Subject: ARM: add debug ".edata_real" symbol
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=dad4675388fcb4353aea64174a165fb8494f1c13;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

ARM: add debug ".edata_real" symbol

Add an additional symbol to the decompressor image, which will allow
future debugging of non-bootable problems similar to the one encountered
with the EFI stub.
