157 * I know that polling/delaying is frowned upon. However, this procedure
158 * with polling is needed while downloading the firmware. At this stage,
159 * the hardware does unfortunately not create any interrupts.
161 * Fortunately, this function is never used once the firmware is in
164 * As a reference, see the "Firmware Specification v5.1", page 18
165 * and 19. I did not follow their suggested timing to the word,
166 * but this works nice & fast anyway.

172 for (i = 0; i < 100000; i++) {

184 * First the bitmasks for the host/card interrupt/status registers:
186 #define IF_CS_BIT_TX 0x0001
187 #define IF_CS_BIT_RX 0x0002
188 #define IF_CS_BIT_COMMAND 0x0004
189 #define IF_CS_BIT_RESP 0x0008
190 #define IF_CS_BIT_EVENT 0x0010
191 #define IF_CS_BIT_MASK 0x001f
196 * It's not really clear to me what the host status register is for. It
197 * needs to be set almost in union with "host int cause". The following
198 * bits from above are used:
200 * IF_CS_BIT_TX driver downloaded a data packet
201 * IF_CS_BIT_RX driver got a data packet
202 * IF_CS_BIT_COMMAND driver downloaded a command
203 * IF_CS_BIT_RESP not used (has some meaning with powerdown)
204 * IF_CS_BIT_EVENT driver read a host event
206 #define IF_CS_HOST_STATUS 0x00000000
209 * With the host int cause register can the host (that is, Linux) cause
210 * an interrupt in the firmware, to tell the firmware about those events:
212 * IF_CS_BIT_TX a data packet has been downloaded
213 * IF_CS_BIT_RX a received data packet has retrieved
214 * IF_CS_BIT_COMMAND a firmware block or a command has been downloaded
215 * IF_CS_BIT_RESP not used (has some meaning with powerdown)
216 * IF_CS_BIT_EVENT a host event (link lost etc) has been retrieved
218 #define IF_CS_HOST_INT_CAUSE 0x00000002
221 * The host int mask register is used to enable/disable interrupt. However,
222 * I have the suspicion that disabled interrupts are lost.
224 #define IF_CS_HOST_INT_MASK 0x00000004
227 * Used to send or receive data packets:
229 #define IF_CS_WRITE 0x00000016
230 #define IF_CS_WRITE_LEN 0x00000014
231 #define IF_CS_READ 0x00000010
232 #define IF_CS_READ_LEN 0x00000024
235 * Used to send commands (and to send firmware block) and to
236 * receive command responses:
238 #define IF_CS_CMD 0x0000001A
239 #define IF_CS_CMD_LEN 0x00000018
240 #define IF_CS_RESP 0x00000012
241 #define IF_CS_RESP_LEN 0x00000030
244 * The card status registers shows what the card/firmware actually
247 * IF_CS_BIT_TX you may send a data packet
248 * IF_CS_BIT_RX you may retrieve a data packet
249 * IF_CS_BIT_COMMAND you may send a command
250 * IF_CS_BIT_RESP you may retrieve a command response
251 * IF_CS_BIT_EVENT the card has a event for use (link lost, snr low etc)
253 * When reading this register several times, you will get back the same
254 * results --- with one exception: the IF_CS_BIT_EVENT clear itself
257 * Not that we don't rely on BIT_RX,_BIT_RESP or BIT_EVENT because
258 * we handle this via the card int cause register.
260 #define IF_CS_CARD_STATUS 0x00000020
261 #define IF_CS_CARD_STATUS_MASK 0x7f00
264 * The card int cause register is used by the card/firmware to notify us
265 * about the following events:
267 * IF_CS_BIT_TX a data packet has successfully been sentx
268 * IF_CS_BIT_RX a data packet has been received and can be retrieved
269 * IF_CS_BIT_COMMAND not used
270 * IF_CS_BIT_RESP the firmware has a command response for us
271 * IF_CS_BIT_EVENT the card has a event for use (link lost, snr low etc)
273 #define IF_CS_CARD_INT_CAUSE 0x00000022
276 * This is used to for handshaking with the card's bootloader/helper image
277 * to synchronize downloading of firmware blocks.
279 #define IF_CS_SQ_READ_LOW 0x00000028
280 #define IF_CS_SQ_HELPER_OK 0x10
283 * The scratch register tells us ...
285 * IF_CS_SCRATCH_BOOT_OK the bootloader runs
286 * IF_CS_SCRATCH_HELPER_OK the helper firmware already runs
288 #define IF_CS_SCRATCH 0x0000003F
289 #define IF_CS_SCRATCH_BOOT_OK 0x00
290 #define IF_CS_SCRATCH_HELPER_OK 0x5a
293 * Used to detect ancient chips:
295 #define IF_CS_PRODUCT_ID 0x0000001C
296 #define IF_CS_CF8385_B1_REV 0x12
297 #define IF_CS_CF8381_B3_REV 0x04
298 #define IF_CS_CF8305_B1_REV 0x03
301 * Used to detect other cards than CF8385 since their revisions of silicon
302 * doesn't match those from CF8385, eg. CF8381 B3 works with this driver.
