Dear Heiko Schocher,
Hello,
just looked in the timer implementation for arm926ejs based boards, and found that there is just the at91, davinci, nomadik timer implementation fixed in actual u-boot. I want to cleanup this timers too, but there are kirkwood, mb86r0x, orion5x, spear, versatile archs which use a lastdec var, which is not in global_data.h defined. So the question is should we add a lastdec to global_data.h or is it Ok, if I use lastinc for cleaning up?
I would suggest to take tbu, tbl, lastinc out of the AT91FAMILY #ifdef to the generic part.
maybe "unify" last{inc,dec} into last_hw ? Because they are supposedly the last (hardware) decrementer/incrementer values from the previous call.
Or are there pending patches, which fix this issues for some (all) arm926ejs architectures?
at91 timer is still not perfect, it will break after 2**64 ticks. That is well after the end of the Solar System :)
