The currently used write functions (wrappers) all use helpers which
perform the actual write (inner functions).

The signature of the write wrappers is: int write_chip(struct flashchip
*flash, uint8_t * buf);

The signature of the inner write functions varied a lot. This patch
changes them to: int write_part(struct flashchip *flash, uint8_t *src,
int start, int len);

Did you know that flashrom has only 8 inner write functions for all
flash chips? write_page_write_jedec_common write_sector_jedec_common
write_sector_28sf040 spi_chip_write_256_new spi_chip_write_1_new
spi_aai_write_new write_page_82802ab write_page_m29f400bt

Export all inner write functions.

Change the function signature of wait_82802ab to eliminate single-use
variables.

Remove an error message in write_page_m29f400bt which was printed for
every byte written regardless of success.

Progress printing should be handled in the generic code, and will end up
there once partial write is possible.

Flashrom had an implicit erase-on-write for most flash chip and
programmer drivers, but it was not entirely consistent.

Some drivers had their own hand-rolled partial update functionality
which made handling partial updates from generic code impossible.

Move implicit erase out of chip drivers, and kill some dead erase
functions at the same time. A full chip erase is now performed in the
generic code for all flash chips on write, and after that the whole chip
is written.

Thanks to Johannes Sjölund for reporting that the Bus Pirate init could
not deal with a Bus Pirate which is already in binary Bitbang mode.

This is caused by a combination of the slowness of the Bus Pirate, the
slowness of USB and a fast serial port flush routine which just flushes
the buffer contents and does not wait until data arrival stops.

Make the Bus Pirate init more robust by running the flush command 10
times with 1.5 ms delay in between.

AMD SB700 and later have an integrated microcontroller (IMC) which runs
from shared flash.

The IMC will happily issue reads while we write, issue writes while we
read, and generally cause lots of havoc due to the concurrent accesses
it performs while flashrom is running. A failing or corrupted read can
be detected since r1145, and the worst case is that the read aborts and
the user has to retry. A failing write is much more serious. It can
be detected since r1145, but if the SPI interface locks up, we can't
continue writing nor can we read the current chip contents.

If the IMC is inactive, there is no reason to worry. If the IMC is
active, flashrom will refuse to erase/write the chip with this patch.

The correct fix would be to stop the IMC during flashing, but apparently
the relevant registers are undocumented, so we take the safe route for
now until someone from AMD can give us more info.

Some flash chips need time to exit ID mode, and while we take care of
correct timing for the matching probe, subsequent probes may have
totally different timing, and that can lead to garbage responses from
the flash chip during the first accesses after the probe sequence is
done.
Delay 100 ms between the last probe and any subsequent operation.
To ensure maximum correctness, we would have to reset the chip first in
case the last probe function left the chip in an undefined (non-read)
state. That will be possible once struct flashchip has a .reset
function.

This fixes unstable erase/read/write for some flahs chips on nic3com and
possible other use cases as well.

Thanks to Maciej Pijanka for reporting the issue and testing patches.

SPI bitbanging on devices which speak SPI natively has a dual-use
problem: We need to shut down normal SPI operations to do the bitbanging
ourselves. Once we're done, it makes a lot of sense to reenable "normal"
SPI operations again. Add request_bus/release_bus functions to struct
bitbang_spi_master.
Add a bitbang shutdown function (not used yet).
Change MCP SPI and Intel NIC SPI to use the new request/release bus
infrastructure.
Cosmetic changes to a few error messages (80 column limit).

There are multiple possible strategies for bus request/release:
- Request at the start of a SPI command, release immediately afterwards.
- Request at the start of a SPI multicommand, release once all commands
of the multicommand are done.
- Request on programmer init, release on shutdown.
Each strategy has its own advantages. For now, we will stay with the
first strategy which worked fine so far.

ICH SPI has the ability to restrict SPI read/write accesses to a given
address range. The low end of the range is configurable by the BIOS (and
by flashrom if the BIOS didn't lock down the flash interface), the high
end of the range is 0xffffff (2^24-1).
This patch checks for an address range restriction and uses the low end
of the allowed range as base for SPI reads. A similar workaround for
REMS/RES opcodes has been committed in r500.

This fixes read on the Intel D945GCLF mainboard where the stock BIOS
enforces a restricted address range.
Please note that writes need the same fix, but for architectural reasons
that fix will be merged once partial write is available.
