To store uncompressed bl2 more space is required than partition is actually defined.
There is currently no known usage of this reserved partition. Openwrt uses same partition layout.
We added same change to u-boot with commit d7bb1099 [1].

My current bl2 is 197K for nor and i ran into this problem.
Openwrt uses also the first reserved partition to give bl2 more space:
https://git.openwrt.org/?p=openwrt/openwrt.git%3Ba=blob%3Bf=target/linux/med...
so imho it should be same in mainline to not require complex bl2 compression.
have now sent the board-specific dts to uboot too: https://source.denx.de/u-boot/u-boot/-/commit/d7bb109900c1ca754a0198b9afb50e... --- .../boot/dts/mediatek/mt7986a-bananapi-bpi-r3-nor.dtso | 7 +------ 1 file changed, 1 insertion(+), 6 deletions(-)

Since you're not changing the start address for the first partition, but only extending it, this will not break anything, so

Applied, thanks!
If the bl2 does not fit into the bl2-partition (cut off), board does not boot, thats why i want to increase it now. My current bl2 is 197K for nor and i ran into this problem.
