5fb3e09d97 ti: omap5: Switch to generic distro boot for non-Android cases
Remove the environment support for various legacy boot methods.  With
this, we will now default to booting any distribution that follows the
generic distro boot framework and no longer attempt to boot various
legacy (to this SoC) scripts/etc.  Note that if we do not find anything
here we will continue to try and Android methods and will start by
trying fastboot.

02bfcc5c3a remoteproc: pru: Add support for various PRU cores on K3 AM65x SoCs
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

7bafe88620 soc: ti: pruss: Add a platform driver for PRUSS in TI SoCs
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.

776e25788c arm: dts: k3-am64-main: Reserve OCMRAM for DMSC-lite and secure proxy communication
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.

Earlier, the region 0x701c0000 to 0x701dffff was firewalled off because of
a bug in SYSFW. In the v2021.05 release of SYSFW this bug has been fixed
and this region can now be used for other allocations.

Therefore, move TF-A's load address to 0x701c0000 and update its location
in the device tree node. Also, increase the size allocated for TF-A to
account for future expansions.

2f91fc4003 x86: Ensure the e820 map is installed in all cases
This is a revert of a recent logic change in setup_zimage(). We do
actually need to install this information always. Change it to install
from the Coreboot tables if available, else the normal source.

With the new 2021.04 we have a new version of Chromium OS boot, which
supports sandbox, coral and coral-on-coreboot. Add documentation for
this.

1c56469ce1 dtoc: Check that a parent is not missing
With of-platdata-inst we want to set up a reference to each devices'
parent device, if there is one. If we find that the device has a parent
(i.e. is not a root node) but it is not in the list of devices being
written, then we cannot create the reference.

Report an error in this case, since it indicates that the parent node
is either missing a compatible string, is disabled, or perhaps does not
have any properties because it was not tagged for SPL.

54e0bd1728 x86: cros: Check ROM exists before building vboot
All the x86 devicetree files are built at once, whichever board is
actually being built. If coreboot is the target build, CONFIG_ROM_SIZE
is not defined and samus cannot build Chromium OS verified boot. Add
this condition to avoid errors about CONFIG_ROM_SIZE being missing.

e74d0ec80b x86: coreboot: Document the memory map
Add information about memory usage when U-Boot is started from coreboot.
This is useful when debugging. Also, since coreboot takes a chunk of
memory in the middle of SDRAM for use by PCI devices, it can help avoid
overwriting this with a loaded kernel by accident.

Set up coral so that it can boot from coreboot, even though it is a
bare-metal build. This helps with testing since the same image can be used
in both cases.

7052968707 x86: Do cache set-up by default when booting from coreboot
A recent change to disable cache setup when booting from coreboot
assumed that this has been done by SPL. The result is that for the
coreboot board, the cache is disabled (in start.S) and never
re-enabled.

If the cache was turned off, as it is on boards without SPL, we should
turn it back on. Add this new condition.

0f5ca1d1f1 x86: Update the MP constants to avoid conflicts
These constants conflict with error codes returned by the MP
implementation when something is wrong. In particular, mp_first_cpu()
returns MP_SELECT_BSP when running without multiprocessing enabled.
Since this is -2, it is interpreted as an error by callers, which
expect a positive CPU number for the first CPU.

Correct this by using a different range for the pre-defined CPU
numbers, above zero and out of the range of possible CPU values. For
now it is safe to assume there are no more than 64K CPUs.

This fixes the 'mtrr' command when CONFIG_SMP is not enabled.

92873f83d1 x86: Don't set up MTRRs if previously done
When starting U-Boot from a previous-stage bootloader we presumably don't
need to set up the variable MTRRs. In fact this could be harmful if the
existing settings are not what U-Boot uses.

Skip that step in this case.
