Marc Schink 38f94a2677 flash/nor: Do not update 'is_erased'
Remove useless setting of the 'is_erased' flag after a flash
modification. Also, remove code that erroneously depends on
this flag.

Keep the flag for now since it is still used by the
erase_check() functionality.

See commit 07da3b3913

Antonio Borneo 28c24a5c41 openocd: fix simple cases of Yoda condition
There are ~900 Yoda conditions to be aligned to the coding style.
For recurrent Yoda conditions it's preferable using a trivial
script in order to minimize the review effort.
E.g. comparison of uppercase macro/enum with lowercase variable:
	- ...(ERROR_OK == retval)...
	+ ...(retval == ERROR_OK)...

Patch generated automatically with the command:
	sed -i \
	's/(\([A-Z][A-Z0-9_]*\) \([=!]=\) \([a-z][a-z0-9_]*\))/(\3 \2 \1)/g' \
	$(find src/ -type f)

While there, remove the braces {} around a single statement block
to prevent warning from checkpatch.

Fredrik Hederstierna a8c8c238f2 str9x: faster flash erase of entire chip
The patch improves flash erase for STR9x in case of a full bank erase.
Then the chip erase command is used instead which improves speed significantly.

Also I think it might help if e.g. STR912 enters some state where flash banks are locked, and a chip erase command is the key for unlocking the flash.
