[yocto] [meta-raspberrypi][PATCH 0/6] Drop rpi-mkimage and use upstream u-boot

[Paul Barker]

Following discussion on the Raspberry Pi tools bug tracker it was found that
rpi-mkimage is no longer needed with recent firmware. It can therefore be
dropped from the layer completely.

Whilst looking into this I also found that the u-boot-rpi recipe in
meta-raspberrypi can now be replaced by direct use of the mainline u-boot recipe
from oe-core. The 2016.03 release of u-boot supports the original Raspberry Pi
and the Raspberry Pi 2. Configuration of the u-boot environment to directly boot
the uImage file on the SD card must still be done manually - I'm going to look
into making this work by default in the near future.

Build and boot tested on an old Raspberry Pi Model B (rev 2):
* linux-raspberrypi 4.1
* linux-raspberrypi 4.4
* u-boot 2016.03 + linux-raspberrypi 4.1

U-boot commands needed for my board (the dtb at least may need to change for
other models):
    setenv fdtfile bcm2807-rpi-b.dtb
    setenv bootargs 'earlyprintk console=tty0 console=ttyAMA0 root=/dev/mmcblk0p2 rootfstype=ext4 rootwait noinitrd'
    setenv do_load_files 'mmc dev 0; fatload mmc 0:1 ${kernel_addr_r} uImage; fatload mmc 0:1 ${fdt_addr_r} ${fdtfile};'
    setenv do_boot_files 'bootm ${kernel_addr_r} - ${fdt_addr_r};'
    setenv bootcmd 'run do_load_files do_boot_files'
    saveenv
    boot

During testing it was found that linux-raspberrypi 3.18 no longer builds and so
this was dropped from the layer.

Paul Barker (6):
  linux-raspberrypi: Allow override of PV
  linux-raspberrypi: rpi-mkimage is no longer needed
  u-boot: Use mainline u-boot recipe from oe-core
  rpi-mkimage: Remove unused recipe
  linux-raspberrypi: Drop version 3.18
  sdcard_image-rpi: Always install dtb files
