2015-02-06drivers/pc80/mc146818rtc: Reduce superfluous preprocessor useAlexandru Gagniuc
cmos_init() had layers of preprocessor directives, which resulted in a complete mess. Refactor it to make use of the IS_ENABLED() macro. This improves readability significantly. One of the changes is to remove in inline stub declaration of (get|set)_option. Although that provided the ability for the compiler to optimize out code when USE_OPTION_TABLE is not selected, there is no evidence that such savings are measureable.

2014-12-30rtc: Add an RTC API, and implement it for x86.Marc Jones
This CL adds an API for RTC drivers, and implements its two functions, rtc_get and rtc_set, for x86's RTC. The function which resets the clock when the CMOS as lost state now uses the RTC driver instead of accessing the those registers directly. BUG=None TEST=Built and booted on Link with the event log code modified to use the RTC interface. Verified that the event times were accurate.

2014-08-10drivers: Add I2C TPM driver to corebootStefan Reinauer
On ARM platforms the TPM is not attached through LPC but through I2C. This patch adds an I2C TPM driver that supports the following chips: * Infineon SLB9635 * Infineon SLB9645 In order to select the correct TPM implementation cleanly, CONFIG_TPM is moved to src/Kconfig and does the correct choice.

I assume from the code in the TPM driver that the TPM spec defines different types of delays and timeouts which each have a particular duration, and that the TPM can tell you how long each type is if you ask it. There was a large table, some members of a data structure, and a function or two which managed the timeouts and figured their value for different operations. The timeout values for the various "ordinals" were never set in the vendor specific data structure, however, and always defaulted to 2 minutes. Similarly the timeouts a, b, c, and d were never overridden from their defaults. This change gets rid of all the timeout management code and makes the "ordinal" timeout 2 minutes and the a, b, c, and d timeouts 2 seconds, the larger of the two default values.
