powerpc/32: Remove wii_memory_fixups()

2022-09-01T03:56:07Z

wii_memory_fixups() is not called anymore, remove it. Also remove left-overs in mmu_decl.h which were forgotten by commit 160985f3025b ("powerpc/wii: remove wii_mmu_mapin_mem2()") Signed-off-by: Christophe Leroy Signed-off-by: Michael Ellerman Link: https://lore.kernel.org/r/5f2091f86528b59ef92ef1daed5d3dd8c0d7bebd.1661938317.git.christophe.leroy@csgroup.eu

powerpc: Add missing headers

2022-05-08T12:15:40Z

Don't inherit headers "by chances" from asm/prom.h, asm/mpc52xx.h, asm/pci.h etc... Include the needed headers, and remove asm/prom.h when it was needed exclusively for pulling necessary headers.

2022-05-08T12:15:04Z

Several files include asm/prom.h for no reason. Clean it up.

powerpc/embedded6xx: Add __init attribute to eligible functions

2021-12-23T11:33:17Z

Some functions defined in 'arch/powerpc/platforms/embedded6xx' are deserving of an `__init` macro attribute. These functions are only called by other initialization functions and therefore should inherit the attribute. Also, change function declarations in header files to include `__init`.

powerpc: Rename PPC_NATIVE to PPC_HASH_MMU_NATIVE

2021-12-02T11:57:22Z

PPC_NATIVE now only controls the native HPT code, so rename it to be more descriptive. Restrict it to Book3S only. Signed-off-by: Nicholas Piggin Signed-off-by: Michael Ellerman Link: https://lore.kernel.org/r/20211201144153.2456614-3-npiggin@gmail.com

powerpc/6xx: add missing of_node_put

2021-11-25T00:25:29Z

for_each_compatible_node performs an of_node_get on each iteration, so a break out of the loop requires an of_node_put. A simplified version of the semantic patch that fixes this problem is as follows (http://coccinelle.lip6.fr): // @@ expression e; local idexpression n; @@ @@ local idexpression n; expression e; @@ for_each_compatible_node(n,...) { ... ( of_node_put(n); | e = n | + of_node_put(n); ? break; ) ... } ... when != n // Signed-off-by: Julia Lawall Signed-off-by: Michael Ellerman Link: https://lore.kernel.org/r/1448051604-25256-2-git-send-email-Julia.Lawall@lip6.fr

powerpc: Refactor verification of MSR_RI

2021-08-26T11:21:07Z

40x and BOOKE don't have MSR_RI therefore all tests involving MSR_RI may be problematic on those plateforms. Create helpers to check or set MSR_RI in regs, and use them in common code.

powerpc: Bulk conversion to generic_handle_domain_irq()

2021-08-10T13:15:02Z

Wherever possible, replace constructs that match either generic_handle_irq(irq_find_mapping()) or generic_handle_irq(irq_linear_revmap()) to a single call to generic_handle_domain_irq().
