This patch synchronizes the am33xx SoC specific files with those from
Linux 4.20.0. Hence all board maintainers of am33xx based boards are
on the cc list.
The main purpose of this patch is to prevent further diverging of the
dts files from U-Boot and those from Linux. It aims to set the stage
for the synchronization of board specific dts files. Example: I'm the
maintainer of the PDU001 board: once this patch is applied successfully
I will make changes to the board specific dts file in Linux only and
then post a patch with a copy of this exact dts file to U-Boot. This
will make U-Boot and Linux remain in sync.
The stumbling block of https://patchwork.ozlabs.org/patch/943627 was
removed by the patch https://patchwork.ozlabs.org/patch/962428 from
Lokesh Vutla (many thanks!). This omap-serial driver allows using the
Linux am33xx.dtsi file in U-Boot.
Other changes to dts and dtsi files made by this patch are mainly to
prevent _new_ warnings during the build process. Especially the warning
at pinmux@800 stating 'unnecessary #address-cells/#size-cells without
"ranges" or child "reg"' was not removed. This warning is a good example
showing the benefit of the synchronization: if it needs to be fixed it
will be fixed in Linux and ported back to U-Boot.
Buildman reports all 46 am33xx SoC based boards to build fine, with
warnings of course. Nevertheless this patch should be tested thoroughly
on as many boards as possible to prevent any collateral damage.

This patch enables CONFIG_BLK as well as CONFIG_DM_MMC for the PDU001
board. It depends on Patrice Chotard's patch 'power: regulator: denied
disable on always-on regulator' which prevents power cycling the vmmc
supply. Without this patch the board will not boot as vmmc is
unfortunately used by other board components, not just eMMC and micro SD
card. Furthermore my patch 'dts: am335x-pdu001: Fix polarity of card
detection input' is required to boot from external micro SD card. Without
this patch no SD card will be detected and hence booting will fail.

When a micro SD card is inserted in the PDU001 card cage, the card
detection switch is opened and the corresponding GPIO input is driven
by a pull-up. Hence change the active level of the card detection
input from low to high.

Rock960 is a family of boards based on Rockchip RK3399 SoC from Vamrs.
It consists of Rock960 (Consumer Edition) and Ficus (Enterprise Edition)
96Boards.
Below are some of the key differences between both Rock960 and Ficus
boards:
1. Different host enable GPIO for USB
2. Different power and reset GPIO for PCI-E
3. No Ethernet port on Rock960
The common board support will be utilized by both boards. The device
tree has been organized in such a way that only the properties which
differ between both boards are placed in the board specific dts and
the reset of the nodes are placed in common dtsi file.

Some SanDisk Ultra cards trigger intermittent errors on detection
resulting in an -EOPNOTSUPP, when running at 50MHz.
Waveform analysis suggest that the level shifters that are used on the
RK3399-Q7 module (for voltage translation between the on-module
voltages and the 3.3V required on the card-edge) don't handle clock
rates at or above 48MHz properly. This change reduces the maximum
frequency on the external SD-interface to 40MHz (for a safety margin
of 20%).

This configuration is useful when you want to run small u-boot and
perform DDR memory test to make sure that DDR is properly configured.
It is use for board bringup because alternative u-boot memory tests is
quite good.
Configuration is running out of OCM.
As is done for others mini configurations 0x80 bytes for variables is
enough and only default variables are stored there.
Alternative memtest is enabled and also 2GB of DDR via DTS files.
Configuration is enabling ZYNQMP_PSU_INIT_ENABLED and include psu_init()
from zcu102 for testing purpose.
In case of size issue this can be moved to SPL configuration as is done
for mini_qspi configuration but it is not a problem now.
