+ * These macros are intended for use when there is a need to copy a low-level
+ * function body into special memory.
+ *
+ * For example, when reconfiguring the SDRAM controller, the code doing the
+ * reconfiguration may need to run from SRAM.
+ *
+ * NOTE: that the copied function body must be entirely self-contained and
+ * position-independent in order for this to work properly.
+ *
+ * NOTE: in order for embedded literals and data to get referenced correctly,
+ * the alignment of functions must be preserved when copying.  To ensure this,
+ * the source and destination addresses for fncpy() must be aligned to a
+ * multiple of 8 bytes: you will be get a BUG() if this condition is not met.
+ * You will typically need a ".align 3" directive in the assembler where the
+ * function to be copied is defined, and ensure that your allocator for the
+ * destination buffer returns 8-byte-aligned pointers.
+ *
+ * Typical usage example:
+ *
+ * extern int f(args);
+ * extern uint32_t size_of_f;
+ * int (*copied_f)(args);
+ * void *sram_buffer;
+ *
+ * copied_f = fncpy(sram_buffer, &f, size_of_f);
+ *
+ * ... later, call the function: ...
+ *
+ * copied_f(args);
+ *
+ * The size of the function to be copied can't be determined from C:
+ * this must be determined by other means, such as adding assmbler directives
+ * in the file where f is defined.

-
-   This file was cloned from the 7952x implementation.  It would be
-   better to share them, but we're taking an easier approach for the
-   time being.

-   -----------
-   DESCRIPTION
-   -----------
-
-   Only one panel may be defined at a time.
-
-   The pixel clock is calculated to be no greater than the target.
-
-   Each timing value is accompanied by a specification comment.
-
-     UNITS/MIN/TYP/MAX
-
-   Most of the units will be in clocks.
-
-   USE_RGB555
-
-     Define this macro to configure the AMBA LCD controller to use an
-     RGB555 encoding for the pels instead of the normal RGB565.
-
-   LPD9520, LPD79524, LPD7A400, LPD7A404-10, LPD7A404-11
-
-     These boards are best approximated by 555 for all panels.  Some
-     can use an extra low-order bit of blue in bit 16 of the color
-     value, but we don't have a way to communicate this non-linear
-     mapping to the kernel.

-/* NOTES
-   -----
-
-   o *** This driver is cribbed from the 7952x implementation.
-	 Some comments may not apply.
-
-   o This driver contains sufficient logic to control either the
-     serial EEPROMs or the audio codec.  It is included in the kernel
-     to support the codec.  The EEPROMs are really the responsibility
-     of the boot loader and should probably be left alone.
-
-   o The code must be augmented to cope with multiple, simultaneous
-     clients.
-     o The audio codec writes to the codec chip whenever playback
-       starts.
-     o The touchscreen driver writes to the ads chip every time it
-       samples.
-     o The audio codec must write 16 bits, but the touch chip writes
-       are 8 bits long.
-     o We need to be able to keep these configurations separate while
-       simultaneously active.
