remove ioremap_nocache and devm_ioremap_nocache

2020-01-06T08:45:59+00:00

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

generic: fix appended dtb support

2019-05-13T19:02:47+00:00

Appended DTB support is mostly intended to be used on legacy systems, but it is a valid feature that can be enabled for generic platform, which currently doesn't support it - if selected, the appended DTB will be ignored by the platform startup code. During kernel startup, the appended DTB's location is stored in fw_passed_dtb if the init code finds what appears to be a valid DTB. Otherwise (if a0 == -2), a1 is stored in fw_passed_dtb, so either way it will always point to either a user-passed DTB or built-in DTB.

MIPS: mscc: add PCB120 to the ocelot fitImage

2018-10-09T17:38:29+00:00

PCB120 and PCB123 are both development boards based on Microsemi Ocelot so let's use the same fitImage for both.

MIPS: kexec: Use prepare method from Generic for UHI platforms

2018-09-22T17:32:34+00:00

Out-of-tree platforms may not be based on Generic as shown in customer communication. Share the prepare method with all using UHI boot protocol, and put into machine_kexec.c. The benefit is that, when having kexec_args related problems, developers will naturally look into machine_kexec.c, where "CONFIG_UHI_BOOT" will be found, prompting them to add "select UHI_BOOT" to the platform Kconfig. It would otherwise require a lot debugging or online searching to be aware that the solution is in Generic code.

MIPS: Remove obsolete MIPS checks for DST node "chosen@0"

2018-08-06T16:50:33+00:00

As there is precious little left in any DTS files referring to the node "/chosen@0" as opposed to "/chosen", remove the two checks for the former node name. [paul.burton@mips.com: The modified yamon-dt code only operates on arch/mips/boot/dts/mti/sead3.dts right now, and that uses chosen rather than chosen@0 anyway, so this should have no behavioural effect.] Signed-off-by: Robert P.

MIPS: generic: fix missing of_node_put()

2018-07-28T02:48:57+00:00

of_find_compatible_node() returns a device_node pointer with refcount incremented and must be decremented explicitly. As this code is using the result only to check presence of the interrupt controller (!NULL) but not actually using the result otherwise the refcount can be decremented here immediately again.

MIPS: generic: remove unnecessary of_platform_populate call

2018-06-24T16:27:27+00:00

The DT core will call of_platform_populate, so it is not necessary for arch specific code to call it unless there are custom match entries, auxdata or parent device. Neither of those apply here, so remove the call.
