The semantic patch I used in r418 to make the original conversion to
accessor functions was missing one isomorphism:
a[b] <=> *(a+b)
The semantic patcher Coccinelle was used to create this patch. Semantic
patch follows:
@@
typedef uint8_t;
expression a;
volatile uint8_t *b;
@@
- b[a]
+ *(b + a)
@@
expression a;
volatile uint8_t *b;
@@
- *(b) = (a);
+ chip_writeb(a, b);
@@
volatile uint8_t *b;
@@
- *(b)

@@
type T;
T b;
@@
(
chip_readb
|
chip_writeb

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

flashrom: 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.

Coding-style fixes for flashrom, partly indent-aided (trivial).

set w39v080fa to fully supported. I'm am flashing this chip several times a
day.
Also enable unlocking which is only needed when running coreboot, that slipped
in the original commit and through the original review ;-) So it must be
trivial enough.

oops. forgot to add the file.
Support for the Winbond W39V080FA series of chips.
Support for flashing on the Kontron 986LCD-M board.
