> i.MX platforms provide large AHB mapped space for QSPI, each > controller has 256MB. However, current driver only maps small > size (AHB buffer size) of AHB space, this implementation > causes i.MX failed to boot M4 with QSPI XIP image. > Add config CONFIG_FSL_QSPI_AHB_FULL_MAP (default enabled for i.MX) > to address above problem. > When the config is set: > 1. Full AHB space is divided to each CS. > 2. A dedicated LUT entry is used for AHB read only. > 3. The MODE instruction in LUT is replaced to standard ADDR instruction > 4. The address in spi_mem_op is used to SFAR and AHB read > Signed-off-by: Ye Li <[email protected]> > Reviewed-by: Ashish Kumar <[email protected]> > Reviewed-by: Kuldeep Singh <[email protected]> Applied to u-boot-imx, master, thanks !
