I will drop the xhci patchset and hope to get a fixed one from him.
The latest branch content (0184c6fb34b4 "usb: dwc2: Align size of invalidating dcache before starting DMA") passes the tests.
My tests shows that 'ut dm usb_flash' fails, and should have failed for quite a long time.

The latest u-boot-usb master branch breaks the following unit tests for the sandbox target (as run by test/py):
8 failed ... test_ut[ut_dm_blk_usb] ... test_ut[ut_dm_usb_flash] ... test_ut[ut_dm_usb_keyb] ... test_ut[ut_dm_usb_multi] ... test_ut[ut_dm_usb_remove] ... test_ut[ut_dm_usb_tree] ... test_ut[ut_dm_usb_tree_remove] ... test_ut[ut_dm_usb_tree_reorder]
I've fixed all test failures except 'ut dm usb_flash'.
Looks I was jumping to conclusions. Previously I was just marking sandbox as an exception in the 'usb_stop', and all tests were passed. But I feel that's inconsistent. Now with a proper fix for sandbox, the 'usb remove' test no longer passed because I was trying to delete the "/usb@1/hub/hub-emul/flash-stick@1" node from device tree but a follow-up 'usb_init()' will fail. I am new to the sandbox emulator and still investigating this. Any hints?
Please check my WIP patch @ http://git.denx.de/?p=u-boot/u-boot-x86.git;a=commitdiff;h=e8481c91c295027f7... for fixing sandbox 'usb remove' issues.
Below are my test logs on Sandbox:
=> usb start starting USB... USB0: scanning bus 1 for devices... 5 USB Device(s) found scanning usb for storage devices... 3 Storage Device(s) found => usb stop stopping USB.. => fdt addr -c The address of the fdt is 0x5986ba0 => fdt addr 0x5986ba0 => fdt rm "/usb@1/hub/hub-emul/flash-stick@1" => usb start starting USB... USB0: scanning bus 1 for devices... USB device not accepting new address (error=80000000) failed, error -2 scanning usb for storage devices... 0 Storage Device(s) found
Any hints?
Any suggestions would be appreciated. I don't think I was the first one who wanted to test deleting some nodes from the device tree, and redo the fdt scan stuff.
