[U-Boot] [PATCH v4 0/4] Stratix10 FPGA reconfiguration support

[chee.hong.ang at intel.com]

From: "Ang, Chee Hong" <chee.hong.ang@intel.com>

Summary of v4 changes:
- Patch 1/4, 2/4 and 4/4 are unchanged
- Patch 3/4:
  - implement socfpga_fpga_add() as global weak function.
  - add arch/arm/mach-socfpga/fpga_device.c to override
    socfpga_fpga_add() for Cyclone/Stratix platforms

v3 patchsets:

I'm not sure I completely followed the discussion of previous versions
of this series, but is this really the coding style U-Boot wants?
I would have thought weak functions are used for unknown extension
points (multiple architectures or boards), but this is a config option
in a defined set of files. In my opinion, using weak here is not the
right thing to do.

I'd rather add a header file fpga_device.h that declares this function
depending on CONFIG_FPGA.

My understanding is that the goal was to deduplicate the function for
Gen5 somehow, but you're right, this looks odd.

This function should always be declared for SoCFPGA, except with
different tables for different FPGAs.

This functions is general to all platforms except it is adding
different table for different platform. But this function is depending
on whether CONFIG_FPGA is defined or not. So if I declare this function
as empty function if CONFIG_FPGA is not defined then it would be
something similar to what I already addressed in previous v3 patchsets.
In v3 patchsets the tables and socfpga_fpga_add() function were already
declared in arch/arm/mach-socfpga/misc.c.
Can you guys take a look at v3 patchsets ?
