Re: [PATCH] mtd: spi-nor-core: Implement spi_nor_read_sfdp_dma_unsafe() for sfdp parse

During SFDP header parse and BFPT parse, structures in stack are used to perform spi_nor_read_sfdp() which expects a dma-safe buffer.

This commit introduces spi_nor_read_sfdp_dma_unsafe() to wrap spi_nor_read_sfdp() using a kmalloc'ed bounce buffer which is the same implementation in Linux (drivers/mtd/spi-nor/sfdp.c).
