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.]

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: mscc: build FIT image for Ocelot

2018-07-25T00:42:19+00:00

Ocelot now has a u-boot port, allow building FIT images instead of relying
on the legacy detection and builtin DTB.

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.

MIPS: xilfpga: Actually include FDT in fitImage

and its.S file for xilfpga but forgot to add it to

MIPS: Generic: Support GIC in EIC mode

2018-02-05T14:36:03+00:00

The GIC supports running in External Interrupt Controller (EIC) mode,
and will signal this via cpu_has_veic if enabled in hardware. Currently
the generic kernel will panic if cpu_has_veic is set - but the GIC can
legitimately set this flag if either configured to boot in EIC mode, or
if the GIC driver enables this mode. Make the kernel not panic in this
case, and instead just check if the GIC is present. If so, use it's CPU
local interrupt routing functions. If an EIC is present, but it is not
the GIC, then the kernel does not know how to get the VIRQ for the CPU
local interrupts and should panic. Support for alternative EICs being
present is needed here for the generic kernel to support them.
