This series allows rpi to boot a compressed Ubuntu kernel with ~100MB
ramdisk, by expanding the available space.
It also tidies up some strange behaviour with the provided FDT, where a
separate pointer is maintained to it, even though U-Boot has copied it
and placed it in its own space. This avoids strange bugs where it
accidentally gets overwritten when loading a file into memory.
The patch to expand the devicetree was dropped, meaning that people
should be careful to unset fdt_addr in the environment.
In version 2, it incorporates some changes to fdt_addr, etc. suggested
by Tom, as well as adding myself as a maintainer.
Changes in v4:
- Expand the comment on set_fdt_addr()
- Update the commit message to talk in terms of my testing
Changes in v3:
- Add to the existing comment block
- Update the comment block with the new values, including compression
Changes in v2:
- Add new patch to make myself an rpi maintainer
- Add new patch to set bootm_size
- Add new patch to drop fdt_high and initrd_high
- Drop patch to allow expanding the devicetree during relocation
Simon Glass (5):
rpi: Add myself to the list of maintainers
rpi: Set bootm_size to 512MB
rpi: Drop fdt_high and initrd_high
rpi: Update environment to support booti and large initrd
rpi: Use the U-Boot control FDT for fdt_addr
