MIPS: replace add_memory_region with memblock

2020-10-12T10:01:36Z

add_memory_region was the old interface for registering memory and was already changed to used memblock internaly. Replace it by directly calling memblock functions. Signed-off-by: Thomas Bogendoerfer

MIPS: Only include the platform file needed

2020-05-12T22:17:18Z

Instead of including all Platform files, we simply include the needed one and avoid clashes with makefile variables. Signed-off-by: Thomas Bogendoerfer

MIPS: Replace setup_irq() by request_irq()

2020-03-05T15:47:35Z

request_irq() is preferred over setup_irq(). Invocations of setup_irq() occur after memory allocators are ready. Per tglx[1], setup_irq() existed in olden days when allocators were not ready by the time early interrupts were initialized. Hence replace setup_irq() by request_irq(). remove_irq() has been replaced by free_irq() as well. There were build error's during previous version, couple of which was reported by kbuild test robot of which one was reported by Thomas Bogendoerfer as well. There were a few more issues including build errors, those also have been fixed.

remove ioremap_nocache and devm_ioremap_nocache

2020-01-06T08:45:59Z

ioremap has provided non-cached semantics by default since the Linux 2.6 days, so remove the additional ioremap_nocache interface. Signed-off-by: Christoph Hellwig Acked-by: Arnd Bergmann

PCI: consolidate PCI config entry in drivers/pci

2018-11-23T02:45:34Z

There is no good reason to duplicate the PCI menu in every architecture. Instead provide a selectable HAVE_PCI symbol that indicates availability of PCI support, and a FORCE_PCI symbol to for PCI on and the handle the rest in drivers/pci.

mips: unify prom_putchar() declarations

2018-07-17T16:40:17Z

prom_putchar() is used centrally in early printk infrastructure therefore at least MIPS should agree on the function return type. [paul.burton@mips.com: - Include linux/types.h in asm/setup.h to gain the bool typedef before we start include asm/setup.h elsewhere. - Include asm/setup.h in all files that use or define prom_putchar(). - Also standardise on signed rather than unsigned char argument.] Signed-off-by: Alexander Sverdlin Signed-off-by: Paul Burton Patchwork: https://patchwork.linux-mips.org/patch/19842/ Cc: linux-mips@linux-mips.org Cc: Ralf Baechle Cc: James Hogan Cc: Jonas Gorski Cc: Florian Fainelli Cc: Kate Stewart Cc: Philippe Ombredanne

MIPS: ath25: Check for kzalloc allocation failure

2018-02-23T09:35:54Z

Currently there is no null check on a failed allocation of board_data, and hence a null pointer dereference will occurr. Fix this by checking for the out of memory null pointer.

MIPS: ath25: Avoid undefined early_serial_setup() without SERIAL_8250_CONSOLE

2018-01-10T15:37:28Z

Currently MIPS allnoconfig with CONFIG_ATH25=y fails to link due to missing support for early_serial_setup(): LD vmlinux arch/mips/ath25/devices.o: In function ath25_serial_setup': devices.c:(.init.text+0x68): undefined reference to 'early_serial_setup' Rather than adding dependencies to the platform to force inclusion of SERIAL_8250_CONSOLE together with it's dependencies like TTY, HAS_IOMEM, etc, just make ath25_serial_setup() a no-op when the dependency is not selected in the kernel config.
