From 322c512f476f07e960cecd447ef22c15bed0e5f1 Mon Sep 17 00:00:00 2001 From: Greg Ungerer Date: Mon, 21 Sep 2020 12:55:20 +1000 Subject: m68knommu: include SDHC support only when hardware has it The mere fact that the kernel has the MMC subsystem enabled (CONFIG_MMC enabled) does not mean that the underlying hardware platform has the SDHC hardware present. Within the ColdFire hardware defines that is signified by MCFSDHC_BASE being defined with an address. The platform data for the ColdFire parts is including the SDHC hardware if CONFIG_MMC is enabled, instead of MCFSDHC_BASE. This means that if you are compiling for a ColdFire target that does not support SDHC but enable CONFIG_MMC you will fail to compile with errors like this: arch/m68k/coldfire/device.c:565:12: error: ‘MCFSDHC_BASE’ undeclared here (not in a function) .start = MCFSDHC_BASE, ^ arch/m68k/coldfire/device.c:566:25: error: ‘MCFSDHC_SIZE’ undeclared here (not in a function) .end = MCFSDHC_BASE + MCFSDHC_SIZE - 1, ^ arch/m68k/coldfire/device.c:569:12: error: ‘MCF_IRQ_SDHC’ undeclared here (not in a function) .start = MCF_IRQ_SDHC, ^ Make the SDHC platform support depend on MCFSDHC_BASE, that is only include it if the specific ColdFire SoC has that hardware module.
