[Xen-devel] [PATCH v2 26/35] xen/arm32: head: Rework and document zero_bss()

2019-07-22 Thread Julien Grall
On secondary CPUs, zero_bss() will be a NOP because BSS only need to be zeroed once at boot. So the call in the secondary CPUs path can be removed. Lastly, document the behavior and the main registers usage within the function. Signed-off-by: Julien Grall --- Changes in v2: - Patch
