b51e58e50f Use __clang_version__ macro
Newer llvm/clang versions (since r102686) have a __clang_version__ macro
which can be used to print the exact clang version.

Fix a case where chip_to_probe was referenced twice via extern, once at
the function level and once in a global include file. Found by latest
clang.

04aa59a864 Standardize on using __func__ instead of __FUNCTION__
The __func__ variant is standardized in C99 and recommended to be
used instead of __FUNCTION__ in the gcc info page.

Only _very_ old versions of gcc did not know about __func__, but we've
been using both __func__ and __FUNCTION__ for a long while now, and
nobody complained about this, so all our users seem to use recent
enough compilers.

414bd320ac Verbose probe output is split across multiple lines for some probe functions
This makes visual inspection and grepping a lot harder than necessary.
Remove line breaks where appropriate. Some error messages should end up
on stderr instead of just being displayed in verbose mode.

Thanks to Maciej Pijanka for testing.

ca8bfc6c22 Add programmer-specific delay functions
Add external programmer delay functions so external programmers can
handle the delay on their own if needed.

5820f42ef2 Introduce a type "chipaddr" to abstract the offsets within flash regions
Use chipaddr instead of volatile uint8_t * because when we access chips
in external flashers, they are not accessed via pointers at all.

Benefits: This allows us to differentiate between volatile machine
memory accesses and flash chip accesses. It also enforces usage
of chip_{read,write}[bwl] to access flash chips, so nobody will
unintentionally use pointers to access chips anymore. Some unneeded
casts are removed as well. Grepping for chip operations and machine
memory operations doesn't yield any false positives anymore.

Compile tested on 32 bit and 64 bit Linux.

0472f3d826 FreeBSD definitions of (read|write)[bwl] collide with our own
Before we attempt trickery, we can simply rename the accessor functions.

61a8bd27fb Use helper functions to access flash chips
Right now we perform direct pointer manipulation without any abstraction
to read from and write to memory mapped flash chips. That makes it
impossible to drive any flasher which does not mmap the whole chip.

Using helper functions readb() and writeb() allows a driver for external
flash programmers like Paraflasher to replace readb and writeb with
calls to its own chip access routines.

This patch has the additional advantage of removing lots of unnecessary
casts to volatile uint8_t * and now-superfluous parentheses which caused
poor readability.

I used the semantic patcher Coccinelle to create this patch. The
semantic patch follows:
@@
expression a;
typedef uint8_t;
volatile uint8_t *b;
@@
- *(b) = (a);
+ writeb(a, b);
@@
volatile uint8_t *b;
@@
- *(b)
+ readb(b)
@@
type T;
T b;
@@
(
 readb
|
 writeb
)
 (...,
- (T)
- (b)
+ b
 )

In contrast to a sed script, the semantic patch performs type checking
before converting anything.

b9f617448d Add support for AMIC Technology A49LF040A and do not probe W29EE011 anymore
Jens sent the first patch that added A49LF040A to flash.h and flashchips.c
using _jedec and _49lf040 functions.

An issue was found with probe_w29ee011() for the Winbond W29EE011, which
caused the A49LF040A to no longer respond to any commands.

Ward made a patch to disable probing by default for the W29EE011 following
some discussion. Using -c W29EE011 will make flashrom probe for the chip.

Peter did some more datasheet diving and found that the Pm49FL00x functions
suited this chip quite well because of the block locking registers in
A49LF040A, and finally tested PROBE READ ERASE WRITE to work on ALIX.3c3.

Ward confirmed that this works on alix.2c3 too.
