PS2, Line 68: mem_chip_info
should we add some version / size tags, in case if we'll want to change the structure again in the future?

for example u8 entry_size, then we can at least know how to find the next entry correctly.

PS2, Line 70: uint8_t reserved[3];
should we reserve 7 bytes, for 64-bit alignment? or make the structure declared as __attribute__((packed))?
