Constify variables where possible.
Initialize programmer-related variables explicitly in programmer_init to
allow running programmer_init from a clean state after
programmer_shutdown.
Prohibit registering programmer shutdown functions before init or after
shutdown.
Kill some dead code.
Rename global variables with namespace-polluting names.
Use a previously unused locking helper function in sst49lfxxxc.c.
This is needed for libflashrom.
Effects on the binary size of flashrom are minimal (300 bytes
shrinkage), but the data section shrinks by 4384 bytes, and that's a
good thing if flashrom is operating in constrained envionments.

remaining references to *_49fl00x. Now the only remaining and used function in pm49fl00x.c is unlock_49fl00x.
Added missing unlock to AMIC A49LF040A.
Added lock_49fl00x function; Trivial change.

All functions which just call probe_jedec and then map flash registers
are replaced by probe_jedec. All functions which call probe_jedec, map
flash registers and do something else can at least eliminate mapping
flash registers.
Fix logic inversion in probe_jedec to map flash registers on success
instead of on failure.
Change a few TIMING_IGNORED to TIMING_FIXME where probe_jedec is used.
Total savings: One probe function simplified, three probe functions
eliminated.

for many chip provided the only changes are the addresses are converted from
0x5555/0x2AAA to 0x555/0x2AA or similar. The patch mostly changes jedec.c, but
a few other files are changed because they use the jedec functions within
their own functions.
The patch also adds a copyright line to flashchips.c because of my recent work in converting AMD and Atmel chips to use struct erase_block.

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.

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.

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

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.

flashrom: Support Pm49FL004/2 Block Locking Registers
The PMC chips understand both LPC and FWH flash commands. When in FWH mode
(MSR_DIVIL_BALL_OPT(0x51400015) = 0x00000f7d on 5536 boards) the Block
Locking Registers by default lock the flash chip for write and erase - in
addition to any chipset write protection.
This patch adds unlock operations before Pm49FL004/2 write and erase, and
it includes an svn mv pm49fl004.c pm49fl00x.c
Thanks go to Nikolay for this patch.
