The Kconfig currently controlling compilation of this code is:
arch/mips/lantiq/Kconfig:config XRX200_PHY_FW
arch/mips/lantiq/Kconfig: bool "XRX200 PHY firmware loader"...meaning that it currently is not being built as a module by anyone.
Lets remove the couple traces of modular infrastructure use, so that
when reading the driver there is no doubt it is builtin-only.Since module_platform_driver() uses the same init level priority as
builtin_platform_driver() the init ordering remains unchanged with
this commit.Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.
We also delete the MODULE_LICENSE tag etc. since all that information
was (or is now) contained at the top of the file in the comments.We don't replace module.h with init.h since the file doesn't need that.

Instead of rewriting the arguments to match the UHI spec, store the
address of a appended or UHI supplied dtb in fw_supplied_dtb.That way the original bootloader arugments are kept intact while still
making the use of an appended dtb invisible for mach code.Mach code can still find out if it is an appended dtb by comparing
fw_arg1 with fw_supplied_dtb.Signed-off-by: Jonas Gorski

We used the hardware IRQ number to register the IRQ handler and not the
virtual one. This probably caused some problems because the hardware
IRQ numbers are only unique for each IRQ controller and not in the
system. The virtual IRQ number is managed by Linux and unique in the
system. This was probably the reason there was a gab of 8 IRQ numbers added
before the numbers used for the lantiq IRQ controller. With the current
setup the hardware and the virtual IRQ numbers are the same.Reported-by: Thomas Langer

We runtime load the available external interrupts into an array and store
the number inside exin_avail. Some of the code however uses MAX_EIU for
looping over the array which may partially be 0. This is a cosmetic fix as
the existing code works as is. It is just nicer to only loop over the array
elements that were actually populated during probe.Signed-off-by: John Crispin

Using of_irq_count to load the irq index from the devicetree is incorrect.
This will cause the kernel to map them regardless, even if they dont
actually get used. Change the code to use of_property_count_u32_elems()
instead which is the correct API to use in this case.Signed-off-by: John Crispin

Seval of-enabled machines (bmips, lantiq, xlp, pistachio, ralink) copied
the arguments from dtb to arcs_command_line to prevent the kernel from
overwriting them.Since there is now an option to keep the dtb arguments, default to the
new option remove the "backup" to arcs_command_line in case of USE_OF is
enabled, except for those platforms that still take the bootloader
arguments or do not use any at all.Signed-off-by: Jonas Gorski

The majority of SMP platforms handle their IPIs through do_IRQ()
which calls irq_{enter/exit}(). When a call function IPI is received,
smp_call_function_interrupt() is called which also calls
irq_{enter,exit}(), meaning irq_count is raised twice.When tick broadcasting is used (which is implemented via a call
function IPI), this incorrectly causes all CPU idle time on the core
receiving broadcast ticks to be accounted as time spent servicing
IRQs, as account_process_tick() will account as such if irq_count is
greater than 1. This results in 100% CPU usage being reported on a
core which receives its ticks via broadcast.This patch removes the SMP smp_call_function_interrupt() wrapper which
calls irq_{enter,exit}(). Platforms which handle their IPIs through
do_IRQ() now call generic_smp_call_function_interrupt() directly to
avoid incrementing irq_count a second time. Platforms which don't
(loongson, sgi-ip27, sibyte) call generic_smp_call_function_interrupt()
wrapped in irq_{enter,exit}().Signed-off-by: Alex Smith
