It's been on for all boards per default since several years now
and the old code path probably doesn't even work anymore. Let's
just have one consistent way of doing things.

This reverts commit ca6e1f6c04c96c435bdbf30a1b88cab0e5be330b.
The packet size changes ends up corrupting the flash when booting
Persimmon. I did figure out that the maximum number of bytes that
can be sent is actually 8 bytes according to the sb800 spec. There
must be additional problems beyond that since setting the packet
size to 8 still causes problems.

According to spi.c in src/southbridge/amd/agesa/hudson
readwrite = (bytesin + readoffby1) << 4 | bytesout;
We can see that Hudson limits the SPI programming data
packet size as 15.
We used to write data to SPI in dword mode. It didn't
take full advantage of the data packet size. We need to
leverage that to speed up programming time.

Since there are and will be other files in nb/sb folders, we change
the general spi.h to a file name which is not easy to be duplicated.

It has worked up to now because the region is already erased
the first time the board boots, and every additional boot the
same data is being written over the old data.(by Dave Frodin)

The SB800 and Hudson now support adding the IMC ROM which runs from the same
chip as coreboot. When the IMC is running, write or erase commands sent to
the spi bus will fail, and the IMC will die. To fix this, we send a request
to the IMC to stop fetching from the SPI rom while we write to it. This
process (in one form or another) is required for writes to the SPI bus while
the IMC is running.
Because the IMC can take up to 500ms to respond every time we claim the
bus, this patch tries to keep the number of times we need to do that to a
minimum. We only need to claim the bus on writes, and using a counter for
the semaphore allows us to call in once to claim the bus at the beginning
of a number of transactions and it will stay claimed until we release it
at the end of the transactions.
Claim() - takes up to 500ms hit
claim() - no delay
erase()
release()
claim() - no delay
write()
release()
Release()

Remove the old, unflexible code for storing S3 data in SPI flash.
Refer to flashrom. Tested on Parmer.

We thought about two ways to do this change. The way we decided to try
was to
1. drop all ops from devices in romstage
2. constify all devices in romstage (make them read-only) so we can
compile static.c into romstage
3. the device tree "devices" can be used to read configuration from
the device tree (and nothing else, really)
4. the device tree devices are accessed through struct device * in
romstage only. device_t stays the typedef to int in romstage
5. Use the same static.c file in ramstage and romstage
We declare structs as follows:
ROMSTAGE_CONST struct bus dev_root_links[];
ROMSTAGE_CONST is const in romstage and empty in ramstage; This
forces all of the device tree into the text area.
So a struct looks like this:
static ROMSTAGE_CONST struct device _dev21 = {
#ifndef __PRE_RAM__
.ops = 0,
#endif
.bus = &_dev7_links[0],
.path = {.type=DEVICE_PATH_PCI,{.pci={ .devfn = PCI_DEVFN(0x1c,3)}}},
.enabled = 0,
.on_mainboard = 1,
.subsystem_vendor = 0x1ae0,
.subsystem_device = 0xc000,
.link_list = NULL,
.sibling = &_dev22,
#ifndef __PRE_RAM__
.chip_ops = &southbridge_intel_bd82x6x_ops,
#endif
.chip_info = &southbridge_intel_bd82x6x_info_10,
.next=&_dev22
};
