2018-12-06pinctrl: stm32: make pinctrl use hwspinlockBenjamin Gaignard
Protect configuration registers with a hardware spinlock. If a hwspinlock is defined in the device-tree node used it to be sure that none of the others processors on the SoC could change the configuration at the same time.

2018-12-06clk: Allow clock defaults to be set during re-reloc state for SPL onlyPhilipp Tomsich
In commit e5e06b65ad65 ("clk: Allow clock defaults to be set also during re-reloc state") the earlier guard against setting clock defaults in pre-reloc state was removed. While it is easy to filter 'assigned-clocks' properties for SPL using CONFIG_OF_SPL_REMOVE_PROPS, no such mechanism exists for the pre-reloc stage of the full U-Boot. With the default defconfig for the RK3399-Q7 (which filter the 'assigned-clocks' property for the DTS used by SPL anyway), this caused a pause during startup of the full U-Boot stage that lasted for almost 10s (due to the CPU not having been clocked up yet). This reintroduces the guard from commit f4fcba5c5baa ("clk: Allow clock defaults to be set also during re-reloc state") and extends it to only apply outside of a TPL/SPL build: i.e. clk_set_defaults will now run in pre-reloc state for SPL, but only after reloc for the full U-Boot.

2018-12-06w1: fix occasional enumeration failureMartin Fuzzey
Sometimes enumeration fails (about 1 in 50 times on my custom board). The underlying reason is probably electrical but Linux does not have the problem. Comparing the Linux / u-boot implementations shows that Linux retries the error case whereas u-boot aborts early. Removing the early abort in u-boot fixes the problem.

2018-12-06mtd: sf: Make sf_mtd.c more robustBoris Brezillon
SPI flash based MTD devs can be registered/unregistered at any time through the sf probe command or the spi_flash_free() function. This commit does not try to fix the root cause as it would probably require rewriting most of the code and have an mtd_info object instance per spi_flash object (not to mention that the the spi-flash layer is likely to be replaced by a spi-nor layer ported from Linux). Instead, we try to be as safe as can be by checking the code returned by del_mtd_device() and complain loudly when there's nothing we can do about the deregistration failure. When that happens we also reset sf_mtd_info.priv to NULL, and check for NULL pointer in the mtd hooks so that -ENODEV is returned instead of hitting a NULL pointer dereference exception when the MTD instance is later accessed by a user.

2018-12-06mtd: sf: Unregister the MTD device prior to removing the spi_flash objBoris Brezillon
The DM implementation of spi_flash_free() does not unregister the MTD device before removing the spi dev object. This leads to a use-after-free bug when the MTD device is later accessed by a MTD user (observed when attaching the device to UBI after env_sf_load() has called spi_flash_free()). Implement ->remove() and call spi_flash_mtd_unregister() from there.

2018-12-06mtd: Don't stop MTD partition creation when it fails on one deviceBoris Brezillon
MTD partition creation code is a bit tricky. It tries to figure out when things have changed (either MTD dev list or mtdparts/mtdids vars) and when that happens it first deletes all the partitions that had been previously created and then creates the new ones based on the new mtdparts/mtdids values. But before deleting the old partitions, it ensures that none of the currently registered parts are being used and bails out when that's not the case. So, we end up in a situation where, if at least one MTD dev has one of its partitions used by someone (UBI for instance), the partitions update logic no longer works for other devs. Rework the code to relax the logic and allow updates of MTD parts on devices that are not being used (we still refuse to updates parts on devices who have at least one of their partitions used by someone).

2018-12-04mmc: Do not issue CMD 6 on SD 1.00 and SD 1.01Marek Vasut
According to SD Specifications Part 1 Physical Layer Simplified Specification Version 6.00 August 29, 2018, section 4.3.10 (Switch Function Command) and section 5.6 (SCR register), SD cards version 1.00 and 1.01 do not support the SD CMD 6. Currently, U-Boot will issue CMD 6 unconditionally in sd_set_card_speed() while configuring the bus for selected frequency. This will make SD cards version 1.00 and 1.01 time out and thus fail detection altogether. Fix this by not sending CMD 6 on such cards. Tested on Matsushita Electric Industrial Co., Ltd.
