The RDY bit indicates that a transfer is complete. This needs to be
cleared by SW before every single HW transaction, rather than only
at the start of each SW transaction (those being made up of n HW
transactions).
It seems that earlier HW may have cleared this bit autonomously when
starting a new transfer, and hence this code was not needed in practice.
However, this is generally a good idea in all cases. In Tegra124, the
HW behaviour appears to have changed, and SW must explicitly clear this
bit. Otherwise, SW will believe that transfers have completed when they
have not, and may e.g. read stale data from the RX FIFO.

[swarren, rewrote commit description, unified duplicate RDY clearing code
and moved it right before the start of the HW transaction, unconditionally
exit loop after reading RX data, rather than checking if TX FIFO is empty,
since it is guaranteed to be]

Commit fea25720 renamed arch/i386 to arch/x86.
But it missed to modify examples/standalone/Makefile.
Since then, examples/standalone/82559_eeprom has
never compiled and nobody has noticed that.
After some discussion on ML, we agreed to delete this example.

We have some scripts imported from Linux Kernel:
setlocalversion, checkstack.pl, checkpatch.pl, cleanpatch
They are located under tools/ directory in U-Boot now.
But they were originally located under scripts/ directory
in Linux Kernel.
This commit moves them to the original location.
It is true that binutils-version.sh and dtc-version.sh
do not originate in Linux Kernel, but they should
be moved by analogy to gcc-version.sh.

If U-Boot build with DEBUG enabled/defined the first call of "debug"
function (that dumps data to any available console) will happen before
zeroing of initial "gd" in init call "zero_global_data" in
"init_sequence_f".
And if stack was not filled with zeros chances are high that
"gd->have_console" won't be 0. In its turn it will cause attempt to
output things to non-initialized yet serial console.
So for safety and predictability we set "gd->have_console = 0".

Commit 8dfafdde88eb ("Introduce common timer functions") created a
common definition of usec_to_tick() which had a couple problems:
static unsigned long long usec_to_tick(unsigned long usec)
{
uint64_t tick = usec * get_tbclk();
That likely overflows.
usec *= get_tbclk();
That was an attempt to fix it by performing the multiply after the
promotion of usec to 64-bit, but was applied to the wrong variable,
which was never used.
This patch fixes these issues. A user-visible symptom of the problem was
the e.g. "dhcp zImage" using an ASIX USB Ethernet dongle would print:
Waiting for Ethernet connection... unable to connect.
... with no delay before "unable to connect". There are likely other
symptoms.

Some editors such as Emacs can highlight source files.
But their parser algorithm is not perfect.
If you use one double-quotation alone, some editor cannot
handle it nicely and mark source lines as a string by mistake.
It is preferable to use two double-quotations as a pair.

Given a multi-file image created through the mkimage's -d option:
$ mkimage -A x86 -O linux -T multi -n x86 -d vmlinuz:initrd.img:System.map \
multi.img
Image Name: x86
Created: Thu Jul 25 10:29:13 2013
Image Type: Intel x86 Linux Multi-File Image (gzip compressed)
Data Size: 13722956 Bytes = 13401.32 kB = 13.09 MB
Load Address: 00000000
Entry Point: 00000000
Contents:
Image 0: 4040128 Bytes = 3945.44 kB = 3.85 MB
Image 1: 7991719 Bytes = 7804.41 kB = 7.62 MB
Image 2: 1691092 Bytes = 1651.46 kB = 1.61 MB
It is possible to perform the innverse operation -- extracting any file from
the image -- by using the dumpimage's -i option:
$ dumpimage -i multi.img -p 2 System.map
Although it's feasible to retrieve "data files" from image through scripting,
the requirement to embed tools such 'dd', 'awk' and 'sed' for this sole purpose
is cumbersome and unreliable -- once you must keep track of file sizes inside
the image. Furthermore, extracting data files using "dumpimage" tool is faster
than through scripting.

In order to avoid duplicating code and keep only one point of modification,
the functions, structs and defines useful for "dumpimage" were moved from
"mkimage" to a common module called "imagetool".
This modification also weakens the coupling between image types (FIT, IMX, MXS,
and so on) and image tools (mkimage and dumpimage). Any tool may initialize the
"imagetool" through register_image_tool() function, while the image types
register themselves within an image tool using the register_image_type()
function:
+---------------+
+------| fit_image |
+--------------+ +-----------+ | +---------------+
| mkimage |--------> | | <-----+
+--------------+ | | +---------------+
| imagetool | <------------| imximage |
+--------------+ | | +---------------+
| dumpimage |--------> | | <-----+
+--------------+ +-----------+ | +---------------+
+------| default_image |
+---------------+
register_image_tool() register_image_type()
Also, the struct "mkimage_params" was renamed to "image_tool_params" to make
clear its general purpose.
