qualcomm/sc7180: Clean up drivers with common clock As we move to use the common clock driver, the sc7180 clock driver, watchdog and display drivers requires few cleanups, thus update the impacted drivers. Earlier the display client is expected to provide 2n divider value, as the divider value in register is in form "2n-1". mdss_clk_cfg.div = half_divider ? (half_divider - 1) : 0; The older convention in the upcoming patches would be replaced with the common macro of QCOM_CLOCK_DIV, thus need the divider needs to be updated. mdss_clk_cfg.div = half_divider ? QCOM_CLOCK_DIV(half_divider) : 0; To accommodate impacting the functionality, the half_divider is taken care in the clock driver.

coreboot is a Free Software project aimed at replacing the proprietary BIOS (firmware) found in most computers. coreboot performs a little bit of hardware initialization and then executes additional boot logic, called a payload.
With the separation of hardware initialization and later boot logic, coreboot can scale from specialized applications that run directly firmware, run operating systems in flash, load custom bootloaders, or implement firmware standards, like PC BIOS services or UEFI. This allows for systems to only include the features necessary in the target application, reducing the amount of code and flash space required.
coreboot was formerly known as LinuxBIOS.
After the basic initialization of the hardware has been performed, any desired "payload" can be started by coreboot.
See https://www.coreboot.org/Payloads for a list of supported payloads.
coreboot supports a wide range of chipsets, devices, and mainboards.

ANY_TOOLCHAIN
Kconfig option if you're feeling lucky (no support in this case).Optional:
make menuconfig
and make nconfig
)Please consult https://www.coreboot.org/Build_HOWTO for details.
If you want to test coreboot without any risks before you really decide to use it on your hardware, you can use the QEMU system emulator to run coreboot virtually in QEMU.
Please see https://www.coreboot.org/QEMU for details.
Further details on the project, a FAQ, many HOWTOs, news, development guidelines and more can be found on the coreboot website:
