From 542a4304f043703cf894e0c7f5d21f438c62fc5c Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Mon, 10 Dec 2018 21:38:16 +0100 Subject: mtd: atmel-quadspi: disallow building on ebsa110 commit 2a9d92fb3a1282a4659f1bb6d5684018846537b7 upstream. I ran into a link-time error with the atmel-quadspi driver on the EBSA110 platform: drivers/mtd/built-in.o: In function `atmel_qspi_run_command': :(.text+0x1ee3c): undefined reference to `_memcpy_toio' :(.text+0x1ee48): undefined reference to `_memcpy_fromio' The problem is that _memcpy_toio/_memcpy_fromio are not available on that platform, and we have to prevent building the driver there. In case we want to backport this to older kernels: between linux-4.8 and linux-4.20, the Kconfig entry was in drivers/mtd/spi-nor/Kconfig but had the same problem.
