- * 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.
