u-boot.git/common/usb.c, 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.

Big white-space cleanup.

2008-05-20T22:14:08+00:00

This commit gets rid of a huge amount of silly white-space issues.
Especially, all sequences of SPACEs followed by TAB characters get
removed (unless they appear in print statements).

Also remove all embedded "vim:" and "vi:" statements which hide
indentation problems.

ppc4xx: Rename 405gp_pci to 4xx_pci since its used on all 4xx platforms

2007-10-31T20:20:49+00:00

These files were introduced with the IBM 405GP but are currently used on all
4xx PPC platforms. So the name doesn't match the content anymore. This patch
renames the files to 4xx_pci.c/h.

common/ non-cmd: Augment CONFIG_COMMANDS tests with defined(CONFIG_CMD_*).

2007-07-03T22:23:10+00:00

This is a compatibility step that allows both the older form
and the new form to co-exist for a while until the older can
be removed entirely.

All transformations are of the form:
Before:
    #if (CONFIG_COMMANDS & CFG_CMD_AUTOSCRIPT)
After:
    #if (CONFIG_COMMANDS & CFG_CMD_AUTOSCRIPT) || defined(CONFIG_CMD_AUTOSCRIPT)
