e1000's #define of CONFIG_RAM_BASE conflicts with a Kconfig symbol in arch/csky/Kconfig. The symbol in e1000 has been around longer, so change arch/csky/ to use DRAM_BASE instead of RAM_BASE to remove the conflict. (although e1000 is also a 2-line change)

IMO "CONFIG_" namespace should belong to Kconfig files, not individual drivers, but e1000 isn't the only driver that uses CONFIG_ symbols. arch/csky/Kconfig | 2 +- arch/csky/include/asm/page.h | 2 +- 2 files changed, 2 insertions(+), 2 deletions(-) --- linux-next-20210409.orig/arch/csky/include/asm/page.h +++ linux-next-20210409/arch/csky/include/asm/page.h @@ -28,7 +28,7 @@ #define SSEG_SIZE 0x20000000 #define LOWMEM_LIMIT (SSEG_SIZE * 2) -#define PHYS_OFFSET_OFFSET (CONFIG_RAM_BASE & (SSEG_SIZE - 1)) +#define PHYS_OFFSET_OFFSET (CONFIG_DRAM_BASE & (SSEG_SIZE - 1)) #ifndef __ASSEMBLY__ --- linux-next-20210409.orig/arch/csky/Kconfig +++ linux-next-20210409/arch/csky/Kconfig @@ -314,7 +314,7 @@ config FORCE_MAX_ZONEORDER int "Maximum zone order" default "11" -config RAM_BASE +config DRAM_BASE hex "DRAM start addr (the same with memory-section in dts)" default 0x0
