Move ALLOC_CACHE_ALIGN_BUFFER() to the new memalign.h header

2015-09-11T21:15:20+00:00

Now that we have a new header file for cache-aligned allocation, we should
move the stack-based allocation macro there also.

dm: usb: fix USB Ethernet without CONFIG_DM_ETH regression

2015-08-06T02:57:50+00:00

The following commit enforces CONFIG_DM_ETH for USB Ethernet which
breaks any board using CONFIG_USB_HOST_ETHER without CONFIG_DM_ETH
which this patch fixes.

commit 69559093f6173dcfcb041df0995063bdbd07d49b
dm: usb: Avoid using USB ethernet with CONFIG_DM_USB and no DM_ETH

Tested on Colibri T20/T30 as well as Apalis T30 with
CONFIG_USB_HOST_ETHER and CONFIG_USB_ETHER_ASIX enabled and a LevelOne
USB-0301 ASIX AX88772 dongle.

dm: usb: eth: Support driver model with USB Ethernet

2015-07-21T23:39:40+00:00

At present USB Ethernet does not work with CONFIG_DM_ETH. Add driver model
support to this feature, so that it can work alongside other Ethernet
devices with driver model.

It was found that quite a bit of code is common in most of the USB Ethernet
drivers. Add this code to the common layer to reduce the amount of duplicate
code needed in USB Ethernet drivers when CONFIG_DM_ETH is used.

dm: usb: Avoid using USB ethernet with CONFIG_DM_USB and no DM_ETH

2015-07-21T23:39:39+00:00

If driver model is used for Ethernet then USB Ethernet does not build. This
can be made to work with driver model is used for USB also. Add #ifdef logic
to make this clear when building.

dm: usb: Do not assume that first child is always a hub

2015-07-21T23:39:36+00:00

On some single port (otg) controllers there is no emulated root hub, so
the first child (if any) may be one of: UCLASS_MASS_STORAGE,
UCLASS_USB_DEV_GENERIC or UCLASS_USB_HUB.

All three of these (and in the future others) are suitable for our
purposes, remove the check for the device being a hub, and add a check to
deal with the fact that there may be no child-dev.

dm: usb: Fix "usb tree" output

2015-07-21T23:39:35+00:00

last_child was abused by the old usb code to first store 1 if the
usb_device was not the root of the usb tree, and then later on re-used
to store whether or not the usb_device is actually the last child.

The dm-usb code was always setting it to actually reflect the last-child
status which is wrong for the last child leading to output like this:

USB device tree:
  1  Hub (12 Mb/s, 100mA)
  |  ALCOR USB Hub 2.0
  |
  | 2  Mass Storage (12 Mb/s, 100mA)
  |    USB Flash Disk 4C0E960F
  |
  +-3  Human Interface (1.5 Mb/s, 100mA)
       SINO WEALTH USB Composite Device

Instead of this:

USB device tree:
  1  Hub (12 Mb/s, 100mA)
  |  ALCOR USB Hub 2.0
  |
  +-2  Mass Storage (12 Mb/s, 100mA)
  |    USB Flash Disk 4C0E960F
  |
  +-3  Human Interface (1.5 Mb/s, 100mA)
       SINO WEALTH USB Composite Device

This commit fixes this by first checking that the device is not root,
and then setting last_child. This commit also updates the old code to not
abuse the last_child variable to store the root check result.

dm: usb: Convert 'usb' command to support driver model

2015-04-18T17:11:20+00:00

Adjust this command to work with the new driver model uclass. It needs to
iterate through multiple independent controllers to find hubs, and work
through their children recursively in a different way. Otherwise the
functionality is much the same.

dm: usb: Adjust usb command to prepare for driver model

Use 'udev' instead of 'dev' in a few places, reserving 'dev' for driver
model's struct udevice. Also adjust the code in a few minor ways to make
it easier to plumb in driver model.

USB: make "usb start" start usb only once

2015-01-18T11:31:35+00:00

Currently we've this magic in include/config_distro_bootcmd.h to avoid
scanning the usb bus multiple times.

And it does not work when also using an usb keyboard because then the
preboot command has already scanned the bus, so we're still scanning it
twice.

This commit makes "usb start" only start usb if it is no already started,
allowing us to remove all the magic for it from include/config_distro_bootcmd.h
and just call it unconditionally.

This also causes "usb start" and "usb reset" to actually do what their
different names suggest, rather then both of them doing exactly the same.

usb: kbd: Allow "usb reset" to continue when an usb kbd is used

Use the new force parameter to make the stdio_deregister succeed, replacing
stdin with a nulldev, and assume that the usb keyboard will come back after
the reset.
