This GPIO driver is common to SoCs that have in-order ARM cores
(BCM2835) as well as superscalar (BCM2836-7) and speculative
out-of-order cores (BCM2711).
For BCM2837 and BCM2711, the processor can dual-issue stores and
is free to merge writes to peripheral memory for pages mapped
MT_NORMAL_NC, which is the default provided by /dev/[gpio]mem.
This can cause glitches (or missing edges) on GPIO pins when
toggled with no delay, as pipelined writes to the same address
can get arbitrarily squelched.
To prevent this happening, make sure the preceding write ops are
flushed outside the shareable domain by using a memory barrier.

When we debug a target that works as a USB device, halting
the target causes the USB communication with the USB host to
become unresponsive. The host will try to reconnect/reset/setup
the unresponsive device during which communication with other
devices on the same USB bus can get stalled for several seconds.
If the JTAG adapter is on the same bus, we need to make sure
openOCD will wait for packets at least as long as the host USB
stack. Otherwise the USB stack might deliver a valid packet, but
openOCD would ignore it due to the timeout. The xHCI spec uses 5
sec timeouts, so let's use that in openOCD with some margin.
Use this value in all libusb calls. HID API might have a libusb
backend and would probably be victim to the same bug, so it
should use this timeout, too.
