[PATCH v1 2/3] ARM: protonic-stm32mp1: Add support for reading serial from BSEC

[Oleksij Rempel]

From: Michiel Schelfhout <michiel.schelfhout@protonic.nl>

Introduce support for retrieving the board-specific serial number from
BSEC registers via the OP-TEE interface. The serial number is stored
across three 4-byte registers (58, 59, 60), with only the lower 16 bits
of register 58 being relevant.

[PATCH v1 3/3] ARM: protonic-stm32mp1: Add shift register support for board ID and revision

[Oleksij Rempel]

From: Michiel Schelfhout <michiel.schelfhout@protonic.nl>

Introduce support for reading the board ID and hardware revision using a
74HC165BQ shift register.

Since all new designs are expected to include this shift register, support
is enabled by default. Boards that lack the shift register explicitly set
PRT_STM32_NO_SHIFT_REG to skip read of IDs
