* | Kconfig: Move CONFIG_FIT and related options to KconfigSimon Glass2016-03-14-1/+1
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are already two FIT options in Kconfig but the CONFIG options are still in the header files. We need to do a proper move to fix this. Move these options to Kconfig and tidy up board configuration: CONFIG_FIT CONFIG_OF_BOARD_SETUP CONFIG_OF_SYSTEM_SETUP CONFIG_FIT_SIGNATURE CONFIG_FIT_BEST_MATCH CONFIG_FIT_VERBOSE CONFIG_OF_STDOUT_VIA_ALIAS CONFIG_RSA Unfortunately the first one is a little complicated. We need to make sure this option is not enabled in SPL by this change. Also this option is enabled automatically in the host builds by defining CONFIG_FIT in the image.h file. To solve this, add a new IMAGE_USE_FIT #define which can be used in files that are built on the host but must also build for U-Boot and SPL. Note: Masahiro's moveconfig.py script is amazing.

* | allow LED initialization without STATUS_LED_BOOTBernhard Nortmann2015-10-24-2/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For current U-Boot to initialize status LEDs via status_led_init(), it is required to have both CONFIG_STATUS_LED and STATUS_LED_BOOT defined. This may be a particular concern with GPIO LEDs, where __led_init() is required to correctly set up the GPIO (gpio_request and gpio_direction_output). Without STATUS_LED_BOOT the initialization isn't called, which could leave the user with a non-functional "led" command - due to the fact that the LED routines in gpio_led.c use gpio_set_value() just fine, but the GPIO never got set up properly in the first place. I think having CONFIG_STATUS_LED is sufficient to justify a corresponding call to status_led_init(), even with no STATUS_LED_BOOT defined. To do so, common/board_r.c needs call that routine, so it now is exposed via status_led.h.

* | add generic stubs for GPIO LEDsBernhard Nortmann2015-10-23-0/+54
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For boards that support LEDs driven via GPIO (CONFIG_GPIO_LED), it may be useful to have some generic stubs (wrapper functions) for the "colored" LEDs. This allows defining STATUS_LED_* values directly to GPIO numbers, e.g.: #define STATUS_LED_GREEN 248 /* = PH24 */ To keep those optional, it's probably best to introduce an additional configuration setting. I've chosen CONFIG_GPIO_LED_STUBS for that. Placing the code in drivers/misc/gpio_led.c also ensures that it automatically depends on CONFIG_GPIO_LED too.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is a hole in shadow registers address map of size 0x100 between bank 5 and bank 6 on iMX6QP, iMX6DQ, iMX6SDL, iMX6SX and iMX6UL. Bank 5 ends at 0x6F0 and Bank 6 starts at 0x800. When reading the fuses, we should account for this hole in address space. Similar hole exists between bank 14 and bank 15 of size 0x80 on iMX6QP, iMX6DQ, iMX6SDL and iMX6SX. Note: iMX6SL has only 0-7 banks and there is no hole. Note: iMX6UL doesn't have this one. When reading, we use register offset, so need to account for holes to get the correct address. When writing, we use bank/word index, there is no need to account for holes, always use bank/word index from fuse map.

* cros_ec: Support the LDO access method used by springSimon Glass2015-08-05-10/+11
| | | | | | | | | | | | | | | | | | | | | | | Add a driver to support the special LDO access used by spring. This is a custom method in the cros_ec protocol - it does not use an I2C pass-through. There are two implementation choices: 1. Write a special LDO driver which can talk across the EC. Duplicate all the logic from TPS65090 for retrying when the LDO fails to come up. 2. Write a special I2C bus driver which pretends to be a TPS65090 and transfers reads and writes using the LDO message. Either is distasteful. The latter method is chosen since it results in less code duplication and a fairly simple (30-line) implementation of the core logic. The crosec 'ldo' subcommand could be removed (since i2c md/mw will work instead) but is retained as a convenience. Signed-off-by: Simon Glass <sjg@chromium.org>
* dm: cros_ec: Convert the I2C tunnel code to use driver modelSimon Glass2015-08-05-5/+88
| | | | | | | | | | | | | | | | | | | The Chrome OS EC supports tunnelling through to an I2C bus on the EC. This currently uses a copy of the I2C command code and a special 'crosec' sub-command. With driver model we can define an I2C bus which tunnels through to the EC, and use the normal 'i2c' command to access it. This simplifies the code and removes some duplication. Add an I2C driver which tunnels through to the EC. Adjust the EC code to support binding child devices so that it can be set up. Adjust the existing I2C xfer function to fit driver model better. For now the old code remains to allow things to still work. It will be removed in a later patch once the new flow is fully enabled. Signed-off-by: Simon Glass <sjg@chromium.org>

* dm: Add a system reset uclassSimon Glass2015-07-21-0/+72
| | | | | | | | | | | | | | | | It is common for system reset to be available at multiple levels in modern hardware. For example, an SoC may provide a reset option, and a board may provide its own reset for reasons of security or thoroughness. It is useful to be able to model this hardware without hard-coding the behaviour in the SoC or board. Also there is a distinction sometimes between resetting just the CPU (leaving GPIO state alone) and resetting all the PMICs, just cutting power. To achieve this, add a simple system reset uclass. It allows multiple devices to provide reset functionality and provides a way to walk through them, requesting a particular reset type until is it provided.
