Subject: [PATCH 1/2] board: tbs2910: Use recommended distroboot addresses
Date: Thu, 27 Aug 2020 21:52:46 +0200 [thread overview]
Message-ID: <20200827195247.25917-1-smoch@web.de> (raw)
According to doc/README.distro fdt_addr must not be set when DTB is not
available from hardware. So remove this entry.
Use address 32MB above the start of DRAM for kernel_addr_r. This way
we likely can avoid the self-relocation of the compressed kernel image
before it decompresses to offset 0x8000 from start of DRAM.
Use address 128MB above the start of DRAM for fdt_addr_r, since this is
the maximum location for the end of the kernel. So we avoid overwriting
the DTB.
Use 512k above that for ramdisk_addr_r. This should be enough for the
DTB, rest of DRAM can be used for initrd.
Place boot script / extlinux.conf at offset 0 / 1MB from start of DRAM.
This space is available for processing in U-Boot.

Recommendations taken from [1].
Distroboot support for the tbs2910 board was added in the v2020.10
merge window. So please pull this in as fix for v2020.10.
Thanks,
Soeren
