Here is my updated patch to fix buffered flash writes on the VExpress platform. Buffered writes should now work properly on platforms whose flash interface width is different from the device width. The default is for the device-width to be set to the interface width, so platforms that can benefit from this change will need to be updated. This patchset updates the configuration for the VExpress platform which requires it. UEFI firmware uses buffered writes for persistent variable storage, and this patchset enables this usage on QEMU.
Changes from v1: * Add device-width property and use this to mask write length instead of devices mas write length * Update vexpress init code to set device-width to proper value.
