327381e8b5 colibri_imx7: use preboot for fdtfile evaluation
Enable and set preboot var with fdtfile evaluation.
preboot will be checked and run immediately before starting the
CONFIG_BOOTDELAY countdown and/or running the auto-boot command resp.
entering interactive mode.

This provides possibility to use different boot cmds in interactive mode
without manual setting fdtfile value, as it it's already evaluated
before entering interactive mode.

7bdfe85929 mpc83xx, keymile boards: enable DM_ETH and add DTS
enable DTS support for keymile mpc83xx based boards.

get rid of compile warning:
===================== WARNING ======================
This board does not use CONFIG_DM_ETH (Driver Model
for Ethernet drivers). Please update the board to use
CONFIG_DM_ETH before the v2020.07 release. Failure to
update by the deadline may result in board removal.
See doc/driver-model/migration.rst for more info.
====================================================

Therefore done:
- add DTS for all mpc83xx based boards from keymile
  mainly they are not mainlined to linux.
- add u-boot specific dtsi
- add stdout-path
- add missing ucc4 par_io definitions, which were
  in board code, but not in linux DTS
- remove not used ethernet nodes

  as now qe works with DM and DM_ETH support.
- fix mailaddress from Holger

Series-changes: 2
- add comments from Qiang Zhao:
  - add device node documentation
  - I did not drop the dm_qe_uec_phy.c and use drivers/net/fsl_mdio.c
    because using drivers/net/fsl_mdio.c leads in none existent
    udevice mdio@3320
    instead boards with DM ETH support should use now this
    driver.
- remove RFC tag

Commit-notes:

- I let the old none DM based implementation in code
  so boards should work with old implementation.
  This Code should be removed if all boards are converted
  to DM/DTS.

- add the DM based qe uec driver under drivers/net/qe

- Therefore copied the files uccf.c uccf.h uec.h from
  drivers/qe. So there are a lot of Codingstyle problems
  currently. I fix them in next version if this RFC
  patch is OK or it needs some changes.

- The dm based driver code is now under drivers/net/qe/dm_qe_uec.c
  Used a lot of functions from drivers/qe/uec.c

- seperated the PHY specific code into seperate file
  drivers/net/qe/dm_qe_uec_phy.c

  powerpc, mpc83xx: fix codingstyle issues for qe_io.c

Commit-notes:
Open questions / discussion:

- I let the old none DM based implementation in code
  so boards should work with old implementation.

  This should be removed if all boards are converted to
  DM/DTS.

- Unfortunately linux DTS does not use "pinctrl-"
  properties, instead "pio-handle" properties.

  Even worser old U-Boot code initializes all pins
  defined in "const qe_iop_conf_t qe_iop_conf_tab[]"
  table in board code. As linux does the same I decided
  to also scan through all subnodes containing "pio-map"
  property and initialize them too.

  The proper solution would be to check for "pio-handle"
  when a device is probed.

81d0cef3b2 lib: fdt: Fix fdtdec_setup_mem..() conversion to livetree API
Repair incorrectly negated condition in the original patch which broke
DT memory node parsing on everything which has more than one DT memory
node, e.g. R-Car3.

In case multiple valid memory nodes are present in the DT, the original
patch would complete parsing cycle for the first memory node, then move
on to the next one, identify it as a valid, and end the parsing. The fix
is to invert the condition, to make the code behave as it did before the
livetree conversion, so it would continue parsing the subsequent memory
nodes as well.

c091bb0499 env: ti: j721e-evm: Update rproc_fw_binaries env variable for J7200
The J7200 SoCs have different number of remote processors, but reuse
the same environment settings as the J721E SoCs. The current env
variable rproc_fw_binaries is geared towards J721E SoCs and is
incorrect for J7200 SoCs. Please see the logic originally added in
commit 0b4ab9c9a7 ("env: ti: j721e-evm: Add support to boot rprocs
including R5Fs and DSPs").

Fix this by defining the DEFAULT_RPROCS macro appropriately using
the corresponding TARGET_EVM Kconfig symbol. This macro is used by
the 'rproc_fw_binaries' env variable in the common remoteproc env
header file k3_rproc.h.

