#125 new defect

BCM5785 / HT1000 reset functions

Reported by: "Marco Schmidt" <mashpb@…> Owned by: somebody
Priority: minor Milestone:
Component: coreboot Keywords: BCM5785 reset
Cc: Dependencies:
Patch Status: there is no patch

Description

/coreboot-v2/src/southbridge/broadcom/bcm5785/bcm5785_early_setup.c @ 4028

void hard_reset(void) void soft_reset(void)

According to HT1000 programmers guide 1.3, section "cf9 reset" writing a 0x6 to 0x0cf9 is hard reset, writing 0x4 is soft reset. Current implementation for hard_reset accesses "reserved" bits. Current implementation for soft_reset implements hard reset. However writing 0x4 as a soft reset does not work in my case.

Please review/verify.
