41b1f0ac2e USB: Document the QH and qTD antics in EHCI-HCD
The construction of QH and qTD lists in ehci_submit_async() call is cryptic
business, add at least a bit of comments so if someone is reading it, he can at
least reference the intel ehci manual (ehci-r10.pdf).

b8adb12095 USB: Drop cache flush bloat in EHCI-HCD
Discard the creepy cache flushing mechanisms in ehci-hcd.c and replace them with
more straightforward flushing. In the new approach, the flushing takes place
directly in ehci_submit_async() call instead of going through the QH list and
flushing all members and buffers. This discards a lot of weird bit operations
on the members of QH and qTD structures.

NOTE: Certainly, this flushes even qTDs which are possibly unused in some
transactions, though the overhead of the previous code was much higher than is
the overhead of flushing two more cache lines (which most probably aren't even
cached).

de98e8b22a USB: Drop ehci_alloc/ehci_free in ehci-hcd
These two functions were called only from ehci_submit_async(), therefore
dissolve them as part of ehci_submit_async() to get rid of all those static

f57661394a USB: Align buffers at cacheline
This avoids cache-alignment warnings shown in console
when a usb command is entered.

Whenever X bytes of unaligned buffer is invalidated, arm core
invalidates X + Y bytes as per the cache line size and throws
these warnings.

66cf64107b usb: use noinline define
Building usb for Blackfin boards fails as we get linux/compiler.h
included which expands the "noinline" inside of the attribute and
we get attribute(attribute(noinline)).

f50bf50d7f Improve MAKEALL parallel builds
The patch that added parallel builds broke MAKEALL -l, so this
fixes that. At the same time, it improves the termination so
that it shuts down the build threads if you cancel the build.
Lastly, it removes a bunch of debug code.

bb1c01eaf6 Remove extra boards from LIST_ixp
pdnb3 and scpu are explicitly on LIST_ixp, even though they are
also specified in boards.cfg as having cpu ixp. This means that
they will be built twice when doing ./MAKEALL ixp, or ./MAKEALL arm.

This was pointless before, but actually breaks things if you launch
both builds at the same time, as they overwrite each other.

f588bb034d Allow for parallel builds and saved output
The MAKEALL script cleverly runs make with the appropriate options
to use all of the cores on the system, but your average U-Boot build
can't make much use of more than a few cores.  If you happen to have
a many-core server, your builds will leave most of the system idle.

In order to make full use of such a system, we need to build multiple
targets in parallel, and this requires directing make output into
multiple directories. We add a BUILD_NBUILDS variable, which allows
users to specify how many builds to run in parallel.
When BUILD_NBUILDS is set greater than 1, we redefine BUILD_DIR for
each build to be ${BUILD_DIR}/${target}. Also, we make "./build" the
default BUILD_DIR when BUILD_NBUILDS is greater than 1.

MAKEALL now tracks which builds are still running, and when one
finishes, it starts a new build.

Once each build finishes, we run "make tidy" on its directory, to reduce
the footprint.

As a result, we are left with a build directory with all of the built
targets still there for use, which means anyone who wanted to use
MAKEALL as part of a test harness can now do so.

5d065c3e10 powerpc/85xx: don't display address map size (32-bit vs. 36-bit) during boot
Most 85xx boards can be built as a 32-bit or a 36-bit.  Current code sometimes
displays which of these is actually built, but it's inconsistent.  This is
especially problematic since the "default" build for a given 85xx board can
be either one, so if you don't see a message, you can't always know which
size is being used.  Not only that, but each board includes code that displays
the message, so there is duplication.

The 'bdinfo' command has been updated to display this information, so
we don't need to display it at boot time.  The board-specific code is
deleted.

right time by SRIO interface.

Master needs to:
	1. Set outbound SRIO windows in order to configure slave's registers
	   for the core's releasing.
	2. Check the SRIO port status when release slave core, if no errors,
	   will implement the process of the slave core's releasing.
Slave needs to:
	1. Set all the cores in holdoff by RCW.
	2. Be powered on before master's boot.

292dc6c501 powerpc/corenet_ds: Slave module for boot from SRIO
For the powerpc processors with SRIO interface, boot location can be configured
from SRIO1 or SRIO2 by RCW. The processor booting from SRIO can do without flash
for u-boot image. The image can be fetched from another processor's memory
space by SRIO link connected between them.

The processor boots from SRIO is slave, the processor boots from normal flash
memory space and can help slave to boot from its memory space is master.
They are different environments and requirements:

master:
	1. NOR flash for its own u-boot image, ucode and ENV space.
	2. Slave's u-boot image in master NOR flash.
	3. Normally boot from local NOR flash.
	4. Configure SRIO switch system if needed.
slave:
	1. Just has EEPROM for RCW. No flash for u-boot image, ucode and ENV.
	2. Boot location should be set to SRIO1 or SRIO2 by RCW.
	3. RCW should configure the SerDes, SRIO interfaces correctly.
	4. Slave must be powered on after master's boot.
	5. Must define CONFIG_SYS_QE_FMAN_FW_IN_REMOTE because of no ucode
	   locally.

For the slave module, need to finish these processes:
	1. Set the boot location to SRIO1 or SRIO2 by RCW.
    2. Set a specific TLB entry for the boot process.
	3. Set a LAW entry with the TargetID SRIO1 or SRIO2 for the boot.
	4. Slave's u-boot image should be generated specifically by
	   make xxxx_SRIOBOOT_SLAVE_config.
	   This will set SYS_TEXT_BASE=0xFFF80000 and other configurations.

	4. Slave must be powered on after master's boot.

For the master module, need to finish these processes:
	1. Initialize the SRIO port and address space.
	2. Set inbound SRIO windows covered slave's u-boot image stored in
	   master's NOR flash.
	3. Master's u-boot image should be generated specifically by
	   make xxxx_SRIOBOOT_MASTER_config
	4. Master must boot first, and then slave can be powered on.

This document describes the implementation of the boot from SRIO,
includes the introduction of envionment, an example based on P4080DS
platform, an example of the slave's RCW, and the description about
how to use this feature.
