Enable device tree control of SPI flash, and use this to implement
memory-mapped SPI flash, which is supported on Intel chips.

Some SPI flash controllers (e.g. Intel ICH) have a limit on the number of
bytes that can be in a write transaction. Support this by breaking the
writes into multiple transactions.

Rather than each device having its own way to allocate a SPI flash
structure, use the new allocation function everywhere. This will make it
easier to extend the interface without breaking devices.
Signed-off-by: Simon Glass <sjg@chromium.org>
At present it is difficult to extend the SPI flash structure since
all devices allocate it themselves, and few of them zero all fields.
Add a new function spi_flash_alloc() which can be used by SPI devices
to perform this allocation, and thus ensure that all devices can
better cope with SPI structure changes.

Commit a4ed3b6 "sf: inline data constants" modified winbond.c's page_size
from 256 to 4096. This prevents either/both of "sf write" writing the
correct data, or "sf read" from reading the correct data back.
This allows U-Boot running on Compulab Tegra to upgrade itself.

There are more than the M25Pxx serial flashs that can be
used with the stmicro driver, for example: the M25PXxx or
N25Qxx serie. All these chips have burned in the original
stmicro manufacture id 0x20 together with a standard
two-byte signature.
In preperation to support all these chips the stmicro driver
have to decode the full two-byte signature.

The only two drivers to write the status register do it in the same
way, so unify the implementations. This also makes the block unlock
logic the same.

The local sst enable/disable write funcs don't really add anything
over the common API, so just inline the common calls directly.

Analysis of the flash drivers shows that they all use 0x20 if the erase
size is 4KiB, or 0xd8 if it's larger. So with this info in hand, we can
unify all the erase functionality in one place.

I imagine much of these constants are due to copy & pasting previous
drivers rather than an actual reflection of the hardware layout. At
any rate, inline the info that we don't care about externally as it
shrinks things nicely.

In an effort to unify the spi flash drivers further, drop all the

Every board currently defines this to the same value, so just default
to that to avoid having to make everyone do the same thing.

We want to show the length, so multiplying by sector size makes no sense.
This is a hold over from the erase code before the big refactor.

Newer SST flashes have dropped the Auto Address Increment (AAI) word
programming (WP) modes in favor of the standard page programming mode
that most flashes now support. So add a flags field to the different
flashes to support both modes with new and old styles.
