This series completes the work to enable VBE on a suitable board. Most
of it is rockchip-specific patches to support the VPL phase, i.e. the
one which decides which boot patch to take (A, B or recovery).
A good chunk of this series is adding an image for VBE, by creating a
new Binman image. Future work in Binman may make this more automated /
easier, but for now it is written out in full. The work is undertaken
piecemeal so it is easier to review the steps.
VBE allows similar boards to share firmware images, with perhaps just
TPL (around 75K) being different for each board. Using a common image
for VPL, SPL and U-Boot saves a lot of space in the image and makes
builds easier. Of course, each board still needs a separate devicetree.
Here is the layout of the image:

This series still bloblist reverts and changes, just so that the boar
doesn't hang on boot. I have already sent a series to resolve this, but
so far it has been rejected:
https://patchwork.ozlabs.org/project/uboot/list/?series=456263&state=*
This is (mostly) the final VBE series, but there are a few loose ends to
tidy up:
- cache is disabled in SPL, which slows the boot a little
- pinctrl init needs to be tidied up to avoid warnings
- bloblist logic as above
- bloblist-relocation is partly in board-specific code, partly generic
Other things may become apparently after more usage / testing.
Changes in v4:
- Use FIT_ARCH instead of ARCH
- Use FIT_ARCH instead of ARCH
- Use FIT_ARCH instead of ARCH
- Use fit_template instead of common_part
- Put the fdtmap at the end of the image
- Update the comment at the end of the '#ifndef CONFIG_VPL' block
- Add a value for SPL_STACK_R_ADDR
- 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
- Fix 'an' typo in commit subject
- Rebase to -next
Changes in v3:
- Add blank lines before the node
- Add a comment about the offsets
- Move template to the vpl file
- Add the BLOBLIST_RELOC condition as well
Changes in v2:
- Move VPL things into a separate file
- Move VPL things into a separate file
- Move VPL things into a separate file
- Mention RK3399 with respect to the memory limit
- Move VPL things into a separate file
- Only enable MMC when VPM is in use.
- Rewrite help for VPL_ROCKCHIP_COMMON_BOARD
- Skip spl-boot-order.c for VPL (rather than modifying it)
- Reword commit to mention comments from Jonas
- Rename to rk3399-generic-ddr3
- Update devicetree to match firefly-rk3399
- Use the firefly devicetree as the default for this board
- Move this patch to the end of the series
- Drop 0x8000 offset for SPI
- Add new patch with a bootmeth driver for abrec
- Split out the fixes for skip-at-start into a new patch
- Move this logic into board-specific code
- Move the actual relocation code to a previous board-specific patch
