LDO7 (VCC10_LCD_PWREN_H) is essentially just a glorified GPIO that turns the real VCC10 regulator on or off. We tried setting it to 3.3V since it matches the VCC33_SYS voltage on the input of that regulator. However, we didn't notice that the LDO only supports going up to 2.5V. This patch changes the voltage to the allowed maximum, which should still work fine as an enable line (and is the same value used by the kernel). This removes an assertion error in the ramstage. Also change the PMIC driver to assert maximum VSEL values based on the LDO, because the lower-voltage ones support one more setting. (LDO3 is actually listed to only go up to 0b1111 in the manual, and has a weird jump from 0b1101 -> 2.2V (skipping over 0b1110) to 0b1111 -> 2.5V. I don't know if that's a documentation error or what they were smoking when they designed that, but we don't need to care for now.) BRANCH=None BUG=None TEST=Booted on Pinky, no more ASSERTION FAILED.

------------------------------------------------------------------------------- coreboot README ------------------------------------------------------------------------------- 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. Payloads -------- After the basic initialization of the hardware has been performed, any desired "payload" can be started by coreboot. See http://www.coreboot.org/Payloads for a list of supported payloads. Supported Hardware ------------------ coreboot supports a wide range of chipsets, devices, and mainboards. For details please consult: * http://www.coreboot.org/Supported_Motherboards * http://www.coreboot.org/Supported_Chipsets_and_Devices Build Requirements ------------------ * gcc / g++ * make Optional: * doxygen (for generating/viewing documentation) * iasl (for targets with ACPI support) * gdb (for better debugging facilities on some targets) * ncurses (for 'make menuconfig') * flex and bison (for regenerating parsers) Building coreboot ----------------- Please consult http://www.coreboot.org/Build_HOWTO for details. Testing coreboot Without Modifying Your Hardware ------------------------------------------------ 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 http://www.coreboot.org/QEMU for details. Website and Mailing List ------------------------ Further details on the project, a FAQ, many HOWTOs, news, development guidelines and more can be found on the coreboot website: http://www.coreboot.org You can contact us directly on the coreboot mailing list: http://www.coreboot.org/Mailinglist Copyright and License --------------------- The copyright on coreboot is owned by quite a large number of individual developers and companies.
