[PATCH v4 0/3] Reliability improvements for Microchip MPF FPGA manager

From: Ivan Bornyakov
Date: Thu Dec 29 2022 - 05:49:32 EST


A couple of reliability improvements for Microchip Polarfire FPGA
manager:
* move SPI I/O buffers out of stack
* rewrite status polling routine in a time measurable way

Also improve mpf_ops_write() code readability by separating single data
frame writing routine.

ChangeLog:
v1:
[https://lore.kernel.org/linux-fpga/20221223123854.8023-1-i.bornyakov@xxxxxxxxxxx/]
v2:
* split into 3 distinct patches
[https://lore.kernel.org/linux-fpga/20221226142326.8111-1-i.bornyakov@xxxxxxxxxxx/]
v3:
* fix polling stop condition in mpf_poll_status() as Ilpo suggested.
