Bay Trail has the following types of resets it supports: - Soft reset (INIT# to cpu) - write 0x1 to I/O 0x92 - Soft reset (INIT# to cpu)- write 0x4 to I/0 0xcf9 - Cold reset (S0->S5->S0) - write 0xe to I/0 0xcf9 - Warm reset (PMC_PLTRST# assertion) - write 0x6 to I/O 0xcf9 - Global reset (S0->S5->S0 with TXE reset) - write 0x6 or 0xe to 0xcf9 but with ETR[20] set. While these are documented this support currently provides support for 2nd soft reset as well as cold and warm reset. BUG=chrome-os-partner:23249 BRANCH=None TEST=Built and booted.
