v10:
* Further explanation on adding Macronix manufacturer ID in ID table.
* Correct some typos.

v9:
* Change the name of the configuration register 2 for Macronix Octal 
  flash.
* Fix the bit value in __pad of struct spi_mem_op.
* Use the local variable proto instead of nor->read_proto.

v8:
* Supplement missing S-o-b
* Remove function spi_nor_is_octal_dtr_swab16
* Split IDs by MX25 & MX66
* Add dump of capability in debugfs
* Add dump of parameters in debugfs
* Add dump of result for mtd-utils tests
* Add SNOR_ID(0xC2) in last of Macronix ID table

v7:

v2:
* Following exsiting rules to re-create Macronix specify Octal DTR 
  method.
* change signature to jaimeliao@mxic.com.tw
* Clear sector size information in flash INFO.

Made the changes that I specified in replies. SFDP
"Command Sequences to Change to Octal DDR (8D-8D-8D) Mode" can be parsed
later on.
