New Revision: 1870
URL: http://flashrom.org/trac/flashrom/changeset/1870
Log:
Add support for Eon EN25P Series.
These are very similar to Eon's EN25B series but unlike those the
EN25P has uniform sectors (of 32 and 64 kB). They can not be
distinguished by RDID alone but the RES and REMS IDs are different
and hence could be detected eventually in the future. This patch
also refines tiny bits of the EN25B series.
The series includes:
- EN25P05
- EN25P10
- EN25P20
- EN25P40
- EN25P80
- EN25P16
- EN25P32
- EN25P64
