[U-Boot] rockchip: rk3399: TPL: rockpro64: Wrong memory size detected【请注意，邮件由u-boot-bounces at lists.denx.de代发】 detected

[Kever Yang]

Hi Jagan,

     Seems like your and Kurt's board have different DRAM type:

- 16bit row + 1 CS

- 15bit row + 2 CS

Capacity detect function is missing for the driver now, and it's not able

to detect the correct size like Kurt is using.


Thanks,

- Kever
