+What:	i386/x86_64 bzImage symlinks
+When:	April 2008
+
+Why:	The i386/x86_64 merge provides a symlink to the old bzImage
+	location so not yet updated user space tools, e.g. package
+	scripts, do not break.

+ *	15 Sept 2005 Eric Biederman: 64bit PIC support
+ *
+ *	Entry: CS:IP point to the start of our code, we are

+ *	trampoline page to make our stack and everything else

+ *	On entry to trampoline_data, the processor is in real mode
+ *	with 16-bit addressing and 16-bit data.  CS has some value
+ *	and IP is zero.  Thus, data addresses need to be absolute
+ *	(no relocation) and are taken with regard to r_base.
+ *
+ *	With the addition of trampoline_level4_pgt this code can
+ *	now enter a 64bit kernel that lives at arbitrary 64bit
+ *	physical addresses.

- *	Trampoline.S	Derived from Setup.S by Linus Torvalds
- *
- *	4 Jan 1997 Michael Chastain: changed to gnu as.
- *	15 Sept 2005 Eric Biederman: 64bit PIC support
- *
- *	Entry: CS:IP point to the start of our code, we are 
- *	in real mode with no stack, but the rest of the 
- *	trampoline page to make our stack and everything else
- *	is a mystery.
- *
- *	In fact we don't actually need a stack so we don't
- *	set one up.
- *
- *	On entry to trampoline_data, the processor is in real mode
- *	with 16-bit addressing and 16-bit data.  CS has some value
- *	and IP is zero.  Thus, data addresses need to be absolute
- *	(no relocation) and are taken with regard to r_base.
- *
- *	With the addition of trampoline_level4_pgt this code can
- *	now enter a 64bit kernel that lives at arbitrary 64bit
- *	physical addresses.
- *
- *	If you work on this file, check the object module with objdump
- *	--full-contents --reloc to make sure there are no relocation
- *	entries.

+ * context as SDIO access functions must be able to sleep.
+ *
+ * Because we need to lock the SDIO host to ensure an exclusive access to

+/* NOTES:
+ *
+ * - For now, we won't try to interoperate with a real mmc/sd/sdio
+ *   controller, although some of them do have hardware support for
+ *   SPI protocol.  The main reason for such configs would be mmc-ish
+ *   cards like DataFlash, which don't support that "native" protocol.
+ *
+ *   We don't have a "DataFlash/MMC/SD/SDIO card slot" abstraction to
+ *   switch between driver stacks, and in any case if "native" mode
+ *   is available, it will be faster and hence preferable.
+ *
+ * - MMC depends on a different chipselect management policy than the
+ *   SPI interface currently supports for shared bus segments:  it needs
+ *   to issue multiple spi_message requests with the chipselect active,
+ *   using the results of one message to decide the next one to issue.
+ *
+ *   Pending updates to the programming interface, this driver expects
+ *   that it not share the bus with other drivers (precluding conflicts).
+ *
+ * - We tell the controller to keep the chipselect active from the
+ *   beginning of an mmc_host_ops.request until the end.  So beware
+ *   of SPI controller drivers that mis-handle the cs_change flag!
+ *
+ *   However, many cards seem OK with chipselect flapping up/down
+ *   during that time ... at least on unshared bus segments.

+ * This is a conceptually ridiculous driver, but it is required by the way
+ * the Ricoh multi-function R5C832 works. This chip implements firewire
+ * and four different memory card controllers. Two of those controllers are
+ * an SDHCI controller and a proprietary MMC controller. The linux SDHCI
+ * driver supports MMC cards but the chip detects MMC cards in hardware
+ * and directs them to the MMC controller - so the SDHCI driver never sees
+ * them. To get around this, we must disable the useless MMC controller.
+ * At that point, the SDHCI controller will start seeing them. As a bonus,
+ * a detection event occurs immediately, even if the MMC card is already
+ * in the reader.
+ *
+ * The relevant registers live on the firewire function, so this is unavoidably
+ * ugly. Such is life.
