OK, did that.
Here are the results:

v2018.01
U-Boot SPL board init"Synchronous Abort" handler, esr 0x00070000
ELR:     e2030000a891a6e4
"Synchronous Abort" handler, esr 0x

v2018.03
U-Boot SPL board init"Synchronous Abort" handler, esr 0xffff0000
elr: 00000000ff8ca6fc lr : ffff0000ffffa7bc
"Synchronous Abort" handler, esr 0x

v2018.05
U-Boot SPL board init"Synchronous Abort" handler, esr 0x00070000
elr: 00000000ff8ca7a4 lr : 00000000ff8ca864
"Synchronous Abort" handler, esr 0x

v2018.07
U-Boot SPL board init"Synchronous Abort" handler, esr 0xff000000
elr: 00000000ff8ca8f0 lr : 00000000ff8ca9b0
"Synchronous Abort" handler, esr 0x

v2018.09
U-Boot SPL board init
(no more output)

mainline:
U-Boot SPL board init
(no more output)


It died when I call printf() at the start of board_init_r(). If I put
printf() anywhere inside spl_relocate_stack_gd() it is happy. Also
putc() works OK. So perhaps the code that calls that function is doing
something wrong? Some sort of stack problem?
