thunderbolt: Split NVM read/write generic functions out from usb4.c 2021-05-31T11:37:48+00:00 Mika Westerberg mika.westerberg@linux.intel.com 2021-04-01T13:54:15+00:00 9b383037770fcd6b03dd3793c89055b8490957e0 We do this for Thunderbolt 2/3 devices through DMA port, USB4 devices and retimers pretty much the same way. Only the actual block read/write is different. For this reason split out the NVM read/write functions from usb4.c to nvm.c and make USB4 device code call these when needed.

thunderbolt: Add support for separating the flush to SPI and authenticate 2020-07-01T10:51:49+00:00 Mario Limonciello mario.limonciello@dell.com 2020-06-23T16:14:28+00:00 4b794f8066e84818c172c81024f1d61071f14710 This allows userspace to have a shorter period of time that the device is unusable and to call it at a more convenient time. For example flushing the image may happen while the user is using the machine and authenticating/rebooting may happen while logging out.

thunderbolt: Split common NVM functionality into a separate file 2020-06-22T16:58:32+00:00 Mika Westerberg mika.westerberg@linux.intel.com 2020-03-05T09:37:15+00:00 719a5fe87ecd71d140c3ef76d855c70f82893411 We are going to reuse some of this functionality to implement retimer NVM upgrade so move common NVM functionality into its own file. We also rename the structure from tb_switch_nvm to tb_nvm to make it clear that it is not just for switches. Signed-off-by: Mika Westerberg <mika.westerberg@linux.intel.com>
