* Make usb-stop() safe to call multiple times in a row.Remy Bohmer2008-09-09-4/+9
| | | | | | | | | | | | | | | | | | | | | | | 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.Wolfgang Denk2008-05-21-3/+3
| | | | | | | | | | | 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. Signed-off-by: Wolfgang Denk <wd@denx.de>

| | | | | | | | 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. Signed-off-by: Stefan Roese <sr@denx.de>

| | | | | | | | | | | | | | 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) Signed-off-by: Jon Loeliger <jdl@freescale.com>

| | | | | | | | A new, Windows compatible init sequence was also backported from Linux 2.6, but disabled with #undef NEW_INIT_SEQ as it wouldn't change the behaviour of the memopry sticks we tested. Maybe it's not relevant for mass storage devices. For recerence, see file common/usb.c, function usb_new_device(), section #ifdef NEW_INIT_SEQ.
