This patch unifies sun4i and sun[5,7]i autorefresh setup functions
and adds proper tRFC calculation.
tRFC (REF command to ACT time) depends on DDR type and chip density.
On sun4i there were two steps, 127.5ns for <=1Gb density and 327.5ns
for the rest.
This patch unifies sun4i and sun[5,7]i autorefresh setup functions
and adds proper tRFC calculation.
tRFC (REF command to ACT time) depends on DDR type and chip density.
On sun4i there were two steps, 127.5ns for <=1Gb density and 327.5ns
for the rest. This fits DDR2 specification for 1Gb and 4Gb
