[coreboot] Winbond W83627EHG dump

[Nico Huber]

Hi Elyes,

in the code you pasted yesterday, the IO BAR for the HWM was set
incorrectly. You had:

    pnp_write_register(cfg_port, 0x60, 0xa0);

where it should write 0x0a. Some lines above you tried to set 0xa00,
also not correct because the code expects it at 0xa10 (HWM_BASE).

Hope that helps,
Nico
