Adds support for loading U-Boot from UART using YMODEM protocol.
If YMODEM support is enabled in SPL and the romcode indicates
that SPL loaded via UART then SPL will wait for start of a
YMODEM transfer via the console port.

The SD loader binary is now downloadable at
https://wiki.linaro.org/Boards/MX6QSabreLite
under a open-source 3-clause BSD license. Update the README
for this.
The discussion shows that it's hard to change the hardware
regarding the default SPI NOR boot of the SabreLite boards.
I.e. this will stay the default boot. Therefore remove the
'early version of' statement.

This reverts commit 295d3942b8.
It turns that this really doesn't work very nicely. Instead we should
have a pre-console panic function so that we know that further execution
is impossible and we don't need to worry about trampling on UARTs, etc.

This patch fixes a few bugs in USB device controller driver.
The fixes are as follows
1. Adding error condition checks eg. NULL return
2. Endpoint other than endpoint 0 (control endpoint) are initialized
only if usb state machine reaches STATE_ADDRESSED or above
3. Zero length packet handling corrected
4. Dead code removed
5. Bulk out endpoint returns after servicing 1 interrupt and returns
back to service if more interrupts are pending

Add calls to bootstage before and after relocation, and just
before jumping to the OS.
The idea here is you can call bootstage_report() to get a report.
Additionally, if you define CONFIG_BOOTSTAGE_REPORT then a report is
printed automatically by U-Boot just before jumping to the kernel.

This inserts bootstage calls into tftp, usb start and bootm. We

This defines the basics of a new boot time measurement feature. This allows
logging of very accurate time measurements as the boot proceeds, by using
an available microsecond counter.
To enable the feature, define CONFIG_BOOTSTAGE in your board config file.
Also available is CONFIG_BOOTSTAGE_REPORT which will cause a report to be
printed just before handing off to the OS.
Most IDs are not named at this stage. For that I would first like to
renumber them all.
Timer summary in microseconds:

Define timer_get_boot_us() which returns the number of microseconds
since boot. If undefined then we use get_timer() * 1000.
We can fit this in a 32-bit register which keeps everyone happy on
the efficiency side. It will wrap around after about an hour. If we
are still looking at it after an hour then we had better not be
timing the boot.
