[U-Boot] [PATCH v2 12/12] 83xx: Add support for fsl_dma driver

[Stefan Roese <sr@denx.de>]

Hi Peter,

this patch breaks some PPC4xx boards. Those enabling CONFIG_DDR_ECC, e.g. 
canyonlands:

[stefan at stefan-desktop u-boot-ppc4xx (master)]$ ./MAKEALL canyonlands
Configuring for canyonlands board...
fsl_dma.c:50:2: error: #error "Freescale DMA engine not supported on your 
processor"
make[1]: *** No rule to make target `.depend', needed by `libdma.a'.  Stop.

The #if construct doesn't seem to work for all PPC boards. I have to admit 
that I don't understand the logic enabling the CONFIG_FSL_DMA define. It would 
be great if you (or somebody else with the FSL insight) could fix this.

Thanks.

Best regards,
Stefan
