This turns out to be insufficient to fix the problem, since when

The caller iterates which calls iter_incr() which calls
bootdev_next_prio() again, which finds the same device and the loop
continues.

The global data structure has grown quite a lot over the years, being
the best place to put an important pointer or something that must be
accessed before and after relocation.
This series attempts to reduce the size a little, by moving some things
out and shrinking and aligning some fields.
Some fields are needed during init but not afterwards. To deal with this
a new 'boardf' structure is created, which sits on the stack and is only
present during board_init_f(). It is possible that more fields could
move to this struct, but for now only 4 are moved.
An assumption is made that an int is 32-bits wide on all architectures,
which seems to be true, but maintainers should be able to confirm.
Mostly the code-size impact is neutral, but the patch
'Use less space for environment fields' does increase U-Boot's size by
about 30 bytes on aarch64.
For firefly-rk3399 (64-bit) the size of global reduces from 456 to 368
