This board is useful for benchmarking overall U-Boot performance. Enable the bootstage feature so we get a report.
Since this returns to the boot rom before finishing executing board_init_r() in SPL, add a few bootstage calls so that we can collect timing from TPL.
For the stash region, use a portion of SRAM, 64KB below the stack top. This allows the TPL image to be up to nearly 120KB (it is typically about 64KB). SPL normally runs from SDRAM at 0, so can use the same stash region.

Building from master commit a1e6b529e57c622e862e93fa6da03d9504565089 and copying u-boot-rockchip.bin to an SD card and booting from that on a RockPRO64 v2.1, I don't get past this: (dirty because building on NixOS applies some patches)

I bisected down to this patch. If I disable CONFIG_BOOTSTATE, I can boot. Is there something I need to do to successfully boot with bootstate enabled?
