MicroBlaze V is new AMD/Xilinx soft-core 32bit RISC-V processor IP. It is hardware compatible with classic MicroBlaze processor. The patch contains initial wiring and configuration for initial HW design with memory, cpu, interrupt controller, timers and uartlite console (interrupt controller is listed but U-Boot is not using it). Provided DT is just describing one configuration and should be taken only as example.

|
On Zynq and ZynqMP U-Boot SPL (or U-Boot proper if
|
|
ZYNQMP_PSU_INIT_ENABLED is set) is responsible for some
|
|
basic initializations, such as enabling peripherals and
|
|
configuring pinmuxes. The PS init file (called
|
|
psu_init_gpl.c on ZynqMP, ps7_init_gpl.c for Zynq-7000)
|
|
contains the code for such initializations.
|
|
|
|
U-Boot contains PS init files for some boards, but each of
|
|
them describes only one specific configuration. Users of a
|
|
different board, or needing a different configuration, can
|
|
generate custom files using the Xilinx development tools.
|
|
|
|
There are three ways to give a PS init file to U-Boot:
|
|
|
|
1. Set this variable to the path, either relative to the
|
|
source tree or absolute, where the psu_init_gpl.c or
|
|
ps7_init_gpl.c file is located. U-Boot will build this
|
|
file.
|
|
|
|
2. If you leave an empty string here, U-Boot will use
|
|
board/xilinx/zynq/$(CONFIG_DEFAULT_DEVICE_TREE)/ps7_init_gpl.c
|
|
for Zynq-7000, or
|
|
board/xilinx/zynqmp/$(CONFIG_DEFAULT_DEVICE_TREE)/psu_init_gpl.c
|
|
for ZynqMP.
|
|
|
|
3. If the above file does not exist, U-Boot will use
|
|
board/xilinx/zynq/ps7_init_gpl.c for Zynq-7000, or
|
|
board/xilinx/zynqmp/psu_init_gpl.c for ZynqMP. This file
|
|
is not provided by U-Boot, you have to copy it there
|
|
before the build.

help
|
|
This option enables FRU commands to capture and display FRU
|
|
information present in the device. The FRU Information is used
|
|
to primarily to provide "inventory" information about the boards
|
|
that the FRU Information Device is located on.

help
|
|
Xilinx System Controller (SC) FRU format is describing boards from two
|
|
angles. One from DUT and then from SC. DUT is default option for
|
|
the main CPU. SC behaves more or less as slave and have different ID.
|
|
If you build U-Boot for SC you should enable this option to get proper
|
|
MAC address.
