[Qemu-devel] [PATCH v9 5/9] ARM: exynos4210: Added PMU register model. |
|
Date: |
Fri, 20 Jan 2012 14:53:45 +0400 |
From: Maksim Kozlov <address@hidden>
This model just implements PMU registers as a bulk of memory.
The only reason of existence in such form is that secondary CPU
boot loader uses PMU INFORM5 register as a holding pen.
