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.
Series-changes: 2
- Rename to rk3399-generic-ddr3
- Update devicetree to match firefly-rk3399
- Use the firefly devicetree as the default for this board
Series-changes: 4
- Drop SPL_PAD_TO value since the default is fine
- Drop ROCKCHIP_IODOMAIN since it is the default
- Add SPL_LIBCOMMON_SUPPORT and SPL_LIBGENERIC_SUPPORT
Series-changes: 5
- Add value for CONFIG_SPL_STACK_R_ADDR
