2bc1f2b592 mtd: denali_spl: do not allocate page_buffer in .bss section
Since commit 2580a2a7e7 ("mtd: nand: Increase max sizes of OOB and
Page size"), three boards (ph1_ld4, ph1_pro4, ph1_sld8) fail to build
with the following error message:
  arm-linux-gnueabi-ld.bfd: SPL image plus BSS too big

They compile drivers/mtd/nand/denali_spl.c and it has a page_buffer
as static data:

    static uint8_t page_buffer[NAND_MAX_PAGESIZE];

This buffer required 8KB in .bss section before that commit and now
it has been increased to 16KB.  Given limited code/memory size for SPL,
it is not a good idea to allocate a page buffer statically.  In the
first place, the load address 'dst' can be used as a page buffer.

8ceb34a1d1 omap-common: SYS_BOOT fallback logic correction and support for more devices
The SYS_BOOT-based fallback shouldn't only check for one of the conditions of
use and then let the switch/case handle each boot device without enforcing the
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)
to the fallback mechanism. Note that the USBETH boot device should always be
different from the USB boot device (each should match a different bootrom
handoff case).

401f2d91ac ARM: keystone2: configs: Move SP to end of u-boot section
Currently u-boot stack is defined at the beginning of MSMC RAM.
This is a problem for uart boot mode as ROM downloads directly to
starting of MSMC RAM.
Fixing it by moving stack to the end of u-boot section and shifting
SYS_TEXT_BASE to the start of MSMC RAM.
Updated division of MSMC RAM is shown below:
	-----------------------------------------
	|		|	|		|
	| U-Boot text	|U-Boot	| SPL text	|
	| download	| Stack	| Download +	|
	|		|	| SPL_BSS +	|
	|		|	| SPL_STACK	|
	-----------------------------------------
	[1]		[2]	[3]		[4]

[1] SYS_TEXT_BASE (Start of MSMC RAM)
[2] SPL_TEXT_BASE - GBL_DATA_SIZE
[3] SPL_TEXT_BASE
[4] END of SPL

[1] + [2] is at least 1M on all platforms, so no chance of overlap.

76cff2b108 ARM: DRA74-evm: Use SMA_1 spare register to workaround DP83865 phy on SR2.0
DP83865 ethernet phy used on DRA74x-evm is quirky and the datasheet
provided IODELAY values for standard RGMII phys do not work.

Silicon Revision(SR) 2.0 provides an alternative bit configuration
that allows us to do a "gross adjustment" to launch the data off a
different internal clock edge. Manual IO Delay overrides are still
necessary to fine tune the clock-to-data delays. This is a necessary
workaround for the quirky ethernet Phy we have on the platform.

NOTE: SMA registers are spare "kitchen sink" registers that does
contain bits for other workaround as necessary as well. Hence the
control for the same is introduced in a generic SoC specific, board
generic location.

In order to make a pci uart device node to be properly bound to its
driver, we need make sure its parent node has a compatible string
which matches a driver that scans all of its child device nodes in
the device tree.

Change all pci bridge nodes under root pci node to use "pci-bridge"
compatible driver, as well as corresponding <reg> properties to
indicate its devfn. At last, adding "u-boot,dm-pre-reloc" to each
of these nodes for driver model to initialize them before relocation.

cdeb2ba99c 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
device_probe_child(). To support code reentrancy, test these
allocated memory against NULL to avoid memory leak, and return
to the caller if dev->flags has DM_FLAG_ACTIVATED set after
device_probe() returns, so that we don't mess up the device.

4dd02a752c x86: crownbay: Enable on-board SMSC superio keyboard controller
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.

8ceb2429c9 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.
