[PATCH v3 21/24] sparc/leon3: Fix to put grlib,* devices on sysbus
Posted by Markus Armbruster 5 years, 8 months ago
leon3_generic_hw_init() creates a "grlib,ahbpnp" and a "grlib,apbpnp"
sysbus device in a way that leaves them unplugged.

Create them the common way that puts them into the main system bus.
Affects machine leon3_generic.  Visible in "info qtree":

     bus: main-system-bus
       type System
    +  dev: grlib,ahbpnp, id ""
    +    mmio 00000000fffff000/0000000000001000
    +  dev: grlib,apbpnp, id ""
    +    mmio 00000000800ff000/0000000000001000
       dev: grlib,irqmp, id ""
