Subject: [POWERPC] Fix zImage decompress location
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=c998de146061db17787c1a31a3db1989f1341fdf;p=GitHub%2FLineageOS%2Fandroid_kernel_samsung_universal7580.git

[POWERPC] Fix zImage decompress location

The zImage wrapper has a "hack" that force the decompression to happen
above 20Mb for 64 bits kernels, to work around issues with some
firmwares on the field. However, the new wrapper has a bug which makes
that hack not work properly. This fixes it.
