ARM: tegra: remove Whistler support

Whistler is an ancient Tegra 2 reference board. I may have been the only
person who ever used it with upstream software, and I've just recycled
the board hardware. Hence, it makes sense to remove support from software.

Manfred Schlaegl [Wed, 10 May 2017 13:41:32 +0000 (15:41 +0200)] 
ARM: fixed relocation using proper alignment

Using u-boot-2017.05 on i.MX6UL we ran into following problem:
Initially U-Boot could be started normally.
If we added one random command in configuration, the newly generated
image hung at startup (last output was DRAM:  256 MiB).

We tracked this down to a data abort within relocation (relocated_code).

relocated_code in arch/arm/lib/relocate.S copies 8 bytes per loop
iteration until the source pointer is equal to __image_copy_end.
In a good case __image_copy_end was aligned to 8 bytes, so the loop
stopped as suggested, but in an errornous case __image_copy_end was
not aligned to 8 bytes, so the loop ran out of bounds and caused a
data abort exception.

This patches solves the issue by aligning __image_copy_end to 8 byte
using the linker script related to arm.

I don't know if it's the correct way to solve this, so some review would
be very appreciated.

Most Chromebooks support chain-loading U-Boot but instructions are
somewhat scattered. Add a README to hold this information within the
U-Boot tree. Also add the standard developer keys to simplify the
instructions, since they are small.

For now this only supports nyan-big.
