juno: Fix bug in plat_get_my_entrypoint
plat_get_my_entrypoint was branching to juno_do_reset_to_aarch_32_state,
which is not supposed to return, and in case of returning it implemented
an infinite loop. The problem was that plat_get_my_entrypoint was using
"b" instead of "bl", so juno_do_reset_to_aarch_32_state was returning to
the caller of plat_get_my_entrypoint instead of stop the system with a
panic.
To avoid this problem juno_do_reset_to_aarch_32_state was modified to
call directly to plat_panic_handler if it tries to return.

asm_macros: set the default assembly code alignment to 4 byte
Assembly routines are usually defined by using "func" and "endfunc":
func foo
...
endfunc foo
Currently, the "func" macro does not specify ".align" directive
by default. It causes unaligned instruction under some circumstances.
As far as I tested, this problem happens for GCC 5 or older. It did
not happen for GCC 6 or newer. Taking into account that GCC 4.x / 5.x
is still used, make sure that assembly code is at least 4 byte aligned.
[ How to reproduce the problem ]
For example, use GCC 5.3 downloaded from Linaro:
http://releases.linaro.org/components/toolchain/binaries/5.3-2016.05/
aarch64-linux-gnu/gcc-linaro-5.3.1-2016.05-x86_64_aarch64-linux-gnu.tar.xz

The internal synchronisation timings of the FVP model version
11.0 build 11.0.34 and version 8.5 build 0.8.5202 has been
changed compared to older version of the models.
This change may have an impact on how the model behaves depending
on the workload being run on the model. For example test failures
have been seen where the primary core has powered on a secondary
core but was then starved of host CPU time and so was not able to
update power status, resulting a test failure due to an incorrect
status. This, or similar behaviour, is not to be expected from
real hardware platforms.
This patch adds a usage note on how to launch these models so
that internal synchronisation timing matches that of the older
version of the models, specifically adding the -Q 100 option.

Add new alignment parameter to func assembler macro
Assembler programmers are used to being able to define functions with a
specific aligment with a pattern like this:
.align X
myfunction:
However, this pattern is subtly broken when instead of a direct label
like 'myfunction:', you use the 'func myfunction' macro that's standard
in Trusted Firmware. Since the func macro declares a new section for the
function, the .align directive written above it actually applies to the
*previous* section in the assembly file, and the function it was
supposed to apply to is linked with default alignment.
An extreme case can be seen in Rockchip's plat_helpers.S which contains
this code:
[...]
endfunc plat_crash_console_putc
.align 16
func platform_cpu_warmboot
[...]
This assembles into the following plat_helpers.o:
Sections:
Idx Name Size [...] Algn
9 .text.plat_crash_console_putc
00010000 [...] 2**16
10 .text.platform_cpu_warmboot
00000080 [...] 2**3
As can be seen, the *previous* function actually got the alignment
constraint, and it is also 64KB big even though it contains only two
instructions, because the .align directive at the end of its section
forces the assembler to insert a giant sled of NOPs. The function we
actually wanted to align has the default constraint. This code only
works at all because the linker just happens to put the two functions
right behind each other when linking the final image, and since the end
of plat_crash_console_putc is aligned the start of platform_cpu_warmboot
will also be. But it still wastes almost 64KB of image space
unnecessarily, and it will break under certain circumstances (e.g. if
the plat_crash_console_putc function becomes unused and its section gets
garbage-collected out).
There's no real way to fix this with the existing func macro. Code like
func myfunc
.align X
happens to do the right thing, but is still not really correct code
(because the function label is inserted before the .align directive, so
the assembler is technically allowed to insert padding at the beginning
of the function which would then get executed as instructions if the
function was called). Therefore, this patch adds a new parameter with a
default value to the func macro that allows overriding its alignment.
Also fix up all existing instances of this dangerous antipattern.
