plat: kendryte/k210: Enable fw_payload in config.mk
We can only use fw_payload blob on Kendryte K210 board
because there is no previous booting stage hence this
patch enables fw_payload for Kendryte K210 board.

blob: payload: Add FW_PAYLOAD_FDT_PATH option
This patch extends fw_payload blob to provide FW_PAYLOAD_FDT_PATH
option using which we can embed custom FDT in .text section of
fw_payload blob. In other words, FW_PAYLOAD_FDT_PATH is an option
to forcefully override FDT passed by previous booting stage in
a1 register.

blob: Rename FW_xyz_FDT_OFFSET to FW_xyz_FDT_ADDR
Instead of placing FDT (passed by previous booting stage) at a
location relative to next address we should have absolute
location of placing FDT so that we more freedom of placing FDT.
This will be particularly useful for platforms/boards with
very less RAM (such as Kendryte board).
Due to above motivation, we rename FW_xyz_FDT_OFFSET options
to FW_xyz_FDT_ADDR options and use FW_xyz_FDT_ADDR options as
absolute address for placing FDT.

This patch remove hard-coding of payload location in
fw_payload.elf.ldS by adding compile-time option
FW_PAYLOAD_OFFSET.
With the new compile-time option, payload will be placed
at PLAT_TEXT_START + FW_PAYLOAD_OFFSET address.

plat: clint: Reduce use of atomic operation on IPI registers
Currently, we aggresively use atomic operation on CLINT IPI
register. This patch simplify CLINT IPI APIs by reducing use
of atomic operations. In future, we will gradually increase
use of atomic operations for CLINT IPI APIs.
