This adds some additional DT labels which are handy when referring
to the nodes in derived DTS(I) files. It will also make the
definitions more consistent, e.g. by adding gsbi2_serial and
gsbi5_serial where we previously "only" had gsbi4_serial defined.
While at it, add missing spaces after some DT labels and remove one
useless empty line.

The BreadBee and the BreadBee Crust are the same PCB with a different
SoC mounted. There are two top level dts to handle this.
To avoid deduplicating the parts that are more related to the PCB than
the SoC (i.e. the voltage regs and LEDs) add a common dtsi that can
be included in both top level dts.

The Ericsson U300 platform was one of two ARM929 based SoC platforms for
mobile phones in ST-Ericsson after the merger of Ericsson with ST-NXP
into ST-Ericsson, the other one being the ST Nomadik.
The platform was not widely adopted in Linux based systems and was
replaced with the far superior ST-Ericsson U8500 in 2011, but Linus
Walleij kept maintaining the code for the whole time.
Linus continues to use the Nomadik machine, but decided to drop
u300 from the kernel as part of this year's spring cleaning.
Thanks for having maintained it all these years.

The smp8758 (tango4) SoC was the last generation of set-top-box chips
to come out of Sigma Designs, and support was added by Marc Gonzalez
and Måns Rullgård between 2015 and 2017, before the company went out of
business and the products were abandoned.
The chip is used in some set-top-boxes such as the Popcorn Hour A-500,
which could have seen some adoption by hobbyists. This has not happened
in the past four years, and support for the more widely used MIPS based
SoCs was never merged at all.
Thanks to Marc and Måns for maintaining for the past years even after the
death of the platform.

The ZTE ZX set-top-box SoC platform was added in 2015 by Jun Nie, with
Baoyou Xie and Shawn Guo subsequently becoming maintainers after the
addition of the 64-bit variant.
However, the only machines that were ever supported upstream are the
reference designs, not actual set-top-box devices that would benefit
from this support. All ZTE set-top-boxes from the past few years seem
to be based on third-party SoCs. While there is very little information
about zx296702 and zx296718 on the web, I found some references to other
chips from the same family, such as zx296716 and zx296719, which were
never submitted for upstream support. Finally, there is no support for
the GPU on either of them, with the lima and panfrost device drivers
having been added after work on the zx platform had stopped.
Shawn confirmed that he has not seen any interest in this platform for
the past four years, and that it can be removed.
Thanks to Jun and Shawn for maintaining this platform over the past
five years.

The SiRF Prima2 and Atlas platform code was contributed by Cambridge
Silicon Radio (CSR) after aquiring the original SiRF company, and
maintained by Barry Song. CSR was subsequently acquired by Qualcomm,
who no longer have an interest in maintaining the SoC platform but
instead have released more recent SoCs for the same market in the
Snapdragon family.
As Barry is no longer working for the company, nobody else there
wants to maintain it, and there are no third-party users, the
best way forward seems to be to completely remove it.
Thanks to Barry for maintaining the platform for the past ten years.

Late devicetree changes for omaps for v5.11 merge window
Here are few more late changes that would be nice to get into v5.11:
- More updates to use cpsw switchdev driver
- Enable gta04 PMIC power management
- Updates for dra7 for ECC support, 1.8GHz speed and keep the
ldo0 regulator always on as specified in the data manual
The PHY address bit 2 is configured by the LED pin. Attaching a LED
to this pin is not sufficient to guarantee this configuration pin is
correctly read. This leads to some platforms having their PHY at
address 0 and others at address 4.
If there is no phy-handle specified, the FEC driver will scan the PHY
bus for a PHY and use that. Consequently, adding the DT configuration
of the PHY and the phy properties to the FEC driver broke some boards.
Fix this by removing the phy-handle property, and listing two PHY
entries for both possible PHY addresses, so that the DT configuration
for the PHY can be found by the PHY driver.

There are two KSZ8081 on the imx6ul-14x14-evk: one has the reset line
controlled by the Q1 output of the 74LV595PW expander, and the other
by the Q2 output.
The KSZ8081 datasheet states that the tsr parameter (Stable supply
voltage (VDDIO, VDDA_3.3) to reset high) to be 10ms minimum and
"After the de-assertion of reset, wait a minimum of 100 µs before
starting programming on the MIIM (MDC/MDIO) interface."

Currently the 74LV595PW GPIO expander is not functional because its OE
pin is not driven low.
Make it funcional by passing the 'enable-gpios' property inside the
GPIO expander node.
After putting the OE pin in low state, the outputs of the 74LV595PW all
go low.
The two KSZ8081 Ethernet PHYs reset lines are driven from the
the GPIO expander and as they remain low, this causes the Ethernet
PHYs not to be detected.
There is one solution to this problem as suggested by Andrew Lunn:
"Some devices will respond to MDIO while held in reset, some don't.
If your PHYs don't you need to add a compatible of the form
ethernet-phy-id[a-f0-9]{4}\\.[a-f0-9]{4}$ with the PHY ID. The PHY
will then be probed, independent of if it can be found on the bus or
not, and that probing will enable the GPIO."
So pass the "ethernet-phy-id0022.1560" for the KSZ8081 PHYs so that they
both can be functional after 74LV595PW is activated.

The Ux500 platforms have some memory carveouts set aside for
communicating with the modem and for the initial secure software
(ISSW). These areas are protected by the memory controller
and will result in an external abort if accessed like common
read/write memory.
On the legacy boot loaders, these were set aside by using
cmdline arguments such as this:
mem=96M@0 mem_mtrace=15M@96M mem_mshared=1M@111M
mem_modem=16M@112M mali.mali_mem=32M@128M mem=96M@160M
hwmem=127M@256M mem_issw=1M@383M mem_ram_console=1M@384M
mem=638M@385M
Reserve the relevant areas in the device tree instead. The
"mali", "hwmem", "mem_ram_console" and the trailing 1MB at the
end of the memory reservations in the list are not relevant for
the upstream kernel as these are nowadays replaced with
upstream technologies such as CMA. The modem and ISSW
reservations are necessary.
This was manifested in a bug that surfaced in response to
commit 7fef431be9 ("mm/page_alloc: place pages to tail in __free_pages_core()")
which changes the behaviour of memory allocations
in such a way that the platform will sooner run into these
dangerous areas, with "Unhandled fault: imprecise external
abort (0xc06) at 0xb6fd83dc" or similar: the real reason
turns out to be that the PTE is pointing right into one of
the reserved memory areas. We were just lucky until now.
We need to augment the DB8500 and DB8520 SoCs similarly
and also create a new include for the DB9500 used in the
Snowball since this does not have a modem and thus does
not need the modem memory reservation, albeit it needs
the ISSW reservation.
