Subject: [PATCH] Add AMIC A29002
This patch adds support to the AMIC A29002 chip in its top and bottom
configuration to flashrom. Additionally, the alphabetic order of the
AMIC chips was fixed.
The datasheet is at <http://www.amictechnology.com/pdf/A29002.pdf>.
A29002T PREW functionality was tested and works.
This flash chip has asymmetric sector layout so it is important to use the
mx29f002 driver, which does chip erase before writing, rather than am29f040b,
which uses sector erase.
Corresponding to flashrom svn r299 and coreboot v2 svn r3415.
