mtd: bcm63xxpart: give width specifier an 'int', not 'size_t'

2016-03-07T21:13:58+00:00

Fixes this warning:

       pr_err("invalid rootfs address: %*ph\n",
       ^
>> include/linux/kern_levels.h:4:18: warning: field width specifier '*' expects argument of type 'int', but argument 2 has type 'long unsigned int' [-Wformat=]

mtd: bcm63xxpart: Move NOR flash layout to a separate function

2016-02-12T18:34:16+00:00

Move the NOR flash layout to a separate function to allow the NAND flash
layout to be supported.

mtd: bcm63xxpart: Null terminate and validate conversion of flash strings

2016-02-12T18:34:16+00:00

Strings read from flash could be missing null termination characters, or
not contain valid integers.

Null terminate the strings and check for errors when converting them to
integers.

Also validate that the addresses are at least BCM963XX_EXTENDED_SIZE
because this will be subtracted from them.

mtd: bcm63xxpart: Remove dependency on mach-bcm63xx

2016-02-12T18:27:48+00:00

Read nvram directly from flash instead of using the in-memory copy that
mach-bcm63xx has, to remove the dependency on mach-bcm63xx and allow the
parser to work on bmips too.

Rename remaining BCM63XX defines to BCM963XX as these are properties of
the flash layout on the board.

BCM963XX_DEFAULT_PSI_SIZE changes from SZ_64K to 64 because it will be
multiplied by SZ_1K later on.

Merge branch 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus

2016-01-24T20:50:56+00:00

Pull MIPS updates from Ralf Baechle:
 "This is the main pull request for MIPS for 4.5 plus some 4.4 fixes.

  The executive summary:

   - ATH79 platform improvments, use DT bindings for the ATH79 USB PHY.
   - Avoid useless rebuilds for zboot.
   - jz4780: Add NEMC, BCH and NAND device tree nodes
   - Initial support for the MicroChip's DT platform.  As all the device
     drivers are missing this is still of limited use.
   - Some Loongson3 cleanups.
   - The unavoidable whitespace polishing.
   - Reduce clock skew when synchronizing the CPU cycle counters on CPU
     startup.
   - Add MIPS R6 fixes.
   - Lots of cleanups across arch/mips as fallout from KVM.
   - Lots of minor fixes and changes for IEEE 754-2008 support to the
     FPU emulator / fp-assist software.
   - Minor Ralink, BCM47xx and bcm963xx platform support improvments.
   - Support SMP on BCM63168"

MIPS: bcm963xx: Move extended flash address to bcm_tag header file

2016-01-24T02:48:43+00:00

The extended flash address needs to be subtracted from bcm_tag flash
image offsets. Move this value to the bcm_tag header file.

Renamed define name to consistently use bcm963xx for flash layout
which should be considered a property of the board and not the SoC
(i.e. bcm63xx could theoretically be used on a board without CFE
or any flash).

mtd: partitions: make parsers return 'const' partition arrays

2015-12-09T18:21:57+00:00

We only want to modify these arrays inside the parser "drivers", so the
drivers should construct them however they like, then return them as
immutable arrays.

This will make other refactorings easier.

mtd: kill off MTD partition parser boilerplate

2015-11-20T02:46:29+00:00

Most parsers can be handled with our new boilerplate-reducing macro.
There are a few that can't be (cmdlineparts and ofpart).

Also kill off the owner assignments, since register_mtd_parser() now
takes care of that.
