To: u-boot
Restructure clock manager driver in the preparation to support A10.
Move the Gen5 specific code to _gen5 files. No functional change.
Change all uint32_t to u32 and change to use macro BIT(n) for bit shift.

Please add a -C when you run format-patch, you'll get something like this:
5 files changed, 104 insertions(+), 947 deletions(-)
copy arch/arm/mach-socfpga/{clock_manager.c => clock_manager_gen5.c} (88%)
copy arch/arm/mach-socfpga/include/mach/{clock_manager.h =>
clock_manager_gen5.h} (87%)
It it make things a bit smaller to review for simple file copies.
Thanks,

Restructure reset manager driver in the preparation to support A10.
Move the Gen5 specific code to _gen5 files. Minor update in socfpga_per_reset().
No functional change.

Do you mean by the reset_uart() below? In the last review, you comment
that uart_com_port() is in later patch (misc path) of reset manager
patch. So, I moved this function to this here. Let me know if you
prefer a new patch this reset_uart().

It just doesn't seem right to have reset-manager code bits in SPL patch,
that's all . Do you mean you have the uart_com_port() function
in misc.c and this reset manager bit depends on it ? Then swap patches
3 and 4 and you can wrap this function into the reset manager part, no?

uart_com_port() is in patch 10 (misc arria10). I can't swap reset
arria 10 and misc arria 10 because misc arria 10 got dependency on
reset arria 10 patch too..:(
What I mean is add a new patch just before this SPL patch to add reset_uart().

Well uh, I have to admit I'm a bit lost in the series and the
discussion. Is there any chance you can make the series bisectable ?
That's what I'd like to see.

Convert Altera ddr driver to use Kconfig method. Enable ALTERA_SDRAM
by default if it is on Gen5 target. Arria 10 will have different driver.

The existing DDR driver is for Gen5 only. We will have new DDR driver
for Arria 10 in later patchset.

Can you please include me on this patchset? I'd like to help with the

I have to wonder, will the A10 SoCDK be usable with mainline U-Boot with
just this patchset or is something else missing, like ie. the
DDR driver ?

We want to get the basic upstream first and then will submit the
patchset for DDR and other components after this.

Do you have the full patchset, which can be used to boot Arria10 SoCDK,
available somewhere ? I would like to know how the pieces fit together.

Tien Foong is working on the sub sequence patchset, eg: for FPGA
manager and DDR.
He already got these 2 drivers, but still trying to get it boot to
U-boot stage with mainline U-boot.
We can send to you if you want take a look.
Thanks.
