* Compact Flash
The Cavium Compact Flash device is connected to the Octeon Boot Bus,
and is thus a child of the Boot Bus device. It can read and write
industry standard compact flash devices.
Properties:
- compatible: "cavium,ebt3000-compact-flash";
Compatibility with many Cavium evaluation boards.
- reg: The base address of the the CF chip select banks. Depending on
the device configuration, there may be one or two banks.
- cavium,bus-width: The width of the connection to the CF devices. Valid
values are 8 and 16.
- cavium,true-ide: Optional, if present the CF connection is in True IDE mode.
- cavium,dma-engine-handle: Optional, a phandle for the DMA Engine connected
to this device.
Example:
compact-flash@5,0 {
compatible = "cavium,ebt3000-compact-flash";
reg = <5 0 0x10000>, <6 0 0x10000>;
cavium,bus-width = <16>;

* Spec
*
* memcpy copies len bytes from src to dst and sets v0 to dst.
* It assumes that
* - src and dst don't overlap
* - src is readable
* - dst is writable
* memcpy uses the standard calling convention
*
* __copy_user copies up to len bytes from src to dst and sets a2 (len) to
* the number of uncopied bytes due to an exception caused by a read or write.
* __copy_user assumes that src and dst don't overlap, and that the call is
* implementing one of the following:
* copy_to_user
* - src is readable (no exceptions when reading src)
* copy_from_user
* - dst is writable (no exceptions when writing dst)
* __copy_user uses a non-standard calling convention; see
* include/asm-mips/uaccess.h
*
* When an exception happens on a load, the handler must
# ensure that all of the destination buffer is overwritten to prevent
* leaking information to user mode programs.
*/
/*
* Implementation
*/
/*
* The exception handler for loads requires that:
* 1- AT contain the address of the byte just past the end of the source
* of the copy,
* 2- src_entry <= src < AT, and
* 3- (dst - src) == (dst_entry - src_entry),
* The _entry suffix denotes values when __copy_user was called.
*
* (1) is set up up by uaccess.h and maintained by not writing AT in copy_user
* (2) is met by incrementing src by the number of bytes copied
* (3) is met by not doing loads between a pair of increments of dst and src
*
* The exception handlers for stores adjust len (if necessary) and return.
* These handlers do not need to overwrite any data.
*
* For __rmemcpy and memmove an exception is always a kernel bug, therefore
* they're not protected.
