[U-Boot] [PATCH 0/2] improve hello_world standalone application for arm

[Max Krummenacher]

This series addresses
- hardcoded entry address, use LOADADDR if available as the entry point instead
- fix thumb build, jumping with 'go' to the entry point expects arm code

Note that in addition to the two fixes I've seen random freezes
or 'random' printed stuff when using an early linaro gcc 6 compiler.
Adding an initialized variable helped in that case
static int dummy_var_in_text = 1;
I assume that this forces alignment of some linker sections.
(e.g. I see that __bss_start points to 0x1201027e, with the variable
this moves to 0x12010280)

However with the current linaro compilers this does not happen so I
don't propose a patch for this issue.
Linaro GCC 5.4-2017.05 5.4.1 20170404
Linaro GCC 6.3-2017.05 6.3.1 20170404
Linaro GCC 7.1-2017.05 7.1.1 20170510
