[meta-xilinx] [PATCH 0/5] Updates to u-boot-xlnx

[andrey]

Hello Nathan,

We are now starting production of our Zynq-based product and are trying to update a 2-year old software to the current state of Yocto. We do not use Vivado to manage the project, for the FPGA development we use alternative Eclipse-based integration that remotely launches specific Vivado tools. We had to replace some of the Xilinx primitives models (such as https://github.com/Elphel/gtxe2_gpl )  to be able to simulate the complete project (it is now above 80% utilization) with the GPL-ed tools (Icarus+GTKWave). In 2013 we made  a replacement for Xilinx FSBL that at that time was violating the GNU GPL of the U-Boot. Later Xilinx had to comply with GPL and modified the license for the generated files, but we would still like to avoid Vivado for FSBL generation - it is extra work for us and is inconvenient to learn new GUI, re-enter the project data just to be able to generate boot loader.

The question is - does the current upstream U-Boot have all what is needed to create an alternative bootloader for Zynq (by updating our  https://github.com/Elphel/meta-ezynq ) or there are still some important functionality (common to all boards, not specific to particular ones and/or Vivado releases) in u-boot-xlnx that is not yet in available in the upstream?
