 - Create distinct functions for mapping and unmapping for flash chips.
 - Map only when needed: map before probing and unmap immediately
   after it. Map again when a single chip was probed successfully before
   taking any actual actions and clean up afterwards.
 - Map special function chip registers centrally together with flash space
   instead of within (some) probing methods after successful probes.
 - Save the used base addresses of the mappings in struct flashctx as well.
 - Do not try to (un)map the zero-sized chip definitions that are merely hacks.
   This also fixes the printing of wrong warnings for these chip definitions
   introduced in r1765.

The core of this patch to support Bay Trail originally came from the
Chromiumos flashrom repo and was modified by Sage to support the
Rangeley/Avoton parts as well.
Because that was not complicated enough already Stefan Tauner refactored
and refined everything. Bay Trail seems to be the first Atom SoC able to
support hwseq. No SPI Programming Guide could be obtained so it is
handled similarly to Lynx Point which seems to be its nearest relative.

Possible values as well as encodings have changed in newer chipsets as follows.
 - Pre-PCH (i.e. ICH) chipsets had a maximum frequency of 33 MHz for all
   operations
 - Since Cougar Point the chipsets support dual output fast reads (encoded
   in bit 30).
 - Flash component density encoding has changed from 3 to 4 bits with Lynx
   Point, currently allowing for up to 64 MB chips.

Some Parallel bus chips have a 16-bit mode and an 8-bit mode. They use
normal JEDEC addresses for 16-bit mode and shifted addresses (by 1 bit)
for 8-bit mode. Some programmers can access them in 16-bit mode, but on
all flashrom-supported programmers so far, we access them in 8-bit mode.
This means we have to shift the addresses but apart from the addresses
we can share the code.

This patch makes this possible by checking the chip's FEATURE_ADDR_SHIFTED
flag in common JEDEC functions and applying the right addresses respectively.

Additionally to the existing S25FL128S......0 definition this patch
adds S25FL128P......0, S25FL128P......1 and S25FL128S......1, as well as
S25FL129P......0 and S25FL129P......1 definitions.
S25FL12xP seem to be the predecessor families of S25FL128S. All
associated chips can not be distinguished with RDID alone.

Besides the new chips, this patch also fixes the name of the  previously
supported S25FL128S model with uniform 256 kB sectors
(S25FL128P......1 not 0) and adds the hybrid sector version (0) as well.

Due to the shared IDs the user has to select the right chip manually
with the -c parameter. To make this even possible, this patch enlarges
the respective array for results to 6.

Apparently the erase function did never set any address before issuing the
erase commands. How could this ever work?
Also, according to PCH documentation crossing 256 byte boundaries is invalid
and may cause wraparound due to the flash chip's pages. Check for this on
reads as well as writes.

For arm64 with 32-bit userspace, pointers such as 0xff96ebf8 were
incorrectly getting converted to u64_t 0xffffffffff96ebf8 in the
spi_ioc_transfer struct which was causing ioctl()s to be rejected by
the kernel. With this patch we first cast to uintptr_t (to avoid
warnings on architectures where char * are not 64b wide) and then to
uint64_t which is always big enough and does not produce warnings.

points to the first invalid byte address. Refine respective checks
