Add support to the FPGA manager for programming Lattice ECP5 FPGA over
slave SPI interface with .bit formatted uncompressed bitstream image.

Not sure if something is missed.

I was considering if a generic driver for lattice slave SPI sysCONFIG
interface could be introduced. From machxo2 & ecp5 Programming Usage
Guide, or others in this series, they basically use the same reconfigure
interface & protocol.

I only have HW with ECP5, can't vouch for the rest.

I understand your concern, but having separate drivers for the same IP on
different boards makes the maintaining harder.

We don't have to make everything fine, but start with machxo2 and ecp5
first. If the change affects machxo2, other people may help.

Thanks,

Hi, Yilun.

To clear things out, considering what Daniel said in
https://lore.kernel.org/linux-fpga/20220816074216.GA31706@homes.emlix.com/ (local)
you still don't want separate ECP5 driver, or this v6 is OK and review

I still perfer one sysCONFIG driver. If I understand right, the 2
reprogramming modes and the command sets are within the scope of
sysCONFIG spec. So they could be all supported in sysCONFIG driver, and
I assume some config option could be made to adapt different boards.

Thanks,
Yilun

continues?
