The K3 AM65x family of SoCs have the next generation of the PRU-ICSS
processor subsystem, commonly referred to as ICSSG. Each ICSSG processor
subsystem on AM65x SR1.0 contains two primary PRU cores and two new
auxiliary PRU cores called RTUs. The AM65x SR2.0 SoCs have a revised
ICSSG IP that is based off the subsequent IP revision used on J721E
SoCs. This IP instance has two new custom auxiliary PRU cores called
Transmit PRUs (Tx_PRUs) in addition to the existing PRUs and RTUs.
Each RTU and Tx_PRU cores have their own dedicated IRAM (smaller than
a PRU), Control and debug feature sets, but is different in terms of
sub-modules integrated around it and does not have the full capabilities
associated with a PRU core. The RTU core is typically used to aid a
PRU core in accelerating data transfers, while the Tx_PRU cores is
normally used to control the TX L2 FIFO if enabled in Ethernet
applications. Both can also be used to run independent applications.
The RTU and Tx_PRU cores though share the same Data RAMs as the PRU
cores, so the memories have to be partitioned carefully between different
applications. The new cores also support a new sub-module called Task
Manager to support two different context thread executions.
The driver currently supports the AM65xx SoC

The Programmable Real-Time Unit - Industrial Communication
Subsystem (PRU-ICSS) is present of various TI SoCs such as
AM335x or AM437x or the AM654x family. Each SoC can have
one or more PRUSS instances that may or may not be identical.
The PRUSS consists of dual 32-bit RISC cores called the
Programmable Real-Time Units (PRUs), some shared, data and
instruction memories, some internal peripheral modules, and
an interrupt controller. The programmable nature of the PRUs
provide flexibility to implement custom peripheral interfaces,
fast real-time responses, or specialized data handling.
Add support for pruss driver. Currently am654x family
is supported.

The final 128KB in SRAM is reserved by default for DMSC-lite code and
secure proxy communication buffer. The memory region used for DMSC-lite
code can be optionally freed up by secure firmware API[1]. However, the
buffer for secure proxy communication is not configurable. This default
hardware configuration is unique for AM64.
Therefore, indicate the area reserved for DMSC-lite code and secure proxy
communication buffer in the oc_sram device tree node.

When "mkimage -l" was run on a block device it would fail with

This patch identifies the "is a block device" case and reports it as
such, and if it knows how to determine the size of a block device on
the current OS, proceeds.
As shown in

The ST-Ericsson DB8500 SoC contains a MUSB OTG controller which
supports both host and gadget mode. For some reason there is
nothing special about it - add a simple glue driver for Ux500
that literally just sets up MUSB together with a generic PHY.
There are no SoC-specific registers etc needed to make USB work.
The new Ux500 glue driver is only tested to work with DM_USB
and DM_USB_GADGET. Both host and gadget mode work fine on
the u8500 "stemmy" board that is already present in U-Boot.

The AB8500 PMIC contains an USB PHY that needs to be set up in
device or host mode to make USB work properly. Add a simple driver
for the generic PHY uclass that allows enabling it.
The if (CONFIG_IS_ENABLED(USB_MUSB_HOST)) might be a bit strange.
The USB PHY must be configured in either host or device mode and
somehow the USB PHY driver must be made aware of the mode.
Actually, the MUSB driver used together with this PHY does not
support dynamic selection of host/device mode in U-Boot at the moment.
Therefore, one very simple approach that works fine is to select
the mode to configure at compile time. When the MUSB driver is
configured in host mode the PHY is configured in host mode, and
similarly when the MUSB driver is configured in device/gadget mode.

All devices based on ST-Ericsson Ux500 use a PMIC similar to AB8500
(Analog Baseband). There is AB8500, AB8505, AB9540 and AB8540
although in practice only AB8500 and AB8505 are relevant since the
platforms with AB9540 and AB8540 were cancelled and never used in
production.
In general, the AB8500 PMIC uses I2C as control interface, where the
different register banks are represented as separate I2C devices.
However, in practice AB8500 is always connected to a special I2C bus
on the DB8500 SoC that is controlled by the power/reset/clock
management unit (PRCMU) firmware.
Add a simple driver that allows reading/writing registers of the
AB8500 PMIC. The driver directly accesses registers from the PRCMU
parent device (represented by syscon in U-Boot). Abstracting it
further (e.g. with the i2c uclass) would not provide any advantage
because the PRCMU I2C bus is always just connected to AB8500 and
vice-versa.
The ab8500.h header is mostly taken as-is from Linux (with some
minor adjustments) to allow using similar code in both Linux and
U-Boot.

