialization part is actually ok, only keyboard
part fails. Change the code logic to allow this.

x86: i8042: Correctly initialize the controller
The existing i8042 keyboard controller driver has some issues.
First of all, it does not issue a self-test command (0xaa) to the
controller at the very beginning. Without this, the controller
does not respond to any command at all. Secondly, it initializes
the configuration byte register to turn on the keyboard's interrupt,
as U-Boot does not normally allow interrupts to be processed.
Finally, at the end of the initialization routine, it wrongly
sets the controller to disable all interfaces including both
keyboard and mouse.
