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.

The caching policy for romstage was previously using a 32KiB
of cache-as-ram for both the MRC wrapper and the romstage stack/data.
It also used a 32KiB code cache region. The BWG's limitations for
the code and data region before memory is up was wrong. It consists
of a 16-way set associative 1MiB cache. As long as enough addresses
are not read there isn't a risk of evicting the data/stack.
Now create a 64KiB cache-as-ram region split evenly between romstage
and the MRC wrapper. Additionally cache the memory just below
4GiB in CBFS size. This will cover any code and read-only data needed.
