Hi, You can find it in sys_reg.h. It is described as below.

 * @var SYS_T::PDID
 * Offset: 0x00  Part Device Identification Number Register
 * ---------------------------------------------------------------------------------------------------
 * |Bits    |Field    |Descriptions
 * | :----: | :----:   | :---- |
 * |[31:0]|PDID    |Part Device Identification Number (Read Only)
 * |         |            |This register reflects device part number code. Software can read this register to identify which device is used.

There are no bits description here, only [31:0] = PDID. It does not show how to identify memory size etc.

Yes, the PDID is only for distinguish different chip part number. It doesn't contain the information for memory size.
