Subject: bcm47xx: relocate LZMA loader
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=4cd97e4760899172a1d6339ea5644992775e504e;p=openwrt%2Fstaging%2Fxback.git

bcm47xx: relocate LZMA loader

Kernel 5.10 grew bigger than 5.4 so we need to bump BZ_TEXT_START to
allow lzma loader hanel its size.

At the same time BZ_STACK_START needs to be increased to avoid
overwriting the stack.

For a reference see:
