From c9b01df34b445e5cc4f67d21e46280f537466969 Mon Sep 17 00:00:00 2001 From: Solomon Peachy Date: Mon, 27 Oct 2008 11:13:55 -0400 Subject: [PATCH] Staging: wlan-ng: Remove PCI/PLX/PCMCIA files. This portion of the driver is not needed at all, so remove it.

The lowest level functions are simply C-callable wrappers -* around the register accesses. The next higher level represents C-callable -* prism2 API functions that match the Intersil documentation as closely -* as is reasonable. The next higher layer implements common sequences -* of invokations of the API layer (e.g. write to bap, followed by cmd). -* -* Common sequences: -* hfa384x_drvr_xxx Highest level abstractions provided by the -* hfa384x code. They are driver defined wrappers -* for common sequences. These functions generally -* use the services of the lower levels. -* -* hfa384x_drvr_xxxconfig An example of the drvr level abstraction. These -* functions are wrappers for the RID get/set -* sequence. They call copy_[to|from]_bap() and -* cmd_access(). These functions operate on the -* RIDs and buffers without validation. The caller -* is responsible for that. -* -* API wrapper functions: -* hfa384x_cmd_xxx functions that provide access to the f/w commands. -* The function arguments correspond to each command -* argument, even command arguments that get packed -* into single registers. These functions _just_ -* issue the command by setting the cmd/parm regs -* & reading the status/resp regs. Additional -* activities required to fully use a command -* (read/write from/to bap, get/set int status etc.) -* are implemented separately. Think of these as -* C-callable prism2 commands. -* -* Lowest Layer Functions: -* hfa384x_docmd_xxx These functions implement the sequence required -* to issue any prism2 command. Primarily used by the -* hfa384x_cmd_xxx functions. -* -* hfa384x_bap_xxx BAP read/write access functions. -* Note: we usually use BAP0 for non-interrupt context -* and BAP1 for interrupt context. -* -* hfa384x_dl_xxx download related functions. -* -* Driver State Issues: -* Note that there are two pairs of functions that manage the -* 'initialized' and 'running' states of the hw/MAC combo. The four -* functions are create(), destroy(), start(), and stop(). create() -* sets up the data structures required to support the hfa384x_* -* functions and destroy() cleans them up. The start() function gets -* the actual hardware running and enables the interrupts. The stop() -* function shuts the hardware down. The sequence should be: -* create() -* . -* . Self contained test routines can run here, particularly -* . corereset() and test_hostif(). -* . -* start() -* . -* . Do interesting things w/ the hardware -* . -* stop() -* destroy() -* -* Note that destroy() can be called without calling stop() first. -* -------------------------------------------------------------------- -*/ - -/*================================================================*/ - -/* System Includes */ -#define WLAN_DBVAR prism2_debug -#include "version.h" - - -#include - -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include -#include - -#if (LINUX_VERSION_CODE < KERNEL_VERSION(2,5,0)) -#include -#else -#include -#endif - -#if (WLAN_HOSTIF == WLAN_PCMCIA) -#if (LINUX_VERSION_CODE < KERNEL_VERSION(2,6,13) ) -#include -#endif -#include -#include -#include -#include -#include -#endif - -#if ((WLAN_HOSTIF == WLAN_PLX) || (WLAN_HOSTIF == WLAN_PCI)) -#include -#include -#endif - -#include "wlan_compat.h" - -// XXXX #define CMD_IRQ - -/*================================================================*/ -/* Project Includes */ - -#include "p80211types.h" -#include "p80211hdr.h" -#include "p80211mgmt.h" -#include "p80211conv.h" -#include "p80211msg.h" -#include "p80211netdev.h" -#include "p80211req.h" -#include "p80211metadef.h" -#include "p80211metastruct.h" -#include "hfa384x.h" -#include "prism2mgmt.h" - -/*================================================================*/ -/* Local Constants */ - -static const UINT16 crc16tab[256] = -{ - 0x0000, 0xc0c1, 0xc181, 0x0140, 0xc301, 0x03c0, 0x0280, 0xc241, - 0xc601, 0x06c0, 0x0780, 0xc741, 0x0500, 0xc5c1, 0xc481, 0x0440, - 0xcc01, 0x0cc0, 0x0d80, 0xcd41, 0x0f00, 0xcfc1, 0xce81, 0x0e40, - 0x0a00, 0xcac1, 0xcb81, 0x0b40, 0xc901, 0x09c0, 0x0880, 0xc841, - 0xd801, 0x18c0, 0x1980, 0xd941, 0x1b00, 0xdbc1, 0xda81, 0x1a40, - 0x1e00, 0xdec1, 0xdf81, 0x1f40, 0xdd01, 0x1dc0, 0x1c80, 0xdc41, - 0x1400, 0xd4c1, 0xd581, 0x1540, 0xd701, 0x17c0, 0x1680, 0xd641, - 0xd201, 0x12c0, 0x1380, 0xd341, 0x1100, 0xd1c1, 0xd081, 0x1040, - 0xf001, 0x30c0, 0x3180, 0xf141, 0x3300, 0xf3c1, 0xf281, 0x3240, - 0x3600, 0xf6c1, 0xf781, 0x3740, 0xf501, 0x35c0, 0x3480, 0xf441, - 0x3c00, 0xfcc1, 0xfd81, 0x3d40, 0xff01, 0x3fc0, 0x3e80, 0xfe41, - 0xfa01, 0x3ac0, 0x3b80, 0xfb41, 0x3900, 0xf9c1, 0xf881, 0x3840, - 0x2800, 0xe8c1, 0xe981, 0x2940, 0xeb01, 0x2bc0, 0x2a80, 0xea41, - 0xee01, 0x2ec0, 0x2f80, 0xef41, 0x2d00, 0xedc1, 0xec81, 0x2c40, - 0xe401, 0x24c0, 0x2580, 0xe541, 0x2700, 0xe7c1, 0xe681, 0x2640, - 0x2200, 0xe2c1, 0xe381, 0x2340, 0xe101, 0x21c0, 0x2080, 0xe041, - 0xa001, 0x60c0, 0x6180, 0xa141, 0x6300, 0xa3c1, 0xa281, 0x6240, - 0x6600, 0xa6c1, 0xa781, 0x6740, 0xa501, 0x65c0, 0x6480, 0xa441, - 0x6c00, 0xacc1, 0xad81, 0x6d40, 0xaf01, 0x6fc0, 0x6e80, 0xae41, - 0xaa01, 0x6ac0, 0x6b80, 0xab41, 0x6900, 0xa9c1, 0xa881, 0x6840, - 0x7800, 0xb8c1, 0xb981, 0x7940, 0xbb01, 0x7bc0, 0x7a80, 0xba41, - 0xbe01, 0x7ec0, 0x7f80, 0xbf41, 0x7d00, 0xbdc1, 0xbc81, 0x7c40, - 0xb401, 0x74c0, 0x7580, 0xb541, 0x7700, 0xb7c1, 0xb681, 0x7640, - 0x7200, 0xb2c1, 0xb381, 0x7340, 0xb101, 0x71c0, 0x7080, 0xb041, - 0x5000, 0x90c1, 0x9181, 0x5140, 0x9301, 0x53c0, 0x5280, 0x9241, - 0x9601, 0x56c0, 0x5780, 0x9741, 0x5500, 0x95c1, 0x9481, 0x5440, - 0x9c01, 0x5cc0, 0x5d80, 0x9d41, 0x5f00, 0x9fc1, 0x9e81, 0x5e40, - 0x5a00, 0x9ac1, 0x9b81, 0x5b40, 0x9901, 0x59c0, 0x5880, 0x9841, - 0x8801, 0x48c0, 0x4980, 0x8941, 0x4b00, 0x8bc1, 0x8a81, 0x4a40, - 0x4e00, 0x8ec1, 0x8f81, 0x4f40, 0x8d01, 0x4dc0, 0x4c80, 0x8c41, - 0x4400, 0x84c1, 0x8581, 0x4540, 0x8701, 0x47c0, 0x4680, 0x8641, - 0x8201, 0x42c0, 0x4380, 0x8341, 0x4100, 0x81c1, 0x8081, 0x4040 -};
