Xilinx ZynqMP also contains dual Cortex R5 which can run U-Boot.
This patch is adding minimal support to get U-Boot boot.
U-Boot on R5 runs out of DDR with default configuration that's why
DDR needs to be partitioned if there is something else running on arm64.
Console is done via Cadence uart driver and the first Cadence Triple
Timer Counter is used for time.
This configuration with uart1 was tested on zcu100-revC.

separate Kconfig symbols can be added for CPU_V7R and CPU_V7M and
can co exist in the same folder.

The syscon implementation in U-Boot is different from that in Linux.
Thus, DT files imported from Linux do not work for U-Boot.
In U-Boot driver model, each node is bound to a dedicated driver
that is the most compatible to it. This design gets along with the
concept of DT, and the syscon in Linux originally worked like that.
However, Linux commit bdb0066df96e ("mfd: syscon: Decouple syscon
interface from platform devices") changed the behavior because it is
useful to let a device bind to another driver, but still work as a
syscon provider.
That change had happened before U-Boot initially supported the syscon
driver by commit 6f98b7504f ("dm: Add support for generic system
controllers (syscon)"). So, the U-Boot's syscon works differently
from the beginning. I'd say this is mis-implementation given that
DT is not oriented to a particular project, but Linux is the canon
of DT in practice.
The problem typically arises in the combination of "syscon" and
"simple-mfd" compatibles.
In Linux, they are orthogonal, i.e., the order between "syscon" and
"simple-mfd" does not matter at all.
Assume the following compatible.
compatible = "foo,bar-syscon", "syscon", "simple-mfd";
In U-Boot, this device node is bound to the syscon driver
(driver/core/syscon-uclass.c) since the "syscon" is found to be the
most compatible. Then, syscon_get_regmap() succeeds.
However,
compatible = "foo,bar-syscon", "simple-mfd", "syscon";
does not work because this node is bound to the simple-bus driver
(drivers/core/simple-bus.c) in favor of "simple-mfd" compatible.
The compatible string "syscon" is just dismissed.
Moreover,
compatible = "foo,bar-syscon", "syscon";
works like the first case because the syscon driver populates the
child devices. This is wrong because populating children is the job
of "simple-mfd" (or "simple-bus").
This commit ports syscon_node_to_regmap() from Linux. This API
does not require the given node to be bound to a driver in any way.

Putting zero length array at the end of struct is a common technique

As far as I understood the code, regmap->base is an alias of

just ugly.

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.
In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.
This commit changes all instances where we have multiple licenses (in
these cases, dual license) declared in the SPDX-License-Identifier tag.
In this case we change from listing "LICENSE-A LICENSE-B" or "LICENSE-A
or LICENSE-B" or "(LICENSE-A OR LICENSE-B)" to "LICENSE-A OR LICENSE-B"
as per the Linux Kernel style document. Note that parenthesis are

The 'SDHCI_QUIRK_NO_HISPD_BIT' is used wrong here. The purpose of this

Some IP-core implementations of the SDHCI have different troubles on the
silicon where they are placed.
On ZYNQ platform for example Xilinx doesn't accept the hold timing of an
eMMC chip which operates in High-Speed mode and must be forced to
operate in non high-speed mode. To get rid of this
"SDHCI_QUIRK_BROKEN_HISPD_MODE" is introduced.
For more details about this refer to the Xilinx answer-recor #59999https://www.xilinx.com/support/answers/59999.html
This commit:
- doesn't set HISPD bit on the host-conroller
- reflects this fact within the host-controller capabilities
Upon this the layer above (mmc-driver) can setup the card correctly.
Otherwise the MMC card will be switched into high-speed mode and causes
possible timing violation on the host-controller side.
