[Qemu-arm] [PATCH 01/19] loader: Add new load_ramdisk_as() |
Date: |
Tue, 20 Feb 2018 18:03:07 +0000 |
Add a function load_ramdisk_as() which behaves like the existing
load_ramdisk() but allows the caller to specify the AddressSpace
to use. This matches the pattern we have already for various
other loader functions.
