[edk2] [PATCH 0/3] ArmVirtPkg: ignore DT nodes with a status != 'okay'
Posted by Ard Biesheuvel 6 years, 11 months ago
The DT passed to us by QEMU may contain nodes that are supposed to be
consumed by the secure world only. In some case, their status may be
set to 'secure', but 'disabled' occurs as well, if the secure OS has
actually modified the DT.

Since as a general rule, DT nodes should only be consumed if they lack a
status or if their status equals 'okay', update our DT node parsing
routines accordingly.

Ard Biesheuvel (3):
  ArmVirtPkg/FdtClientDxe: take DT memory node 'status' property into
    account
  ArmVirtPkg/FdtPL011SerialPortLib: take DT node 'status' property into
    account
  ArmVirtPkg/PlatformPeiLib: take DT node 'status' property into account

Please re-wrap commit messages #2 and #3 to a width of 74 characters.

The subject lines are also too long (on patches #1 and #2); please come
up with alternatives that fit into 74 characters. For example, replace

  take DT xxx node 'status' property into account

with

  honor DT xxx node 'status' property

With that, series
