SK_CSR becomes 0x044a after reset. And LED is irrelevant.

That's a timer interrupt status bit.

sk_init() will set SK_IMR to zero. So there's no problem either.

Don't know about this one. Maybe we should clear it?

Hm. No idea.

Lots of timer stuff. Maybe we should reset the TIMERCTL registers?

sk_init() writes 2 (UNRESET) into SK_RAMCTL. But yours is already
unreset. Maybe we should reset it first?

It probably doesn't matter, because GMAC_CTRL and GPHY_CTRL are reset
by our driver. GMAC_ISR is just a status flag?

Remember that the registers are little-endian. So it is SK_ISR_TIMER,
which was certainly set due to some timer, which SK98 likes to use.
As we mask out all interrupts with SK_IMR=0 it shouldn't matter.
Before we start manipulating registers we should also check their
status after the chip reset. A modified altboot can be downloaded from
ftp://ftp.netbsd.org/pub/NetBSD/misc/phx/sandpoint/altboot_skreset.bin.gz
Here is my register dump after reset:
