mtd: bcm47xxsflash: use ioremap_cache() instead of KSEG0ADDR() 2016-04-04T07:07:57+00:00 Brian Norris computersforpeace@gmail.com 2016-02-26T10:50:28+00:00 5651d6aaf489d1db48c253cf884b40214e91c2c5 Using KSEG0ADDR makes code highly MIPS dependent and not portable. Thanks to the fix a68f376 ("MIPS: io.h: Define `ioremap_cache'") we can use ioremap_cache which is generic and supported on MIPS as well now. KSEG0ADDR was translating 0x1c000000 into 0x9c000000. With ioremap_cache we use MIPS's __ioremap (and then remap_area_pages). This results in different address (e.g. 0xc0080000) but it still should be cached as expected and it was successfully tested with BCM47186B0. Other than that drivers/bcma/driver_chipcommon_sflash.c nicely setups a struct resource for access window, but we wren't using it. Use it now and drop duplicated info.

As next task we will want to move flash code to ChipCommon driver as: 1) Flash controllers are accesible using ChipCommon registers 2) This code isn't MIPS specific This change prepares bcma for that.

mtd: bcm47xxnflash: really unregister NAND on device removal 2015-12-14T18:11:09+00:00 Brian Norris computersforpeace@gmail.com 2015-12-09T01:04:59+00:00 665d2c2848f14c0c2a2e89192bde9073c4d352f7 The field bcma_nflash::mtd is never set to be non-zero anywhere, but we test for it in the removal path. So the MTD is never unregistered. Also, we should use nand_release(), not mtd_device_unregister(). Finally, we don't need to use the 'platdata' for stashing/retrieving our *driver* data -- that's what *_{get,set}_drvdata() are for. So, kill off bcm_nflash::mtd, and stash the struct bcm47xxnflash in drvdata instead. Also move the forward declaration of mtd_info up a bit, since struct bcma_sflash should be using it.
