MIPS: OCTEON: Use device tree to probe for flash chips.

Don't assume they are there, the device tree will tell us.

MIPS: OCTEON: Protect accesses to bootbus flash with octeon_bootbus_sem.

Without this, we get bus errors.

mips/octeon: 16-Bit NOR flash was not being detected during boot

2012-11-09T10:37:16+00:00

The cavium code assumed that all NOR on the boot bus was
an 8-bit NOR part and hardcoded the bankwidth. The simple
solution was to add the code that queries the configuration
register for the width of the bus that has been hardware strapped
to the Cavium. This allows both 8-bit and 16-bit parts to be
discovered during boot.

mtd: do not use plain 0 as NULL

2012-03-26T23:53:20+00:00

The first 3 arguments of 'mtd_device_parse_register()' are pointers,
but many callers pass '0' instead of 'NULL'. Fix this globally. Thanks
to coccinelle for making it easy to do with the following semantic patch:

 expression mtd, types, parser_data, parts, nr_parts;

MIPS: Octeon: Fix compile error in arch/mips/cavium-octeon/flash_setup.c

2011-11-10T17:59:45+00:00

The parse_mtd_partitions() and mtd_device_register() functions were
combined into mtd_device_parse_register().  So call that instead.

mips: add export.h to files using EXPORT_SYMBOL/THIS_MODULE

2011-10-31T23:30:57+00:00

Or else we get lots of variations on this:

mtd: octeon: convert to mtd_device_register()

2011-05-25T01:21:11+00:00

Convert to mtd_device_register() and remove the CONFIG_MTD_PARTITIONS
preprocessor conditionals as partitioning is always available.

MIPS: Stop using .

MIPS: Add Cavium OCTEON processor support files to arch/mips/cavium-octeon.

2009-01-11T09:57:21+00:00

These are the rest of the new files needed to add OCTEON processor
support to the Linux kernel.  Other than Makefile and Kconfig which
should be obvious, we have:

csrc-octeon.c   -- Clock source driver for OCTEON.
dma-octeon.c    -- Helper functions for mapping DMA memory.
flash_setup.c   -- Register on-board flash with the MTD subsystem.
octeon-irq.c    -- OCTEON interrupt controller managment.
octeon-memcpy.S -- Optimized memcpy() implementation.
serial.c        -- Register 8250 platform driver and early console.
setup.c         -- Early architecture initialization.
smp.c           -- OCTEON SMP support.
octeon_switch.S -- Scheduler context switch for OCTEON.
c-octeon.c      -- OCTEON cache controller support.
cex-oct.S       -- OCTEON cache exception handler.

asm/mach-cavium-octeon/*.h -- Architecture include files.
