[PATCH 0/5] hw/riscv: more FDT cleanups (PLIC)

Posted by Daniel Henrique Barboza 1 month, 1 week ago

Hello,

Here is the follow-up I talked about in the first FDT series that was
just merged [1].  This short series handles just the PLIC controller
FDT.  This time there are 2 FDT bug fixes in the mix (patches 3 and 4)
that we were lucky to find.

Expected changes after this series are related to patches 3 and 4 only:

 $ diff virt.dts virt_patch.dts
 189c189
 <               rng-seed = (...) 
 ---
 >               rng-seed = (...) 
 285c285
 <               plic@c000000 {
 ---
 >               interrupt-controller@c000000 {
 297c297
 <               plic@c600000 {
 ---
 >               interrupt-controller@c600000 {

$ diff sifive.dts sifive_patch.dts
 >                       #address-cells = <0x00>;


Patches based on master.
