>From source code comments:
"x0: 0 flush & invalidate, 1 invalidate only"
Current value 0xffff can make invalidate work, since we only judge whether
input value is 0 or not, see following code:
"
tbz w1, #0, 1f
dc isw, x9
b 2f
1: dc cisw, x9 /* clean & invalidate by set/way */
2: subs x6, x6, #1 /* decrement the way */
"
Later we may add "2 clean only" support. So following the comments,
correct value from 0xffff to 1.

The current comments need a bit of tweaking since we now support stack
and global_data relocation in SPL. Also add a reference to the README.
For AArch64 this is not implemented, so leave a TODO for this.

usb: gadget: remove incorrect __init/__exit annotations
A recent change introduced a link error for the composite
printer gadget driver:
`printer_unbind' referenced in section `.ref.data' of drivers/built-in.o: defined in discarded section `.exit.text' of drivers/built-in.o
Evidently the unbind function should not be marked __exit here,
because it is called through a callback pointer that is not necessarily
discarded, __composite_unbind() is indeed called from the error path of
composite_bind(), which can never work for a built-in driver.
Looking at the surrounding code, I found the same problem in all other
composite gadget drivers in both the bind and unbind functions, as
well as the udc platform driver 'remove' functions. Those will break
if anyone uses the 'unbind' sysfs attribute to detach a device from a
built-in driver.
This patch removes the incorrect annotations from all the gadget
drivers.

If we convert to use driver model pci on quark, we will encounter
some chicken and egg problems like below:
- To enable PCIe root ports, we need program some registers on the
message bus via pci bus. With driver model, the first time to
access pci bus, the pci enumeration process will be triggered.
But without first enabling PCIe root ports, pci enumeration
just hangs when scanning PCIe root ports.
- Similar situation happens when trying to access GPIO from the
PCIe enabling codes, as GPIO requires its block base address
to be assigned via a pci configuration register in the bridge.
To avoid such dilemma, replace all pci calls in the quark codes
to use the local version which does not go through driver model.

Intel Quark SoC has a low end x86 processor with only 400MHz
frequency. Currently it takes about 15 seconds for U-Boot to
boot to shell and the most time consuming part is with MRC,
which is about 12 seconds. MRC programs lots of registers on
the SoC internal message bus indirectly accessed via pci bus.
To speed up the boot, create an optimized version of pci config
read/write dword routines which directly operate on PCI I/O ports.
These two routines are inlined to provide better performance too.
Now it only takes about 3 seconds to finish MRC, which is really
fast (4 times faster than before).

At present, until a PCI bus is probed, it cannot be found by its sequence
number unless it has an alias. This is the same with any device.
However with PCI this is more annoying than usual, since bus 0 is always the
same device.
Add a function that tries a little harder to locate PCI bus 0. This means
that PCI enumeration will happen automatically on the first access.

At present buildman can compare configurations between commits but the
feature is less useful than it could be. There is no summary by architecture
and changes are not reported on a per-board basis.
Correct these deficiencies so that it is possible to see exactly what is
changing for any number of boards.
Note that 'buildman -b <branch> -C' is recommended for any build where you
will be comparing configuration. Without -C the correct configuration will
not be reported since changes will often not be picked up.

This reverts commit 19b4a33698.
Since that commit, patman generates useless patches for file removal;
"git format -D" prints only the header but not the diff when deleting
files, and "git am" always refuses such patches.
The following is the quotation from "man git-format-patch":
-D, --irreversible-delete
Omit the preimage for deletes, i.e. print only the header but
not the diff between the preimage and /dev/null. The resulting
patch is not meant to be applied with patch nor git apply; this
is solely for people who want to just concentrate on reviewing
the text after the change. In addition, the output obviously
lack enough information to apply such a patch in reverse, even
manually, hence the name of the option.

When an EHCI device is registered in device mode, the HW isn't actually
initialized at all, and hence isn't left in a running state. Consequently,
when the device is deregistered, ehci_shutdown() will fail, since the HW
bits it expects to see set in response to its shutdown requests will not
be sent, and the message "EHCI failed to shut down host controller." will
be printed.
Fix ehci-hcd.c to remember whether the device was registered in host or
device mode, and only call ehci_shutdown() for host mode registrations.
