| Subject: scripts/gdb: change kernel config dumping method |
| |
| From: Kuan-Ying Lee <Kuan-Ying.Lee@mediatek.com> |
| |
| [ Upstream commit 1f7a6cf6b07c74a17343c2559cd5f5018a245961 ] |
| |
| MAGIC_START("IKCFG_ST") and MAGIC_END("IKCFG_ED") are moved out |
| from the kernel_config_data variable. |
| |
| Thus, we parse kernel_config_data directly instead of considering |
| offset of MAGIC_START and MAGIC_END. |
| |
| Fixes: 13610aa908dc ("kernel/configs: use .incbin directive to embed config_data.gz") |
