| * tools: moveconfig: show suspicious boards with possible misconversionMasahiro Yamada2016-06-22-1/+31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are some cases where config options are moved, but they are ripped off at the final savedefconfig stage: - The moved option is not user-configurable, for example, due to a missing prompt in the Kconfig entry - The config was not defined in the original config header despite the Kconfig specifies it as non-bool type - The config define in the header contains reference to another macro, for example: #define CONFIG_CONS_INDEX (CONFIG_SYS_LPC32XX_UART - 2) The current moveconfig does not support recursive macro expansion. In these cases, the conversion is very likely to be an unexpected result. That is why I decided to display the log in yellow color in commit 5da4f857beac ("tools: moveconfig: report when CONFIGs are removed by savedefconfig"). It would be nice to display the list of suspicious boards when the tool finishes processing. It is highly recommended to check the defconfigs once again when this message is displayed.

| | | | | | | | | | | | | | | | | | | | | | | | | | Since commit 1d085568b3de ("tools: moveconfig: display log atomically in more readable format"), the function color_text() is clever enough to exclude LF from escape sequences.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The subprocess.Popen() does not change the child process's working directory if cwd=None is given. Let's exploit this fact to refactor the source directory handling. We no longer have to pass "-C <reference_src_dir>" to the sub-process because self.current_src_dir tracks the source tree against which we want to run defconfig/autoconf. The flag self.use_git_ref is not necessary either because we can know the current state by checking whether the self.current_src_dir is a valid string or None.

KSZ886x switches can be used in the following configuration modes: - Unmanaged mode with config stored in external EEPROM - Managed mode over SPI - Managed mode over I2C - Managed mode over mdio/mdc (aka MIIM or SMI) This patch supports only unmanaged and MIIM modes.

* | net: rtl8169: fix switching between adaptersStephen Warren2016-06-21-4/+9
|/ | | | | | | | | | | | | | | | | | | | | | | | The rtl8169 driver uses a global variable to store the register address of the adapter being operated upon. This is updated to point at the correct adapter when sending or receiving a packet, or shutting down the adapter, but not when initializing the adapter. Consequently, switching between different adapters within the same U-Boot runtime does not work correctly since the driver programs the wrong registers during rtl8169_eth_start() -> rtl8169_common_start() -> rtl8169_hw_start(). Note that since rtl8169_eth_stop() does set the global variable, the second consecutive attempt to use the "new" adapter did work even before this patch, because each time network usage is shut down, the network core calls stop, which sets the variable so that the next start does actually initialize the hardware, and the adapter works. Equally, rtl8169_eth_probe() calls rtl_init() which sets the global, so if using only a single device, or if picking the "right" device (based on probe order) when multiple devices are present, ioaddr will already be set correctly from the get-go, so the issue does not occur.

* Kconfig: Add a new DISTRO_DEFAULTS Kconfig optionHans de Goede2016-06-20-9/+23
| | | | | | | | | | | | | | | | | | | | | | DISTRO_DEFAULTS is intended to mirror / replace include/config_distro_defaults.h. The intend is for boards which include this file to select this from their Kconfig files and when moving setting to Kconfig which are #define-ed in config_distro_defaults.h to select this from DISTRO_DEFAULTS so that boards which have selected DISTRO_DEFAULTS will keep the same configuration as before without needing any defconfig file changes. The initial list of selected things matches all settings recently removed from config_distro_defaults.h because they have been converted to Kconfig, with the exception of CMD_ELF and CMD_NET, which have a default of y, if the default of these ever changes they should be selected by DISTRO_DEFAULTS too. For testing and example purposes this commit also converts ARCH_SUNXI to use DISTRO_DEFAULT instead of selecting everything it needs itself. Signed-off-by: Hans de Goede <hdegoede@redhat.com>

* ARM: allocate extra space for PSCI stack in secure section during link phaseChen-Yu Tsai2016-06-20-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | The PSCI implementation expects at most 2 pages worth of space reserved at the end of the secure section for its stacks. If PSCI is relocated to secure SRAM, then everything is fine. If no secure SRAM is available, and PSCI remains in main memory, the reserved memory space doesn't cover the space used by the stack. If one accesses PSCI after Linux has fully booted, the memory that should have been reserved for the PSCI stacks may have been used by the kernel or userspace, and would be corrupted. Observed after effects include the system hanging or telinit core dumping when trying to reboot. It seems the init process gets hit the most on my test bed. This fix allocates the space used by the PSCI stacks in the secure section by skipping pages in the linker script, but only when there is no secure SRAM, to avoid bloating the binary. This fix is only a stop gap. It would be better to rework the stack allocation mechanism, maybe with proper usage of CONFIG_ macros and an explicit symbol.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The sunxi SPL NAND controller driver supports use 'BootROM'-like configs, that is, configs where the ECC bytes and real data are interleaved in the page instead of putting ECC bytes in the OOB area. Doing that has several drawbacks: - since you're interleaving data and ECC bytes you can't use the whole page otherwise you might override the bad block marker with non-FF bytes. - to solve the bad block marker problem, the ROM code supports partially using the page, but this introduces a huge penalty both in term of read speed and NAND memory usage. While this is fine for rather small binaries(like the SPL one which is at maximum 24KB large), it becomes non-negligible for the bootloader image (several hundred of KB). - auto-detection of the page size is not reliable (this is in my opinion the biggest problem). If you get the page size wrong, you'll end up reading data at a different offset than what was specified by the caller and the reading may succeed (if valid data were written at this address). For all those reasons I think it's wiser to completely remove support for 'syndrome' configs. If we ever need to support it again, then I'd recommend specifying all the config parameters through Kconfig options.

| * | clk: convert API to match reset/mailbox styleStephen Warren2016-06-19-570/+985
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The following changes are made to the clock API: * The concept of "clocks" and "peripheral clocks" are unified; each clock provider now implements a single set of clocks. This provides a simpler conceptual interface to clients, and better aligns with device tree clock bindings. * Clocks are now identified with a single "struct clk", rather than requiring clients to store the clock provider device and clock identity values separately. For simple clock consumers, this isolates clients from internal details of the clock API. * clk.h is split so it only contains the client/consumer API, whereas clk-uclass.h contains the provider API. This aligns with the recently added reset and mailbox APIs. * clk_ops .of_xlate(), .request(), and .free() are added so providers can customize these operations if needed. This also aligns with the recently added reset and mailbox APIs. * clk_disable() is added. * All users of the current clock APIs are updated. * Sandbox clock tests are updated to exercise clock lookup via DT, and clock enable/disable. * rkclk_get_clk() is removed and replaced with standard APIs. Buildman shows no clock-related errors for any board for which buildman can download a toolchain. test/py passes for sandbox (which invokes the dm clk test amongst others).

| * | reset: implement a reset testStephen Warren2016-06-19-4/+251
| | | | | | | | | | | | | | | | | | | | | | | | | | | This adds a sandbox reset implementation (provider), a test client device, instantiates them both from Sandbox's DT, and adds a DM test that excercises everything.

| * | Add a reset driver framework/uclassStephen Warren2016-06-19-0/+446
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A reset controller is a hardware module that controls reset signals that affect other hardware modules or chips. This patch defines a standard API that connects reset clients (i.e. the drivers for devices affected by reset signals) to drivers for reset controllers/providers. Initially, DT is the only supported method for connecting the two. The DT binding specification (reset.txt) was taken from Linux kernel v4.5's Documentation/devicetree/bindings/reset/reset.txt.
