m68k: coldfire/device.c: only build for MCF_EDMA when h/w macros are defined
[ Upstream commit e6e1e7b19fa132d23d09c465942aab4c110d3da9 ]
When CONFIG_MCF_EDMA is set (due to COMPILE_TEST, not due to
CONFIG_M5441x), coldfire/device.c has compile errors due to
missing MCFEDMA_* symbols. In the .config file that was provided,
CONFIG_M5206=y, not CONFIG_M5441x, so <asm/m5441xsim.h> is not
included in coldfire/device.c.
Only build the MCF_EDMA code in coldfire/device.c if the MCFEDMA_*
hardware macros are defined.
Fixes these build errors:
../arch/m68k/coldfire/device.c:512:35: error: 'MCFEDMA_BASE' undeclared here (not in a function); did you mean 'MCFDMA_BASE1'?
512 | .start = MCFEDMA_BASE,
../arch/m68k/coldfire/device.c:513:50: error: 'MCFEDMA_SIZE' undeclared here (not in a function)
513 | .end = MCFEDMA_BASE + MCFEDMA_SIZE - 1,
../arch/m68k/coldfire/device.c:517:35: error: 'MCFEDMA_IRQ_INTR0' undeclared here (not in a function)
517 | .start = MCFEDMA_IRQ_INTR0,
../arch/m68k/coldfire/device.c:523:35: error: 'MCFEDMA_IRQ_INTR16' undeclared here (not in a function)
523 | .start = MCFEDMA_IRQ_INTR16,
../arch/m68k/coldfire/device.c:529:35: error: 'MCFEDMA_IRQ_INTR56' undeclared here (not in a function)
529 | .start = MCFEDMA_IRQ_INTR56,
../arch/m68k/coldfire/device.c:535:35: error: 'MCFEDMA_IRQ_ERR' undeclared here (not in a function)
535 | .start = MCFEDMA_IRQ_ERR,
