Linux-2.6.12-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!

+ Say Y here if you want to attach PCMCIA- or PC-cards to your Linux
+ computer. 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.
+

+ Say Y here to enable PCMCIA subsystem debugging. You
+ will need to choose the debugging level either via the
+ kernel command line, or module options depending whether
+ you build the PCMCIA as modules.
+
+ The kernel command line options are:
+ pcmcia_core.pc_debug=N
+ ds.pc_debug=N
+ sa11xx_core.pc_debug=N
+
+ The module option is called pc_debug=N
+

+ This option enables support for 16-bit PCMCIA cards. Most older
+ PC-cards are such 16-bit PCMCIA cards, so unless you know you're
+ only using 32-bit CardBus cards, say Y or M here.
+
+ To use 16-bit PCMCIA 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>.

+ ---help---
+ CardBus is a bus mastering architecture for PC-cards, which allows
+ for 32 bit PC-cards (the original PCMCIA standard specifies only
+ a 16 bit wide bus). Many newer PC-cards are actually CardBus cards.
+
+ To use 32 bit PC-cards, you also need a CardBus compatible host
+ bridge. Virtually all modern PCMCIA bridges do this, and most of
+ them are "yenta-compatible", so say Y or M there, too.

+ *
+ * Device driver for the PCMCIA controller module of the
+ * Hitachi HD64465 handheld companion chip.
+ *
+ * Note that the HD64465 provides a very thin PCMCIA host bridge
+ * layer, requiring a lot of the work of supporting cards to be
+ * performed by the processor. For example: mapping of card
+ * interrupts to processor IRQs is done by IRQ demuxing software;
+ * IO and memory mappings are fixed; setting voltages according
+ * to card Voltage Select pins etc is done in software.
+ *
+ * Note also that this driver uses only the simple, fixed,
+ * 16MB, 16-bit wide mappings to PCMCIA spaces defined by the
+ * HD64465. Larger mappings, smaller mappings, or mappings of
+ * different width to the same socket, are all possible only by
+ * involving the SH7750's MMU, which is considered unnecessary here.
+ * The downside is that it may be possible for some drivers to
+ * break because they need or expect 8-bit mappings.
+ *
+ * This driver currently supports only the following configuration:
+ * SH7750 CPU, HD64465, TPS2206 voltage control chip.

+ * as described below.
+ *
+ * If the defaults aren't correct, you may override them with a pcmv
+ * setup argument: pcmv=<pcm vcc>,<pcm vpp>,<cf vcc>. The units are
