u-boot.git/drivers/usb, branch v2008.10

Make usb-stop() safe to call multiple times in a row.

2008-09-09T14:59:25+00:00

A recent commit (936897d4d1365452bbbdf8430db5e7769ef08d38)
enabled the usb_stop() command in common/cmd_bootm.c which was
not enabled for some time, because no board did actually set the
CFG_CMD_USB flag. So, now the usb_stop() is executed before
loading the linux kernel.

However, the usb_ohci driver hangs up (at least on AT91SAM) if the
driver is stopped twice (e.g. the peripheral clock is stopped on AT91).
If some other piece of code calls usb_stop() before the bootm command,
this command will hangup the system during boot.
(usb start and stop is typically used while booting from usb memory stick)

But, stopping the usb stack twice is useless anyway, and a flag already
existed that kept track on the usb_init()/usb_stop() calls.
So, we now check if the usb stack is really started before we stop it.

This problem is now fixed in both the upper as low-level layer.

USB EHCI: reset root hub

2008-09-05T23:24:55+00:00

Some of multi-function USB controllers (e.g. ISP1562) allow root hub
resetting only via EHCI registers. So, this patch adds the
corresponding kind of reset to OHCI's hc_reset() if the newly
introduced CONFIG_PCI_EHCI_DEVNO option is set (e.g. for Socrates
board).

USB: Add support for OHCI controller on S3C6400

2008-08-30T22:39:46+00:00

Notice: USB on S3C6400 currently works _only_ with switched off MMU. One could
try to enable the MMU, but map addresses 1-to-1, and disable data cache, then
it should work too and we could still profit from instruction cache.

Fix compile error related to r8a66597-hcd & usb

2008-08-11T22:00:03+00:00

When building the 8544DS board we get this error:

In file included from r8a66597-hcd.c:22:
u-boot/include/usb.h:190:2: error: #error USB Lowlevel not defined
make[1]: *** [r8a66597-hcd.o] Error 1

The cleanest fix is to only build r8a66597-hcd.c if CONFIG_USB_R8A66597_HCD
is set.
