This series allows rpi to boot a compressed Ubuntu kernel with ~100MB ramdisk, by expanding the available space.
What version of the RPi hardware have you tested this on?
Only rpi_4 and rpi_5
The U-Boot change itself is tested on rpi_0 and rpi_2 but not actually booting a kernel[1]. I don't seem to have an rpi_1 in my lab.
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.
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
