Most of the chips on the market only feature a single bank. However, new chips may support more than a single bank, with the possibility to parallelize some operations. Let's introduce an INFOB() macro which also takes a n_bank parameter. Signed-off-by: Miquel Raynal <miquel.raynal@bootlin.com> --- drivers/mtd/spi-nor/core.h | 4 ++++ 1 file changed, 4 insertions(+)
