Hi Tom, I stumbled over your commit b352dde1ea715e8481946ec7d8086b3c3eb126ae where you removed timer_init() from .../am33xx/board.c.
In the commit message it's written that timer_init will be called earlier. However, since this commit udelay will not generate correct delays in spl code in our am335xx based boards. I'm wondering where the timer_init shold be placed. grep-ing the code I see that we have a call in spl.c but I this is too late.
Doing some measurements, with this commit udelay is not correct at the time of:
* board_init_ddr() * spl_siemens_board_init()
I'm guessing that it might be a problem for other am33xx boards too, but I didn't verify this.
Right now I just put it back into am33xx/board.c but maybe you have a better idea.
Kind regards Sam
