* | usb: dwc2-otg: make regs_phy (in platdata) a uintptr_tPhilipp Tomsich2018-12-061-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The regs_phy field of the platform data structure for dwc2-otg is today declared an unsigned int, but will eventually be cast into a void* for a writel operation. This triggers errors on modern GCC versions. E.g. we get the following error with GCC 6.3: drivers/usb/phy/rockchip_usb2_phy.c: In function 'property_enable': arch/arm/include/asm/io.h:49:29: error: cast to pointer from integer of different size [-Werror=int-to-pointer-cast] #define __arch_putl(v,a) (*(volatile unsigned int *)(a) = (v)) ^ arch/arm/include/asm/io.h:117:48: note: in expansion of macro '__arch_putl' #define writel(v,c) ({ u32 __v = v; __iowmb(); __arch_putl(__v,c); __v; }) ^~~~~~~~~~~ drivers/usb/phy/rockchip_usb2_phy.c:61:2: note: in expansion of macro 'writel' writel(val, pdata->regs_phy + reg->offset); ^~~~~~ This commit changes regs_phy to be a uintptr_t to ensure that it is large enough to hold any valid pointer (and fix the associated warning).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Even if U-Boot does not use this, some libraries do. Add back this header file so that the build does not fall back to using the host version, which may include stdint.h and break the build due to conflicts with uint64_t, etc. This partially reverts commit dee37fc99d94 ("Remove <inttypes.h> includes and PRI* usages in printf() entirely") The only change from the file that was in U-Boot until recently is that it now comes twice as close to passing checkpatch.

| * | time: Update mdelay() to delay in one large chunkSimon Glass2018-12-051-2/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current function delays in one millisecond at a time. This does not work well on sandbox since it results in lots of calls to usleep(1000) in a tight loop. This makes the sleep duration quite variable since each call results in a sleep of *at least* 1000us, but possibly more. Depending on how busy the machine is, the sleep time can change quite a bit. We cannot fix this in general, but we can reduce the effect by doing a single sleep. The multiplication works fine with an unsigned long argument up until a sleep time of about 4m milliseconds. This is over an hour and we can be sure that delays of that length are not useful. Update the mdelay() function to call udelay() only once with the calculated delay value.

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).

This change implies that the FDT and initrd will always be copied into the first 256 MiB of RAM instead of being used in place, which can cause various kinds of inobvious problems. The simpler problems include FDT or initrd being overwritten or being used from unaligned addresses, especially on ARM64. The overhead of copying the FDT to aligned location is negligible and these problems go away, so the benefit is significant. Regarding alignment problems with fitImage. The alignment of DT properties is always 32 bits, which implies that the alignment of the "data" property in fitImage is also 32 bits. The /incbin/ syntax plays no role here. The kernel expects all elements, including DT and initrd, to be aligned to 64 bits on ARM64, thus using them in place may not be possible. Using the bootm_size assures correct alignment, again with negligible overhead.

Maybe the memory maps are incomplete, maybe it's used as workaround for broken DMA. But whatever the reason may be, a platform can say that it does not wish to have its RAM accessed above a certain address by defining board_get_usable_ram_top(). In the efi_loader world, we ignored that hint, mostly because very few boards actually have real restrictions around this. So let's honor the board's wish to not access high addresses during boot time. The best way to do so is by indicating the respective pages as "allocated by firmware". That way, Operating Systems will still use the pages after boot, but before boot no allocation will use them.

On most ARMv8 system the actual reset relies on PSCI. Depending on whether the PSCI firmware resides the hypervisor (EL2) or in the secure monitor (EL3) either an HVC or an SMC command has to be issued. The current implementation always uses SMC. This results in crashes on systems where the PSCI firmware is implemented in the hypervisor, e.g. qemu-arm64_defconfig. The logic to decide which call is needed based on the device tree is already implemented in the PSCI firmware driver. During the EFI runtime the device driver model is not available. But we can minimize code duplication by merging the EFI runtime reset and poweroff code with the PSCI firmware driver. As the same HVC/SMC problem is also evident for the ARMv8 do_poweroff and reset_misc routines let's move them into the same code module.
