u-boot-rockpro64: implement workaround for A72 errata #859971

This disables i-cache prefetch, which can otherwise cause deadlocks on the
processor revision that ROCKPro64 uses.
Done via binary patch of the Rockchip TF-A EL3 firmware.

Bump PKGREVISION.

Log message:
u-boot-rock{,pro}64: move PKGREVISION from common Makefile to per-package

Log message:
u-boot-rock{,pro}64: install the SPI boot loader. Bump.

Log message:
u-boot-rock*: update to latest ayufan release & rockchip DDR firmware

No convenient changelog available.

Note: due to upstream changes in EFI device enumeration, implicit boot device
selection no longer works from the NetBSD EFI boot loader. e.g. "boot \ 
netbsd"
doesn't work. Specify the device explicitly, e.g. "boot hd0a:netbsd".

Log message:
update rock*64 u-boot to the latest (1060-g56bd958253) from ayufan.

tested on rock64, works with rock64 v3.

Log message:
update pine64's rockpro64 to latest version from ayufan.

add u-boot package for rock64.  originally this was the same
as the old rockpro64 and works fine on that the rev2.0 board,
but didn't on rev3.0.  the updated version is still has a
problem, but at least gets further and has partition issues
instead of failing to talk to the sd at all.  share a bunch
of the makefile with rockpro64.

for all u-boot, properly fix the subst for tools/dtoc/dtoc.

add both rock64 and rockpro64 to the u-boot meta package and
bump the pkg revision.

U-Boot is a bootloader for embedded boards based on PowerPC, ARM, MIPS and
several other processors, which can be installed in a boot ROM and used to
initialize and test the hardware or to download and run application code.

This package provides U-Boot for the rk3389-based RockPRO64 from PINE64.
