Modify the configuration naming to be generic to xilinx rather than specific to Versal. The offset value is different for Zynq and ZynqMP to avoid overlapping with FSBL. Signed-off-by: Ibai Erkiaga <ibai.erkiaga-elorza@xilinx.com> Signed-off-by: Michal Simek <michal.simek@xilinx.com>

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.
