For 16kB buffer upload time is reduced from ~90ms to ~80ms (I tested

That does seem worthwhile. Is that just a single transfer in isolation?
I gave you summary time when firmware is transferred via 22x16kB blocks.
Each transfer was isolated.
amba-pl80 uses virtual DMA channels support so driver won't occupy
all the time physical channel. pl330 driver don't use such framework
but It will be very hard to occupy all channels at the same time. If
I'm wrong please correct me.
OK.
