Re: [U-Boot] [PATCH 7/9 V3] prepare joining at91rm9200 into at91
+/* reset time */
+at91_tc_t *tc = (at91_tc_t *) AT91_TC_BASE;
+lastinc = readl(tc-tc[0].cv) 0x;
+timestamp = 0;
rm9200 did not zero out the top bits
Is this needed ?
The datasheet say not, is bit 16 to 31 of cv high or low.
+typedef struct at91_mc {