The list of R5F cores to be started before loading and booting the
Linux kernel are as follows, and mainly comprises of the Main R5FSS0
cores in this order:
   Main R5FSS0 (Split) Core0 : 2 /lib/firmware/j7200-main-r5f0_0-fw
   Main R5FSS0 (Split) Core1 : 3 /lib/firmware/j7200-main-r5f0_1-fw

The MCU R5FSS0 is in LockStep mode and is expected to be booted by
R5 SPL, so it is not included in the list. The order of rprocs to
boot cannot be really modified as only the Main R5FSS0 cores are
involved and Core0 has to be booted first always before the
corresponding Core1.

subsystems/clusters. One R5F cluster is present within the MCU
domain (MCU_R5FSS0), and the other one is present within the MAIN
domain (MAIN_R5FSS0). Each of these can be configured at boot time
to be either run in a LockStep mode or in an Asymmetric Multi
Processing (AMP) fashion in Split-mode. These subsystems have 64 KB
each Tightly-Coupled Memory (TCM) internal memories for each core
split between two banks - ATCM and BTCM (further interleaved into
two banks). The TCMs of both Cores are combined in LockStep-mode
to provide a larger 128 KB of memory.

Add the DT node for the MAIN domain R5F cluster/subsystem, the two
R5F cores are added as child nodes to the main cluster/subsystem node.
The cluster is configured to run in Split-mode by default, with the
ATCMs enabled to allow the R5 cores to execute code from DDR with
boot-strapping code from ATCM. The inter-processor communication
between the main A72 cores and these processors is achieved through
shared memory and Mailboxes.

7873e9df8f armv8: K3: j7200: Add custom MMU support
The A72 U-Boot code can load and boot a number of the available
R5FSS Cores on the J7200 SoC. Change the memory attributes for the
DDR regions used by the remote processors so that the cores can see
and execute the proper code.

The J7200 SoC has less number of remote processors compared to J721E,
so use less memory for the remote processors. So, a separate table
based on the current J721E table is added for J7200 SoCs, and selected
using the appropriate Kconfig CONFIG_TARGET_J7200_A72_EVM symbol.

6aa3b740c3 remoteproc: k3-r5: Add support for J7200 R5Fs
The K3 J7200 SoC family has a revised R5F sub-system and contains a
subset of the R5F clusters present on J721E SoCs. The integration of
these clusters is very much similar to J721E SoCs otherwise.

The revised IP has the following two new features:
 1. TCMs are auto-initialized during module power-up, and the behavior
    is programmable through a MMR bit controlled by System Firmware.
 2. The LockStep-mode allows the Core1 TCMs to be combined with the
    Core0 TCMs effectively doubling the amount of TCMs available.
    The LockStep-mode on previous SoCs could only use the Core0 TCMs.
    This combined TCMs appear contiguous at the respective Core0 TCM
    addresses.

Add the support to these clusters in the K3 R5F remoteproc driver
using J7200 specific compatibles and revised logic accounting for
the above IP features/differences.

ca569e9bbe dt-bindings: remoteproc: k3-r5f: Update bindings for J7200 SoCs
The K3 J7200 SoCs have two dual-core Arm R5F clusters/subsystems, with
2 R5F cores each, one in each of the MCU and MAIN voltage domains.

These clusters are a revised version compared to those present on
J721E SoCs. Update the K3 R5F remoteproc bindings with the compatible
info relevant to these R5F clusters/subsystems on K3 J7200 SoCs.

a9e5caf596 env: ti: j721e-evm: Limit scope of rproc env variables used by R5 SPL
The commit 316c927135 ("include: configs: j721e_evm: Add env variables
for mcu_r5fss0_core0 & main_r5fss0_core0") added four different new env
variables 'addr_mainr5f0_0load', 'name_mainr5f0_0fw', 'addr_mcur5f0_0load'
and 'name_mcur5f0_0fw' to the generic environment, but these are only
needed and used in R5 SPL for early-booting the MCU R5FSS0 and Main
R5FSS0 Core0 on J721E SoCs.

These are not really needed for A72 U-Boot, so limit the scope of
these variables only to R5 SPL. While at this, also fix the loadaddr
variable values to include the hex prefix like with other such env
variables.

3c195299a8 configs: j721e_evm: Add Main R5FSS1 Core1 to default rproc boot list
The default rproc list currently used by A72 U-Boot to boot various
remote processors include the Main R5FSS0 (Split-mode) Core1, Main
R5FSS1 (LockStep mode) Core0 and the three DSPs. The Main R5FSS1 cluster
is configured for Split mode by default in the dts now, so add the
Main R5FSS1 Core1 (rproc #5) to the default rproc boot list. This
core is now booted after the Main R5FSS1 Core0 and before the DSPs.

The order of the rprocs to boot can always be changed at runtime if
desired by overwriting the 'rproc_fw_binaries' environment variable
at U-boot prompt. Note that the R5FSS Core1 cannot be booted before
its associated Core0.

Switch the MAIN R5FSS1 cluster to be configured for Split-mode as the
default so that two different applications can be run on each of the
R5F cores in performance mode. LockStep-mode would be available only
on SoCs efused with the appropriate bit, and Split-mode is the mode
that is available on all J721E SoCs.
