And even when it checks if the erase worked, the result of that check is
often ignored.
Convert all erase functions and actually check return codes
almost everywhere.
Check inside all erase_* routines if erase worked, not outside.
erase_sector_jedec and erase_block_jedec have changed prototypes to
enable erase checking.
Uwe successfully tested LPC on an CK804 box and SPI on some SB600 box.

has a huge chunk of chip and vendor IDs in the middle
Split them out into a separate flashchips.h and adjust #include wherever needed.

Add chip_{read,write}n to the external flasher infrastructure which read/write
n bytes at once. Fix a few places where the code used memcpy/memcmp although
that is strictly impossible with external flashers. Place a FIXME in the
layout.c code because usage is not totally clear and needs to be fixed to
support external flashers. As a nice side benefit, we get a noticeable speedup
for builtin flash reading which is now a memcpy() of the full flash area
instead of a series of single-byte reads.

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.

protect handling
All other chips call it wrprotect which is less confusing. As a side benefit,
flash_addr is now a name usable for other stuff.

Before we attempt trickery, we can simply rename the accessor functions.

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.

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.
