4 Subject: [PATCH] mtd: spi-nor: rename SPINOR_OP_* macros of the 4-byte address
5 op codes
6
7 This patch renames the SPINOR_OP_* macros of the 4-byte address
8 instruction set so the new names all share a common pattern: the 4-byte
9 address name is built from the 3-byte address name appending the "_4B"
10 suffix.
11
12 The patch also introduces new op codes to support other SPI protocols such
13 as SPI 1-4-4 and SPI 1-2-2.
14
15 This is a transitional patch and will help a later patch of spi-nor.c
16 to automate the translation from the 3-byte address op codes into their
17 4-byte address version.
