Commit 3c0659b "ARM: Avoid compiler optimization for readb, writeb
and friends." introduced I/O accessors with memory barriers.
Unfortunately the new write*() accessors introduced a bug:
The problem is that the argument "v" gets evaluated twice. This
breaks code like used here (from "drivers/net/dnet.c"):
for (i = 0; i < wrsz; i++)
writel(*bufp++, &dnet->regs->TX_DATA_FIFO);
Use auxiliary variables to avoid such problems.

These variables are only used in case CONFIG_SYS_NO_FLASH is NOT set:
struct mtd_device *dev;
struct part_info *part;
u8 dev_type, dev_num, pnum;

Add waiting for receiving Ethernet gadget state on the Windows host
side before dropping pullup, but keep it for debug.

Port USB gadget RNDIS protocol support from linux-2.6.26
(.27 gadget stack actually has composite drivers).

Disconnecting USB gadget with pending interrupt may cause its wrong
handling in the next time when interface will be started again
(especially actual for RNDIS). This interrupt may force the gadget
to queue unexpected response before setup stage.
Despite the fact that such interrupt handled after dropped pullup
also may add pending response, this will not bring to any issues due to
usb_ep_disable (which clears the queue) called on gadget unregistering.

This adds support for using USB Ethernet dongles in host mode. This is just
the framework - drivers will come later. A new config option called
CONFIG_USB_HOST_ETHER can be defined in board config files to switch this
on.
The was originally written by NVIDIA and was cleaned up for release by the
Chromium authors.

Changed both to use a common timeout for URB submission, since they were using
different values and EHCI's was too short.
Also fixed EHCI to actually check if urb submission succeeded, rather than
silently continuing into the weeds.

Fix the problem which cannot build the U-boot, if we only set
the CONFIG_ENV_IS_IN_SPI_FLASH.

The unzip command did not provide a way for the caller to get any
information about the uncompressed size. To make it better usable in
scripts, we now store the uncompressed size in the `filesize'
variable, like we do when for example loading a file over the network
or when reading it from a file system. Following that analogy, it is
only consequent to also print the size.

The implementation of the string compare function of the "itest"
command was weird, as only the length of the shortest argument was
included in the compare, with the result that something like
"itest.s abd == abddef" would return TRUE. Fix this.

early_board_init has been skipped to avoid SDRAM corruption in the case
that a fully relocatable image has been loaded into SDRAM and is being
executed from SDRAM. x86 is being aligned with other architectures (ARM
and PPC in particlar) and will be using Cache-As-RAM to run a C
environment from Flash (or SRAM if you have some). early_board_init may
be needed to assist in the setup of Cache-As-RAM and the early C
environment
