Re: [U-Boot] [PATCH 04/20] tegra: Provide more accurate microsecond time

Add an implementation of the timer functions for tegra, so that timing is more accurate. Tegra has a 1 microsecond timer for this purpose.

I'm a bit confused about this:

include/configs/tegra-common.h:32:#define CONFIG_SYS_TIMER_COUNTER NV_PA_TMRUS_BASE

lib/time.c:

#ifdef CONFIG_SYS_TIMER_COUNTER unsigned long notrace timer_read_counter(void) { #ifdef CONFIG_SYS_TIMER_COUNTS_DOWN return ~readl(CONFIG_SYS_TIMER_COUNTER); #else return readl(CONFIG_SYS_TIMER_COUNTER); #endif }

Doesn't that provide the same set of features, without requiring Tegra-specific code?