The U-Boot "stemmy" board is mainly intended to simplify booting
mainline Linux on various smartphones from Samsung based on ST-Ericsson
Ux500. While the mainline kernel is working great, there are still some
features missing there. In particular, it is currently not possible to
charge the battery when using the mainline kernel.
This means that it is still necessary to boot the downstream/vendor
kernel from Samsung sometimes to charge the device. That kernel is
ancient, still uses board files + ATAGS instead of device trees and
relies on a strange very long kernel command line hardcoded in the
Samsung bootloader.
Actually, since mainline is booted with device trees there is a very
simple way to make the old downstream kernel work as well: We can
simply take most of the ATAGS passed to U-Boot from the Samsung
bootloader and copy them as-is when booting a kernel without device
tree. That way the long command line and other needed ATAGS are copied
as-is without having to bother with them.
The only exception is the ATAG_INITRD - since the initrd is loaded
by U-Boot, the atag for that should be generated in U-Boot so it points
to the correct address. All other ATAGS are copied as-is and not
generated in U-Boot.
Also use the chance and provide a serial# for U-Boot by parsing the
ATAG_SERIAL that is also passed by the Samsung bootloader.

At the moment the "stemmy" board attempts to detect the RAM size with
a simple memory test (get_ram_size()). Unfortunately, this does not work
correctly for devices with 768 MiB RAM (e.g. Samsung Galaxy Ace 2
(GT-I8160), "codina"). Reading/writing memory after the 768 MiB RAM
succeeds but actually overwrites some earlier parts of the memory.
For U-Boot this does not result in any major problems, but on Linux
this will eventually lead to strange crashes because of the memory
corruption.
Since the "stemmy" U-Boot port is designed to be chainloaded from
the original Samsung bootloader, the most reliable way to get the
available amount of RAM is to look at the ATAGS passed by the Samsung
bootloader. Fortunately, the header used to generate ATAGS in U-Boot
(asm/setup.h) can also be easily used to parse them.
Also clarify and simplify stemmy.h a bit to make it more clear where
some of the magic values in there are actually coming from.

According to arch/arm/lib/crt0_64.S, the BSS section is "UNAVAILABLE"
and uninitialized before relocation. Also, it overlaps with the
appended DTB before relocation, so writing data into a variable
in the BSS section might corrupt the appended DTB.
Unfortunately, pinctrl-apq8016.c and pinctrl-apq8096.c do place the
"pin_name" variable in the BSS section (since it's uninitialized).
It's also used before relocation, when setting up the pinctrl for
the serial driver.
On DB410c this causes "GPIO_5" to be written into some part of an
appended DTB, e.g.:
80111820: edfe0dd0 9f100000 38000000 c00e0000 ...........8....
80111830: 28000000 11000000 10000000 00000000 ...(............
80111840: 4f495047 8800355f 00000000 00000000 GPIO_5..........
80111850: 00000000 00000000 01000000 00000000 ................
80111860: 03000000 04000000 00000000 02000000 ................
80111870: 03000000 04000000 0f000000 02000000 ................
80111880: 03000000 2d000000 1b000000 6c617551 .......-....Qual
80111890: 6d6d6f63 63655420 6c6f6e68 6569676f comm Technologie
Depending on the part of the DTB that is corrupted this might not
cause any problems, but it can also result in strange reboots
without any serial output.
Fortunately, in practice this does not cause issues on DB410c yet
because board_fdt_blob_setup() in dragonboard410c.c currently
overrides the appended DTB with the one passed by the previous
bootloader (LK) (which does not get corrupted).
DB820c does not have board_fdt_blob_setup() so I would expect it to
be affected by this problem. Perhaps everyone was just fortunate to
not compile an U-Boot configuration where the pin_name corrupts an
important part of the DTB.
Make sure "pin_name" is explicitly placed in the .data section
instead of .bss to fix this.
