usb: ci_udc: pre-allocate ep0 req
Allocate ep0's USB request object when the UDC driver is probed. This
solves a couple of issues in the current code:
a) A request object always exists for ep0. Prior to this patch, if setup
transactions arrived in an unexpected order, handle_setup() would need
to reply to a setup transaction before any ep0 usb_req was created.
This issue was introduced in commit 2813006fecda "usb: ci_udc: allow
multiple buffer allocs per ep."
b) handle_ep_complete no longer /has/ to queue the ep0 request again
after every single request completion. This is currently required, since
handle_setup() assumes it can find some request object in ep0's request
queue. This patch doesn't actually stop handle_ep_complete() from always
requeueing the request, but the next patch will.

For cm_t35.h, we already wait longer than the original MIN_POWER_ON_DELAY,
so this change is safe.
For gw_ventana.h, we will wait as long as the original MIN_POWER_ON_DELAY

usb: hub: fix power good delay timing
usb_hub_power_on() currently waits for the maximum of (a) the hub port's
power output to become good, (b) the max time the USB specification
allows a device to take to connect.
However, these two operations must occur in series rather than in
parallel. First, the power supply ramps up to the level required to
power the USB device, and then the device may take a certain amount of
time to connect (assert D+/D- pullups).
Related, the maximum time that a device has to assert pullups is 1s not
100ms.

Subject: [PATCH] net/designware: reorder struct dw_eth_dev to pack more
efficiently.
The {tx,rx}_mac_descrtable fields are aligned to ARCH_DMA_MINALIGN, which could
be 256 or even larger. That means there is a potentially huge hole in the
struct before those fields, so move them to the front where they are better
packed.
Moving them to the front also helps ensure that so long as dw_eth_dev is
properly aligned (which it is since "net/designware: ensure device private data
is DMA aligned.") the {tx,rx}_mac_descrtable will be too, or at least avoids
having to worry too much about compiler specifics.
The {r,t}xbuffs fields also need to be aligned. Previously this was done
implicitly because they immediately followed the descriptor tables. Make this
explicit and also move to the head of the struct.

It's "correct" in so far as it works (the boards.cfg config stuff

...I had thought that it was to support some other board which wasn't
being upstreamed right now, so eventually useful and harmless for now,
but I've just checked and it isn't actually used by any of the boards in

Add Board Revision for Wireless chip
Gumstix Overo COMs with board revision 0x4 use a different Wifi and
Bluetooth module: Wi2Wi's W2CBW0015. No other code changes are required
in u-boot---just handling of this particular board revision.

arm: omap3: Fix omap3_overo SPL boot hangup
Patch f33b9bd3
[arm: omap3: Enable clocks for peripherals only if they are used]
breaks SPL booting on Overo. Since some gpio inputs are
read to detect the board revision. But with this patch above, the
clocks to the GPIO subsystems are not enabled per default any more.
The GPIO banks need to be configured specifically now.
The linux kernel is at nand0,3 using the current layout, but is best
accessed through the partition label "linux". Since CONFIG_CMD_MTDPARTS is
defined the CONFIG_JFFS2 settings are unreferenced; use "setenv partition
rootfs" to set the default mtd partition for jffs2.

OMAP3: overo: add command support for mtd and ubi
The NAND linux partition format default was changed from jffs2 to ubi in 254973e6df0e48f1a72b67905185c774dcd9f394 but the corresponding commands were
not enabled.

omap4: allow the use of a plain text env file instead boot scripts
For production systems it is better to use script images since
they are protected by checksums and carry valuable information like
name and timestamp. Also, you can't validate the content passed to
env import.
But for development, it is easier to use the env import command and
plain text files instead of script-images.
Since both OMAP4 supported boards (Panda and TI SDP4430) are used
primarily for development, this patch allows U-Boot to load env var
from a text file in case that an boot.scr script-image is not present.
The variable uenvcmd (if existent) will be executed (using run) after
uEnv.txt was loaded. If uenvcmd doesn't exist the default boot sequence
will be started.

mmc: provide a select_hwpart implementation for get_device()
This enables specifying which eMMC HW partition to target for any U-Boot
command that uses the generic get_partition() function to parse its
command-line arguments.

disk: support devices with HW partitions
Some device types (e.g. eMMC) have hardware-level partitions (for eMMC,
separate boot and user data partitions). This change allows the user to
specify the HW partition they wish to access when passing a device ID to
U-Boot Commands such as part, ls, load, ums, etc.
The syntax allows an optional ".$hwpartid" to be appended to the device
name string for those commands.
Existing syntax, for MMC device 0, default HW partition ID, SW partition
ID 1:
ls mmc 0:1 /
New syntax, for MMC device 0, HW partition ID 1 (boot0), SW partition
ID 2:
ls mmc 0.1:2 /
For my purposes, this is most useful for the ums (USB mass storage
gadget) command, but there's no reason not to allow the new syntax
globally.
This patch adds the core support infra-structure. The next patch will
provide the implementation for MMC.
