MIPS: Alchemy: Fix missing prototypes

2024-01-22T09:32:36+00:00

We have a number of missing prototypes warnings for board_setup(),
alchemy_set_lpj() and prom_init_cmdline(), prom_getenv() and
prom_get_ethernet_addr(). Fix those by providing definitions for the
first two functions in au1000.h which is included everywhere relevant,
and including prom.h for the last three.

driver core: lift dma_default_coherent into common code

2021-02-13T08:51:45+00:00

Lift the dma_default_coherent variable from the mips architecture code
to the driver core.  This allows an architecture to sdefault all device
to be DMA coherent at run time, even if the kernel is build with support
for DMA noncoherent device.  By allowing device_initialize to set the
->dma_coherent field to this default the amount of arch hooks required
for this behavior can be greatly reduced.

MIPS: refactor the runtime coherent vs noncoherent DMA indicators

2021-02-13T08:51:45+00:00

Replace the global coherentio enum, and the hw_coherentio (fake) boolean
variables with a single boolean dma_default_coherent flag.

MIPS/alchemy: factor out the DMA coherent setup

2021-02-13T08:51:45+00:00

Factor out a alchemy_dma_coherent helper that determines if the platform
is DMA coherent.  Also stop initializing the hw_coherentio variable, given
that is only ever set to a non-zero value by the malta setup code.

MIPS: alchemy: Fix build error after ioremap cleanup

2020-04-20T11:31:38+00:00

IOremap changes caused following build error:

+‘remap_pfn_range’; did you mean ‘io_remap_pfn_range’?
+[-Werror=implicit-function-declaration]

Fixed my including linux/mm.h

MIPS: cleanup fixup_bigphys_addr handling

2020-04-19T14:09:44+00:00

fixup_bigphys_addr is only provided by the alchemy platform.  Remove
all the stubs, and ensure we only call it if it is actually implemented.

Also don't bother implementing io_remap_pfn_range if we don't have to,
and move the remaining implementation to alchemy platform code.

MIPS: Sanitise coherentio semantics

2016-10-06T16:01:28+00:00

The coherentio variable has previously been used as a boolean value,
indicating whether the user specified that coherent I/O should be
enabled or disabled. It failed to take into account the case where the
user does not specify any preference, in which case it makes sense that
we should default to coherent I/O if the hardware supports it
(hw_coherentio is non-zero).

Introduce an enum to clarify the 3 different values of coherentio & use
it throughout the code, modifying plat_device_is_coherent() &
r4k_cache_init() to take into account the default case.

MIPS: Alchemy: remove declaration for set_cpuspec

2015-02-20T12:00:45+00:00

set_cpuspec() has been dropped with commit 074cf656700ddd1d2bd7f815f78e785418beb898
("MIPS: Alchemy: remove cpu_table.") in late 2008.
