arm: socfpga: arria10: Add qts-filter for Arria10 socfpga
Add a script to process HPS handoff data and generate a header for inclusion in u-boot specific devicetree addons. The header should be included in the top level of u-boot.dtsi. Signed-off-by: Dalon Westergreen <dalon.westergreen@intel.com> Signed-off-by: Ley Foon Tan <ley.foon.tan@intel.com>

Arria 10 generating the handoff header files for U-Boot SPL
|
||||
----------------------------------------------------------
|
||||
|
||||
A header file for inclusion in a devicetree for Arria10 can be generated
|
||||
by the qts-filter-a10.sh script directly from the hps_isw_handoff/hps.xml
|
||||
file generated during the FPGA project compilation. The header contains
|
||||
all PLL, clock, pinmux, and bridge configurations required.
|
||||
|
||||
Please look at the socfpga_arria10_socdk_sdmmc-u-boot.dtsi for an example
|
||||
that includes use of the generated handoff header.
|
||||
|
||||
Devicetree header generation
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
The qts-filter-a10.sh script can process the compile time genetated hps.xml
|
||||
to create the appropriate devicetree header.
|
||||
|
||||
|
||||
$ ./arch/arm/mach-socfpga/qts-filter-a10.sh \
|
||||
<hps_xml> \
|
||||
<output_file>
|
||||
|
||||
hps_xml - hps_isw_handoff/hps.xml from Quartus project
|
||||
output_file - Output filename and location for header file
|
||||
|
||||
The script generates a single header file names <output_file> that should
|
||||
be placed in arch/arm/dts.
