* Fix -Wsign-compare troubleNico Huber2019-07-311-1/+1
| | | | | | | | | | | Mostly by changing to `unsigned` types where applicable, sometimes `signed` types, and casting as a last resort.

* Unify non-shifted and shifted JEDEC accessCarl-Daniel Hailfinger2014-08-081-48/+0
| | | | | | | | | | | | | | | | | | Some Parallel bus chips have a 16-bit mode and an 8-bit mode. They use normal JEDEC addresses for 16-bit mode and shifted addresses (by 1 bit) for 8-bit mode. Some programmers can access them in 16-bit mode, but on all flashrom-supported programmers so far, we access them in 8-bit mode. This means we have to shift the addresses but apart from the addresses we can share the code. This patch makes this possible by checking the chip's FEATURE_ADDR_SHIFTED flag in common JEDEC functions and applying the right addresses respectively. Corresponding to flashrom svn r1840.

* Combine block_erase*_en29lv640b and block_erase*_m29f400bt respectivelyStefan Tauner2014-06-011-6/+4
| | | | | | | | | | | | | | | This patch combines two identical block and chip erase functions respectively: - Merge block_erase_m29f400bt and block_erase_en29lv640b into erase_block_shifted_jedec. - Merge block_erase_chip_m29f400bt and block_erase_chip_en29lv640b into erase_chip_block_shifted_jedec. Leave their implementations in en29lv640b.c for now. Corresponding to flashrom svn r1808.

* Add support for the Eon EN29LV640B chipRudolf Marek2012-04-141-0/+138
This chip needs special command sequences in 8 bit mode. Also, 8 bit programming needs actually 16bit double byte program. The chip is found on the Bifferos Bifferboard, for example.
