Hi,

No, I mean some boards of this model have SoC silkscreen RK3528 and
others have RK3528A. The same is true for another Hinlink H28K SBC.

If you spend a few minutes running mainline u-boot or BSP kernel
on your RK3528 board before blaming me:

BL31:
INFO:    rk_otp_init finish!
INFO:    RK3528 SoC (0x101)

mainline u-boot:
------
U-Boot 2025.07-...

Model: Generic RK3528
SoC:   RK3528A

BSP kernel:

Unless Rockchip says they fused the wrong OTP during production.
Regardless of the SoC silkscreen, the chip type on OTP is the same,
so how does Rockchip distinguish these chips?
