arm: Move bootstage record for board_init_f() to after arch_cpu_init()
The timer may be inited in arch_cpu_init() so it is not safe to make a bootstage mark before this is called. Arrange the code to fix this. Note: The question was raised as to why we don't keep all archs in sync. PowerPC doesn't have specific bootstage markers at present (although it does use boot progress). I hope that the generic board series will solve this problem in general, but in the meantime this is a real problem, and only in ARM. We now get a correct time for board_init_f: Timer summary in microseconds: Mark Elapsed Stage 0 0 reset 100,000 100,000 spl_start 848,530 748,530 board_init_f 907,301 58,771 board_init_r 910,478 3,177 board_init Signed-off-by: Simon Glass <sjg@chromium.org>
