If we use hardware with very small RAM (let's consider just a couple of hundreds of kB but not megabytes) it is not super convenient to lose 64kB for statically allocated bufer which most probably won't be used as big as it is. Typically we'll have much shorter data packages to excahnge and in the worst case longer packets will be split on separate transactions. For those corner-cases user will be able to set his buffer size of choice via USB_DWC2_BUFFER_SIZE option in menuconfig. By default we'll use 64 kB as it was hard-coeded before so existing users shouldn't be affected at all. Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com> Cc: Marek Vasut <marex@denx.de>

The Enhanced Host Controller Interface (EHCI) is standard for USB 2.0

"high speed" (480 Mbit/sec, 60 Mbyte/sec) host controller hardware.
|
|
If your USB host controller supports USB 2.0, you will likely want to
|
|
configure this Host Controller Driver.
|
|
|
|
EHCI controllers are packaged with "companion" host controllers (OHCI
|
|
or UHCI) to handle USB 1.1 devices connected to root hub ports. Ports
|
|
will connect to EHCI if the device is high speed, otherwise they
|
|
connect to a companion controller. If you configure EHCI, you should
|
|
probably configure the OHCI (for NEC and some other vendors) USB Host
|
|
Controller Driver or UHCI (for Via motherboards) Host Controller
|
|
Driver too.

The Open Host Controller Interface (OHCI) is a standard for accessing

USB 1.1 host controller hardware. It does more in hardware than Intel's

UHCI specification. If your USB host controller follows the OHCI spec,

say Y. On most non-x86 systems, and on x86 hardware that's not using a
|
|
USB controller from Intel or VIA, this is appropriate. If your host
|
|
controller doesn't use PCI, this is probably appropriate. For a PCI
|
|
based system where you're not sure, the "lspci -v" entry will list the
|
|
right "prog-if" for your USB controller(s): EHCI, OHCI, or UHCI.
