This FLASH resides in the external address space of the Local Bus State Controller. Note that as the CFI-FLASH has a run-time conflict with CPU bring-up, it will only be available when booting with SMP disabled. Signed-off-by: Geert Uytterhoeven --- Changes compared to RFC: - Use "cfi-flash" compatible value, - Add pin control, - Move to LBSC, - Depends on "[PATCH] ARM: shmobile: r8a7779: Reserve boot area when SMP is enabled".
