Hi,
Yes.. as do the stX_pci_dma() helpers. They assume LE, rather than
having two variants, because PCI is an LE spec, and all normal PCI
devices work in LE.
IMO, not really. PCI devices do DMA any way they like. LE is
probably more common because both ARM and x86 processors are LE.
Also having _le_ in the function name makes explicitly clear that the
functions read/write little endian values and byteswaps if needed, which
makes the code more readable. I'd suggest to add it even if there is no
need for a _be_ companion as devices needing that are rare.
cheers,
Gerd
