From: Kazuhiko Sakamoto <sakamoto.kazuh...@socionext.com>
Support 4-bytes address for erase and write, so that we can
access whole region of SPI-NOR Flash(64MiB) implemented on the
Developerbox.
This commit also fixes the wrong macro name. SPINOR_OP_SE and
SPINOR_OP_SE_4B is the commoand for 64KB block erase,
it must be SPINOR_OP_BE and SPINOR_OP_BE_4B.
