* Add configs to add flags to console commandsBill Richardson2016-08-311-0/+16
| | | | | | | | | | | | | | | | | | If we add a .flags field to the console commands data structure, we can use it to distinguish some commands from others, for example to mark some commands as safe and others as dangerous. This just adds the undefined CONFIG_ options. They aren't used anywhere, so there's no behavioral difference yet.

* pd: select dynamically Rp valueVincent Palatin2016-08-251-11/+2
| | | | | | | | | | | | | | | | | | | | | Add API to switch the Rp pull-up value on CC dynamically at runtime. This is a preparatory work for boards having a more complex maximum source current policy (eg 2 ports sharing a common pool of power). For fusb302, update the voltage thresholds for open/Rd/Ra as they depend on the Rp (was missing from the previous change).

* Remove unused CONFIG_CONSOLE_RESTRICTED_INPUT optionBill Richardson2016-08-241-7/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | Nothing has used this config option since Spring and Skate, back in early 2014. There's nothing in ToT that uses it at all. I want to add something similar for other purposes, and having two similar-sounding options will just cause confusion. NOTE: Although the comments in include/system.h said that the two functions system_get_console_force_enabled() system_set_console_force_enabled() were only useful when CONFIG_CONSOLE_RESTRICTED_INPUT is defined, they were being used in chip/stm32/system.c. But since the bkpdata registers are only accessible to the EC, there was no way to initialize or modify the one relevant bit that those functions cared about, so they almost certainly had no effect.

* Modified flash API batch write logic to respect row boundaries.Johnnie Chan2016-08-241-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | * Added MACRO for specifying row size of flash device. * Set chip/g specific values for flash row size. The flash API for g/chip will segment large write operations into a maximum of 32 word blocks for batch writes to flash memory. Prior to the change in this commit, the segmentation will adhere to avoiding crossing page boundaries (2048B) but will not respect row boundaries (256B). The flash controller will reject any write op that crosses a row boundary and set a row boundary violation code on its error register.

These two independent uses have been split into CONFIG_USB_PD_TCPC_TRACK_VBUS and CONFIG_USB_PD_VBUS_DETECT_TCPC, which sould be more clear.
