[U-Boot] [PATCH v2 12/17] ram: rk3328: use common sdram driver

Kever Yang kever.yang at rock-chips.com
Fri Oct 25 01:33:59 UTC 2019


From: YouMin Chen <cym at rock-chips.com>

RK3328 has a similar controller and phy with PX30, so we can use the
common driver for it and remove the duplicate codes.
