Linux-2.6.12-rc2v2.6.12-rc2

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.

Let it rip!

+	bool "MMU support"
+	help
+	  This options switches on and off support for the FR-V MMU

+	  featured MMU.

+	depends on MMU
+	default y
+	help
+	  If you wish to use more than 256MB of memory with your MMU based
+	  system, you will need to select this option. The kernel can only see
+	  the memory between 0xC0000000 and 0xD0000000 directly... everything
+	  else must be kmapped.
+
+	  The arch is, however, capable of supporting up to 3GB of SDRAM.
+
+config HIGHPTE
+	bool "Allocate page tables in highmem"
+	depends on HIGHMEM
+	default y
+	help
+	  The VM uses one page of memory for each page table.  For systems

+	  Setting this option will put user-space page tables in high memory.

+	help
+	  This option sets the base address for the uClinux kernel. The kernel
+	  will rearrange the SDRAM layout to start at this address, and move
+	  itself to start there. It must be greater than 0, and it must be
+	  sufficiently less than 0xE0000000 that the SDRAM does not intersect
+	  the I/O region.
+
+	  The base address must also be aligned such that the SDRAM controller
+	  can decode it. For instance, a 512MB SDRAM bank must be 512MB aligned.

+config PROTECT_KERNEL
+	bool "Protect core kernel against userspace"
+	depends on !MMU
+	default y
+	help
+	  Selecting this option causes the uClinux kernel to change the
+	  permittivity of DAMPR register covering the core kernel image to
+	  prevent userspace accessing the underlying memory directly.
+
+choice
+	prompt "CPU Caching mode"
+	default FRV_DEFL_CACHE_WBACK
+	help
+	  This option determines the default caching mode for the kernel.
+
+	  Write-Back caching mode involves the all reads and writes causing
+	  the affected cacheline to be read into the cache first before being
+	  operated upon. Memory is not then updated by a write until the cache
+	  is filled and a cacheline needs to be displaced from the cache to
+	  make room. Only at that point is it written back.
+
+	  Write-Behind caching is similar to Write-Back caching, except that a
+	  write won't fetch a cacheline into the cache if there isn't already
+	  one there; it will write directly to memory instead.
+
+	  Write-Through caching only fetches cachelines from memory on a
+	  read. Writes always get written directly to memory. If the affected
+	  cacheline is also in cache, it will be updated too.
+
+	  The final option is to turn of caching entirely.
+
+	  Note that not all CPUs support Write-Behind caching. If the CPU on
+	  which the kernel is running doesn't, it'll fall back to Write-Back
+	  caching.

+	prompt "GP-Relative data support"
+	default GPREL_DATA_8
+	help
+	  This option controls what data, if any, should be placed in the GP
+	  relative data sections. Using this means that the compiler can
+	  generate accesses to the data using GR16-relative addressing which
+	  is faster than absolute instructions and saves space (2 instructions
+	  per access).
+
+	  However, the GPREL region is limited in size because the immediate
+	  value used in the load and store instructions is limited to a 12-bit
+	  signed number.
+
+	  So if the linker starts complaining that accesses to GPREL data are
+	  out of range, try changing this option from the default.
+
+	  Note that modules will always be compiled with this feature disabled
+	  as the module data will not be in range of the GP base address.

+	  Some FR-V systems (such as the MB93090-MB00 VDK) have PCI
+	  onboard. If you have one of these boards and you wish to use the PCI
+	  facilities, say Y here.
+
+	  The PCI-HOWTO, available from
+	  <http://www.tldp.org/docs.html#howto>, contains valuable
+	  information about which PCI hardware does work under Linux and which
+	  doesn't.
+
+config RESERVE_DMA_COHERENT
+	bool "Reserve DMA coherent memory"
+	depends on PCI && !MMU
+	default y
+	help
+	  Many PCI drivers require access to uncached memory for DMA device
+	  communications (such as is done with some Ethernet buffer rings). If
+	  a fully featured MMU is available, this can be done through page
+	  table settings, but if not, a region has to be set aside and marked
+	  with a special DAMPR register.
+
+	  Setting this option causes uClinux to set aside a portion of the
+	  available memory for use in this manner. The memory will then be
+	  unavailable for normal kernel use.

+config PCMCIA
+	tristate "Use PCMCIA"
+	help
+	  Say Y here if you want to attach PCMCIA- or PC-cards to your FR-V
+	  board.  These are credit-card size devices such as network cards,
+	  modems or hard drives often used with laptops computers.  There are
+	  actually two varieties of these cards: the older 16 bit PCMCIA cards
+	  and the newer 32 bit CardBus cards.  If you want to use CardBus
+	  cards, you need to say Y here and also to "CardBus support" below.
+
+	  To use your PC-cards, you will need supporting software from David
+	  Hinds pcmcia-cs package (see the file <file:Documentation/Changes>
+	  for location).  Please also read the PCMCIA-HOWTO, available from
+	  <http://www.tldp.org/docs.html#howto>.
+
