2016-03-15libpayload: Drop CONFIG_LP_CHROMEOSStefan Reinauer
This is adding complexity to the code more than it saves space, plus some of the tables could potentially be interesting outside of the ChromeOS context.

2016-02-19libpayload: honor TSC information under CONFIG_LP_TIMER_RDTSCAaron Durbin
When CONFIG_LP_TIMER_RDTSC is enabled honor the TSC information exported in the coreboot tables as the cpu_khz frequency. That allows get_cpu_speed() not to be called which currently relies on the 8254 PIT. As certain x86 platforms allow that device to be optional or turned off for power saving reasons, allow a path where get_cpu_speed() is no longer called. Additionally, this approach also allows the libpayload to not duplicate logic that already exists in coreboot. BUG=chrome-os-partner:50214 BRANCH=glados TEST=Confirmed in payload TSC frequency is honored instead of using get_cpu_speed().

2015-04-17libpayload: Take flash parameters from corebootDan Ehrenberg
A payload may want to run erase operations on SPI NOR flash without re-probing the device to get its properties. This patch passes up three properties of flash to achieve that: - The size of the flash device - The sector size, i.e., the granularity of erase - The command used for erase The patch sends the parameters through coreboot and then libpayload. The patch also includes a minor refactoring of the flash erase code. Parameters are sent up for just one flash device. If multiple SPI flash devices are probed, the second one will "win" and its parameters will be sent up to the payload. TEST=Observed parameters to be passed up to depthcharge through libpayload and be used to correctly initialize flash and do an erase. TEST=Winbond and Gigadevices spi flash drivers compile with the changes; others don't, for seemingly unrelated reasons.

2015-03-20libpayload: Consolidate coreboot table parsingVadim Bendebury
There are three instances of coreboot.c in libpayload. for x86, arm and arm64 architectures. The arm and arm64 instances are exactly the same. The differences with the x86 instance are as follows: - a very slightly different set of coreboot table tags is parsed (one tag added and two removed) - instead of checking a fixed address if it contains the coreboot table, the x86 version iterates over two address ranges. This patch refactors the module, leaving architecture specific processing in arch subdirectories and moving the common code into libc.
