[PATCH RESEND] csky: change a Kconfig symbol name to fix e1000 build error

From: Randy Dunlap
Date: Sun Apr 11 2021 - 02:04:04 EST


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)

Now build-tested.

Andrew, please merge.

v2: Add Acked-by: Guo Ren
Has now been build-tested.

IMO "CONFIG_" namespace should belong to Kconfig files, not
individual drivers, but e1000 isn't the only driver that uses
CONFIG_ symbols.
