| Subject: printk: reduce LOG_BUF_SHIFT range for H8300 |
| |
| From: John Ogness <john.ogness@linutronix.de> |
| |
| [ Upstream commit 550c10d28d21bd82a8bb48debbb27e6ed53262f6 ] |
| |
| The .bss section for the h8300 is relatively small. A value of |
| CONFIG_LOG_BUF_SHIFT that is larger than 19 will create a static |
| printk ringbuffer that is too large. Limit the range appropriately |
| for the H8300. |
