[ARM PATCH] 1828/2: rework SA11xx PCMCIA code structure for better sharing of generic 

 code

Patch from Nicolas Pitre

[Updated after comments on patch #1828/1]

This patch moves things around and rename a few files/functions/structures
to be shared with PXA2xx PCMCIA support (coming in a separate patch) and
maybe others SOCs. No functional change were made so SA11xx users
shouldn't see any difference.

* a minimum value of 165ns, as well. Section 4.7.2 (describing
* common and attribute memory write timing) says that twWE has a
* minimum value of 150ns for a 250ns cycle time (for 5V operation;
* see section 4.7.4), or 300ns for a 600ns cycle time (for 3.3V

* operation), or 300ns for a 600ns cycle time (for 3.3V operation).
*
* When configuring memory maps, Card Services appears to adopt the policy
* that a memory access time of "0" means "use the default." The default
* PCMCIA I/O command width time is 165ns. The default PCMCIA 5V attribute
* and memory command width time is 150ns; the PCMCIA 3.3V attribute and

* The PC Card Standard, Release 7, section 4.13.4, says that twIORD

* a minimum value of 165ns, as well. Section 4.7.2 (describing
* common and attribute memory write timing) says that twWE has a
* minimum value of 150ns for a 250ns cycle time (for 5V operation;
* see section 4.7.4), or 300ns for a 600ns cycle time (for 3.3V
* operation, also section 4.7.4). Section 4.7.3 says that taOE
* has a maximum value of 150ns for a 300ns cycle time (for 5V
* operation), or 300ns for a 600ns cycle time (for 3.3V operation).
*
* When configuring memory maps, Card Services appears to adopt the policy
* that a memory access time of "0" means "use the default." The default
* PCMCIA I/O command width time is 165ns. The default PCMCIA 5V attribute
* and memory command width time is 150ns; the PCMCIA 3.3V attribute and
* memory command width time is 300ns.
