MIPS: Loongson: Improve LEFI firmware interface

2014-11-24T06:45:01+00:00

Machtypes of Loongson-3 machines become more and more, but there are
only small differences among different machtypes. Keeping a large table
of machtypes is very ugly and hard to extend. We found that the major
machtype differences are UARTs information (number of UARTs, UART IRQs,
UART clocks, etc.), platform devices (EC, temperature sensors, fan
controllers, etc.) and some workarounds (because of some CPU bugs or
mainboard bugs).

In this patch we improve the UEFI-like (LEFI) interface to make all
Loongson-3 machines use a same machtype "generic-loongson-machine".

MIPS: Loongson 3: Add Lemote-3A machtypes definition

2014-03-31T16:17:12+00:00

Add four Loongson-3 based machine types:
MACH_LEMOTE_A1004/MACH_LEMOTE_A1201 are laptops;
MACH_LEMOTE_A1101 is mini-itx;
MACH_LEMOTE_A1205 is all-in-one machine.

The most significant differrent between A1004/A1201 and A1101/A1205 is
the laptops have EC but others don't.

MIPS: mm: init: Add free_init_pages() callback for EVA

2014-03-26T22:09:18+00:00

A core in EVA mode can have any possible segment mapping, so the
default free_initmem_default() function may not always work as expected.
Therefore, add a callback that platforms can use to free up the init section.

MIPS: add detect_memory_region()

2013-05-07T23:19:11+00:00

Add a generic way of detecting the available RAM. This function is based on the
implementation already used by ath79.

MIPS: Whitespace cleanup.

2013-02-01T09:00:22+00:00

Having received another series of whitespace patches I decided to do this
once and for all rather than dealing with this kind of patches trickling
in forever.

MIPS: Handle initmem in systems with kernel not in add_memory_region() mem

2011-12-07T22:03:45+00:00

This patch addresses a couple of related problems:

1) The kernel may reside in physical memory outside of the ranges set
   by plat_mem_setup().  If this is the case, init mem cannot be
   reused as it resides outside of the range of pages that the kernel
   memory allocators control.

2) initrd images might be loaded in physical memory outside of the
   ranges set by plat_mem_setup().  The memory likewise cannot be
   reused.  The patch doesn't handle this specific case, but the
   infrastructure is useful for future patches that do.

The crux of the problem is that there are memory regions that need be
memory_present(), but that cannot be free_bootmem() at the time of
arch_mem_init().  We create a new type of memory (BOOT_MEM_INIT_RAM)
for use with add_memory_region().  Then arch_mem_init() adds the init
mem with this type if the init mem is not already covered by existing
ranges.

When memory is being freed into the bootmem allocator, we skip the
BOOT_MEM_INIT_RAM ranges so they are not clobbered, but we do signal
them as memory_present().  This way when they are later freed, the
necessary memory manager structures have initialized and the Sparse
allocater is prevented from crashing.

The Octeon specific code that handled this case is removed, because
the new general purpose code handles the case.
