Carl-Daniel Hailfinger 3b1a955cce 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.

Carl-Daniel Hailfinger ac12ecd27a 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.

Claus Gindhart b19973eb8b The generic jedec.c does not work for the ST M50FLW flash
devices, because they need an unlock command first.
For this reason, ST M50FLW support is moved to a
new HW support module, because any change in jedec.c
would bear the risk to cause problems with the already
supported devices.

It's already tested with ST M50FLW080A; the other
chips of this family i dont have available, so i couldnt
test it.
