2021-07-06sandbox: cros-ec: Add tests for the Chromium OS EC PWM driverAlper Nebi Yasak
This patch adds a limited pulse-width modulator to sandbox's Chromium OS Embedded Controller emulation. The emulated PWM device supports multiple channels but can only set a duty cycle for each, as the actual EC doesn't expose any functionality or information other than that. Though the EC supports specifying the PWM channel by its type (e.g. display backlight, keyboard backlight), this is not implemented in the emulation as nothing in U-Boot uses this type specification. This emulated PWM device is then used to test the Chromium OS PWM driver in sandbox. Adding the required device node to the sandbox test device-tree unfortunately makes it the first PWM device, so this also touches some other tests to make sure they still use the sandbox PWM.

2021-07-06sandbox: fix sandbox_reset()Heinrich Schuchardt
state_uninit() and dm_uninit() are mutually exclusive: state_uninit() prints via drivers. So it cannot be executed after dm_uninit(). dm_uninit() requires memory. So it cannot be executed after state_uninit() which releases all memory. Just skip dm_uninit() when resetting the sandbox. We will wake up in a new process and allocate new memory. So this cleanup is not required. We don't do it in sandbox_exit() either. This avoids a segmentation error when efi_reset_system_boottime() is invoked by a UEFI application.

2021-07-06sandbox: ensure that state->ram_buf is in low memoryHeinrich Schuchardt
Addresses in state->ram_buf must be in the low 4 GiB of the address space. Otherwise we cannot correctly fill SMBIOS tables. This shows up in warnings like: WARNING: SMBIOS table_address overflow 7f752735e020 Ensure that state->ram_buf is initialized by the first invocation of os_malloc().

2021-07-06sandbox: Support signal handling only when requestedSimon Glass
At present if sandbox crashes it prints a message and tries to exit. But with the recently introduced signal handler, it often seems to get stuck in a loop until the stack overflows: Segmentation violation Segmentation violation Segmentation violation Segmentation violation Segmentation violation Segmentation violation Segmentation violation ... The signal handler is only useful for a few tests, as I understand it. Make it optional. Signed-off-by: Simon Glass <sjg@chromium.org>

2021-06-28arm64: Fix relocation of env_addr if POSITION_INDEPENDENT=yKunihiko Hayashi
If both POSITION_INDEPENDENT and SYS_RELOC_GD_ENV_ADDR are enabled, wherever original env is placed anywhere, it should be relocated to the right address. Relocation offset gd->reloc_off is calculated with SYS_TEXT_BASE in setup_reloc() and env address gd->env_addr is relocated by the offset in initr_reloc_global_data(). gd->env_addr = (orig env) + gd->reloc_off = (orig env) + (gd->relocaddr - SYS_TEXT_BASE) However, SYS_TEXT_BASE isn't always runtime base address when POSITION_INDEPENDENT is enabled. So the relocated env_addr might point to wrong address. For example, if SYS_TEXT_BASE is zero, gd->env_addr is out of memory location and memory exception will occur. There is a difference between linked address such as SYS_TEXT_BASE and runtime base address. In _main, the difference is calculated as "run-vs-link" offset. The env_addr should also be added to the offset to fix the address. gd->env_addr = (orig env) + ("run-vs-link" offset) + gd->reloc_off = (orig env) + (SYS_TEXT_BASE - _start) + (gd->relocaddr - SYS_TEXT_BASE) = (orig env) + (gd->relocaddr - _start) Cc: Marek Vasut <marex@denx.de> Signed-off-by: Kunihiko Hayashi <hayashi.kunihiko@socionext.com> Acked-by: Marek Vasut <marex@denx.de> Tested-by: Marek Vasut <marex@denx.de>

2021-06-23global_data: Ensure we have <config.h> when symbols are not in Kconfig yetTom Rini
All symbols that are defined in Kconfig will always be defined (or not) prior to preprocessing due to the -include directive while building. However, symbols which are not yet migrated will only be defined (or not) once the board config.h is included, via <config.h>. While the end goal must be to migrate all symbols, today we have cases where the size of gd will get mismatched within the build, based on include order. Mitigate this by making sure that any <asm/global_data.h> that uses symbols not in Kconfig does start with <config.h>. Remove this when not needed.

2021-06-23x86: Discard .note.gnu.property sectionsBin Meng
When switching to kernel.org x86_64 gcc 11.1.0 toolchain, u-boot.rom built from qemu-x86_defconfig no longer boots anymore. Investigation shows that U-Boot fails at a very early stage during the boot process, in fdtdec_prepare_fdt() where fdt_check_header() complains that there is not a valid device tree found at gd->fdt_blob which points to _end. Now _end points to an allocated section .note.gnu.property which of course is wrong. This issue is however not seen when using the default Ubuntu 20.04 gnu toolchain (gcc 9.3.0 with binutils 2.34). Further investigation shows that it is caused by a behavior change of binutils v2.36 which is part of the kernel.org gcc 11.1.0 toolchain, via the following commit: 939b95c77bf2 ("Linux/x86: Configure gas with --enable-x86-used-note by default") In fact, there was already a regression bug report [1] for binutils two months ago, but the binutils folks did not think it is a bug :( To resolve this, there are several options: * pass -Wa,-mx86-used-note=no to gas * pass -R .note.gnu.property to objcopy * discard the section in the linker script Linux kernel uses the discard way [2], so let's do the same for U-Boot.

2021-06-23arm64: zynqmp: Remove gpio from aliases listMichal Simek
It is not recommended to have aliases for gpio. In past it was used in Linux for assigning numbers via sysfs which is deprecated and libgpiod should be used instead. In U-Boot this number is used for seq number but gpio offset are not counted from this number. That's why having these aliases only for seq number is not needed. As is done in Linux it is the best to use full gpio name instead of sequence number which depends on sequence in binding. Signed-off-by: Michal Simek <michal.simek@xilinx.com>
