This patch removes the extremely dangerous unprotect_jedec function
which is not used at all within flashrom code, and renames the
misleadingly named protect_jedec function to start_program_jedec.

Calls to protect_jedec after flashing are removed, because a) on LPC
chips, the command sent by protoct_jedec is not even in the datasheet
and b) on parallel chips, the block write command issued before already
contained the software protection sequence, so software protection is
definitely enabled.

This patch also removes two clones of protect_jedec

Background: JEDEC Software Data Protection started as an optional
feature, which was disabled on the first single-voltage-flash chips.
The software data protection is the need to prefix a write with a magic
"write enable" command, while without write protection every write
access into the chip's address space modifies flash content. This magic
write enable command also tells the flash chip that the programmer
obviously support sending write-enable commands and turns off the "any
write modifies flash content" mode. There also exist a two-command (6
writes) sequence that disables Software Data Protection completey, which
should only ever be used to prepare updating with a device that can't
handle software data protection.

Use the correct reset sequence for 82802AB. Detailed explanation:
The reset sequence before ID reading was correct, so ID always
worked. But the reset sequence after ID reading was a copy-paste
leftover from probe_jedec and didn't have any effect. I dug up
flash_and_burn from the freebios-v1 tree and found out that 82802ab.c
was indeed a copy of jedec.c with lots of experimental unannotated #if 0
and #if 1.
About the wait_82802ab change:
Before the patch, wait_82802ab entered read status mode, switched to ID
mode, then tried an incorrect and unsupported JEDEC command to exit ID
mode. Nobody ever saw that this failed because all subsequent function
calls had the correct reset sequence at the beginning.
With the patch, wait_82802ab enters read status mode, then switches back
to read mode with the official reset command.

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.

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.

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.

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.

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.

Flash pages, which where excluded from updating using the exclude or the
layout option, as well as areas, whose flash contents already contain
the desired data, will be skipped. These ensures absolute data security
of critical areas (BIOS boot block), e.g. against a sudden power off or
a CPU hangup during flashing. As a nice side effect, it speeds up the
flash process, if the BIOS to be flashed is very similar to the version
in flash.
