Subject: [PATCH] mtd: spi-nor: rename SPINOR_OP_* macros of the 4-byte address
|
|
op codes
|
|
|
|
This patch renames the SPINOR_OP_* macros of the 4-byte address
|
|
instruction set so the new names all share a common pattern: the 4-byte
|
|
address name is built from the 3-byte address name appending the "_4B"
|
|
suffix.
|
|
|
|
The patch also introduces new op codes to support other SPI protocols such
|
|
as SPI 1-4-4 and SPI 1-2-2.
|
|
|
|
This is a transitional patch and will help a later patch of spi-nor.c
|
|
to automate the translation from the 3-byte address op codes into their
|
|
4-byte address version.
