From 3e85be98875a568b762afd2e9bfd136e22106558 Mon Sep 17 00:00:00 2001 From: Michael Walle Date: Fri, 8 Sep 2023 12:16:33 +0200 Subject: [PATCH] mtd: spi-nor: add SNOR_ID() and SNOR_OTP() After all the preparation, it is now time to introduce the new macros to specify flashes in our database: SNOR_ID() and SNOR_OTP(). An flash_info entry might now look like: { .id = SNOR_ID(0xef, 0x60, 0x16), .otp = SNOR_OTP(256, 3, 0x1000, 0x1000), .flags = SPI_NOR_HAS_LOCK | SPI_NOR_HAS_TB, } Signed-off-by: Michael Walle Link: https://lore.kernel.org/r/20230807-mtd-flash-info-db-rework-v3-15-e60548861b10@kernel.org Signed-off-by: Tudor Ambarus --- drivers/mtd/spi-nor/core.h | 14 ++++++++++++++ 1 file changed, 14 insertions(+) diff --git a/drivers/mtd/spi-nor/core.h b/drivers/mtd/spi-nor/core.h index 6d1870d5484d..14c1aa63bc51 100644 --- a/drivers/mtd/spi-nor/core.h +++ b/drivers/mtd/spi-nor/core.h @@ -561,6 +561,20 @@ struct flash_info { const struct spi_nor_fixups *fixups; }; +#define SNOR_ID(...) \ + (&(const struct spi_nor_id){ \ + .bytes = (const u8[]){ __VA_ARGS__ }, \ + .len = sizeof((u8[]){ __VA_ARGS__ }), \ + }) + +#define SNOR_OTP(_len, _n_regions, _base, _offset) \ + (&(const struct spi_nor_otp_organization){ \ + .len = (_len), \ + .base = (_base), \ + .offset = (_offset), \ + .n_regions = (_n_regions), \ + }) + #define SPI_NOR_ID_2ITEMS(_id) ((_id) >> 8) & 0xff, (_id) & 0xff #define SPI_NOR_ID_3ITEMS(_id) ((_id) >> 16) & 0xff, SPI_NOR_ID_2ITEMS(_id) -- 2.25.1
