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
