Subject[RFC] arm64: dts: use size of reserved partition for bl2
Date
From: Frank Wunderlich <frank-w@public-files.de>

To store uncompressed bl2 more space is required than partition is
actually defined.

I used the definition i got from mtk used in their SDK uboot.

Openwrt uses also the first reserved partition to give bl2 more
space:

https://git.openwrt.org/?p=openwrt/openwrt.git;a=blob;f=target/linux/mediatek/dts/mt7986a-bananapi-bpi-r3-nor.dts;h=f597b869abc80d1a73f44ebb85ad4da17376bb52;hb=HEAD#l22

so imho it should be same in mainline to not require complex bl2
compression.
