Rockchip defines the expected layout/map of the default storage device. Fill out the wks description so it matches.https://opensource.rock-chips.com/wiki_Partitions There are 2 partitions at the start that can not be specified in rockchip.wks due to a limitation in wic which assumes all sizes (e.g. --size or --fixed-size) are specified in units of 1024 bytes. Due to the fact these partitions don't fall on 1024-byte boundaries, they can not be specified at this time. Note: in the Rockchip layout, not all partitions are expected to show up in the gpt partition table. This patch uses "--no-table" to only number the partitions that are numbered in the Rockchip wiki, as well as to give these partitions the partition numbers indicated in the wiki. Note: there is a mistake in the Rockchip table (which I've copied verbatim here in this commit message but corrected in rockchip.wks). Going by the values of the "Start Sector", the size of the "reserved1" partition is listed as being 2x its actual size/number of sectors.

I would have kept this one and...
+part uboot_env --offset 8128s --fixed-size 32K --fstype=none --no-table +part reserved2 --offset 8192s --fixed-size 4096K --fstype=none --no-table
this one in the table to keep the offsets identical before and after this patch is applied.
If you don't care about this, then I strongly suggest to have uboot_env actually a partition (and maybe v_storage as well), those partitions are the only ones among the one removed now that would make some sense to me to expose to the user.
Cheers, Quentin
