usb: finally get rid of USE_ROCKBOX_USB in Sansa bootloader, use bootloader usb

2015-01-08T21:30:22+00:00

For some reason, the bootloader and config files didn't define
HAVE_BOOTLOADER_USB_MODE, also remove the special cases in usb.c which they
implied.

Clarify usb_powered() and fix some code.

2015-01-08T15:45:32+00:00

Either by mistake or because its meaning changed, usb_powered() doesn't mean
what the name suggest, so clarify its meaning by renaming it to usb_powered_only.
So use of usb_powered() are replaced by usb_inserted() when it makes more sense.

Get rid of USE_ROCKBOX_USB

2015-01-08T15:07:12+00:00

Except for unfinished or experimental ports, it isthe case that
USE_ROCKBOX_USB and HAVE_USBSTACK are both defined or both undefined.
Furthermore, it is a leftover of some early developments on the USB stack and
doesn't make sense anymore.

USB: Detect charging-only mode upon cable insert, not host detect.

2013-05-22T06:28:31+00:00

Letting go of the button before the host is detected allows storage mode
to be entered even though a button was down when plugging. Sometimes the
host would try several times and the button would have to be held down
for several seconds to avoid a storage connection.

The adjustment wasn't made when switching to setup request host
detection.

usb: add support for hardware handled SET ADDR/CONFIG

2012-12-07T12:37:26+00:00

Some USB controllers like the one of the Rockchip 27xx handle some
requests in pure hardware. This is especially a problem for two
of them:
- SET ADDR which is used by our core to track the DEFAULT/ADDRESS
  state and is required for the drivers to work properly
- SET CONFIG which is used by our core to initialise the drivers
  by calling init_connection()
In these cases we need a way to notify the core that such requests
happened.
We do this by exporting two functions which directly notify the
core about these requests and perform the necessary init steps
required without doing the actual USB transfers. Special care is
needed because these functions could be called from an interrupt
handler. For this reason we still use the usb_queue and introduce
new IDs so that they are processed in order and safely.

No functional change is intended, both in the usbstack and on
targets without such quirks.

Undo f695681 (r30433). USB hardware must be initialized first.

This fixes flash/ MMC access on the Ondios when booting from ROM.
Add a comment what to pay attention for in the target specific
usb_init_device().
