[PATCH 25/29] rockchip: Add a generic rk3399 board

Wed Feb 5 02:55:15 CET 2025

This build-target is used to build an image which can run on multiple
rk3399 boards, using VBE to boot.

To use it, the TPL binary for a particular board must be placed into the
first part of the image. The rest of the image (i.e. VPL, SPL and
U-Boot) are largely generic and can work on any supported board.

With VBE, memory-init happens in SPL so that this code is updatable in
the field. Due to size constraints, the type of memory on the board is
defined at build-time. So it is not possible to use the same VBE image
on boards with different SDRAM (DDR3 vs LPDDR4 for example). This may
become possible with newer boards with more SRAM.
