mentioned this 48 bit customer id a while ago being the the preempt to the bootldr you have to read the SPI locations listed below

hope you read this

Start reading from page 85
It also states where to read the chip id
The Read Serial Number Registers rd_serial_num0 and rd_serial_num1 contain 48 bits of customer ID data
provided by the customer. The 48 bits are spread across the two registers. Address x‘000A’ contains the
most significant 32 bits, and address x‘000B’ contains the least significant 16-bits. This pair of registers
contains the same data as the serial_number MMIO register. The data in these registers is only valid after the
POR sequence has completed because these registers are loaded from the configuration ring
