powerpc: Cleanup idle for e500

2022-09-26T13:00:14Z

e500 idle setup is a bit messy. e500_idle() is used for PPC32 while book3e_idle() is used for PPC64. As they are mutually exclusive, call them all e500_idle(). Use CONFIG_MPC_85xx instead of PPC32 + E500 in Makefile and rename idle_e500.c to idle_85xx.c . Rename idle_book3e.c to idle_64e.c and remove #ifdef PPC64 in as it's only built on PPC64.

powerpc: Remove redundant selection of E500 and E500MC

2022-09-26T13:00:13Z

PPC_85xx and PPC_BOOK3E_64 already select E500 so no need to select it again by PPC_QEMU_E500 and CORENET_GENERIC as they depend on PPC_85xx || PPC_BOOK3E_64. PPC_BOOK3E_64 already selects E500MC so no need to select it again by PPC_QEMU_E500 if PPC64, PPC_BOOK3E_64 is the only way into PPC_QEMU_E500 with PPC64.

powerpc: Remove CONFIG_PPC_BOOK3E

2022-09-26T13:00:13Z

CONFIG_PPC_BOOK3E is redundant with CONFIG_PPC_BOOK3E_64. The later is more explicit about the fact that it's a 64 bits target. Remove CONFIG_PPC_BOOK3E.

powerpc/85xx: Add missing of_node_get/put() in ge_imp3a_pci_assign_primary()

2022-09-05T07:30:29Z

for_each_node_by_type() will automatically increase and decrease the refcount during the iteration. However, there is a reference escaped into global 'fsl_pci_primary' and we need to handle it.
