This is the 11th version of patchset to adds support for Intel Arria 10 SoC FPGA
driver. This version mainly resolved comments from Dinh in [v10]. This series is
working on top of u-boot-socfpga.git - http://git.denx.de/u-boot-socfpga.git
[v10]: https://www.mail-archive.com/u-boot at lists.denx.de/msg252583.html
v10 -> v11 changes:
-----------------
- Changed the commit header of patch 3 and patch 4 to "kconfig:", previously was
"arm: socfpga:".
- Cleaned up commit old message on patch 5.

Remove parameter from socfpga_bridges_reset(), and keeping this function
for single purpose which is just triggering reset on bridges.
socfpga_reset_deassert_bridges_handoff() can be called for releasing reset
on any bridges based on the bridge setting defined in fdt.

Move FPGA driver which is Gen5 specific code into Gen5 driver file
and keeping common FPGA driver intact. All the changes are still keeping
in driver/fpga/ and no functional change. Subsequent patch would move
FPGA manager driver from arch/arm into driver/fpga/.

Enable FPGA driver build for SPL because FPGA driver is needed for SPL
to configure and getting DDR up before loading U-boot into DDR and
booting from there.

That doesn't answer my question. Did you do something like
make savedefconfig
cp defconfig configs/foo_defconfig
?

Sorry for confusing, i don't know make savedefconfig is for creating
new defconfig based on .config until i googled it. CONFIG_FPGA_ALTERA=y
was put into their defconfigs after running moveconfig script.
