Hello Simon,

At present arm defines CONFIG_SYS_GENERIC_GLOBAL_DATA, meaning that

actually set up before this, it just isn't zeroed.
If we zero the global data before calling board_init_f() then we
don't need to define CONFIG_SYS_GENERIC_GLOBAL_DATA.
Make this change (on arm32 only) to simplify the init process. I
don't have the ability to test aarch64 yet.

Looks good to me. I picked up this one instead
of my memset version.
Thanks, Jeroen
